Polar V800, GPS multisport watch for running and triathlon | Full analysis


Cambiar idioma

Polar introduced the V800 earlier this year as its first GPS multisport watchThe official announcement described the Polar V800 as its smarter, more advanced clock to date.

Officially presented at CES 2014 in Las Vegas, it was not only outstanding for this, but also for being the first to incorporate an activity monitor in the watch itself, something the Finns had been working on previously with Polar LoopThe clock was released in April.

After this small entry, and before starting the analysis, I would like to clarify that the test unit is a store-bought unit. Therefore, it is not a demonstration unit with special features or any special software revision. It is simply the same watch that you can buy in your trusted store, with the same accessories and presentation.

Remember you can buy it on Amazon through this link and that way you will generate a small commission that will help the development of this page, and that you can see more tests and analysis like this one.

The good

  • Flawless GPS reception. Probably one of the best watches in that area
  • Good overall quality feel and discreet appearance for daily use
  • Route navigation
  • Barometric altimeter

The bad

  • It took a while to get a complete firmware in terms of functions
  • It's not mineral glass
  • You need a speed sensor to display the slope on the bike]B01G3R0PXU&tag=c1mes-21]B01G3R0RLA&tag=c1mes-21]B01G3R0PWQ&tag=c1mes-21



The Polar V800 is presented in a small box, quality cardboard and a careful design.

Of course, Polar also thinks of shoppers who go to the store without first checking online, so it provides plenty of information about the watch on the back of the box.

Polar V800, box

The opening is jewellery-style - when you open it, all you'll find is your new V800 Polar waiting to be put on your wrist.

Polar V800, box

Its contents will depend on which version you buy, as you have the option of buying just the watch, or buying it as a "kit" along with the Polar H7 pulse sensor. The test unit is black, but Polar also sells the watch with the strap in deep blue. So if you find the black watch too sober, you may want to consider getting the blue version.

All this is what is included in the small box. Certainly, the Polar V800 travels pretty close to your home (tourist category they call it).

Polar V800, contents

The data is loaded and transmitted via a cable with a clamp.

It is very easy to fit, as it fits perfectly with the strap and there is no possibility of making a mistake.

Polar V800, connected

This is the pulse sensor that incorporates, the Polar H7, along with the chest strap "soft strap". This sensor stands out for its connection via Bluetooth Smart and analog transmission. Bluetooth Smart (or Low Energy) is a low energy technology compatible not only with the watch, but also with phones that support this type of connection (among others). The analog transmission is useful when doing aquatic activities, since the Bluetooth signal is not capable of transmitting underwater, so it will use the 5kHz band to carry the pulse information to the watch. In addition, it will also be compatible with gym machines that support this transmission band.

Polar H7

The anchoring system is the typical one, through two clips to the tape itself, which is also standard measurement. Although the compatibility between sensors and tapes is not 100% safe. For example, the Polar sensor on a Garmin tape connects perfectly, but not the other way around, since the Garmin sensor's attachment is not totally safe on the Polar tape, and at the slightest touch it separates from the sensor.

Polar H7

But let's go to the watch itself. Stainless steel case, 128×128 pixels screen resolution and Gorilla Glass coating. It has a total of 5 buttons, made of aluminum. Three on its right side where the red button stands out panic-stricken The two buttons that flank it are the ones used for navigation.

Polar V800, picture

On its left side we have the two missing buttons, the one to exit a menu (back) and the one for lighting, but all these buttons are doubled in their usefulness, because if we leave them pressed, we will access other different options, such as changing the presentation of the watch, accessing the favorites menu or starting the Bluetooth synchronization.

And if we turn it over, we see the connection for charging and data transfer.

Running with the Polar V800

Probably when using the Polar V800 to do a workout, it'll be running where it's most comfortable. Not because it's bad like bicycle watch (which is not) or from swimming As with all watches, it is not going to be easy to access all the information on the handlebars of a bike, so if your main training is based on two wheels, you might want to think more about bike-specific equipment.

The first thing we should do is to configure everything to our liking. If we press the red button, we see the list of sports that comes predefined from the factory, but that we can easily configure from the Polar Flow to include the profiles of the sports that we will practice more often, like for example Beach Volleyball or Nordic Walking, something that I suppose you do every day. In addition, the information on screen is also customizable, but not from the clock.

Just go into Polar Flow and by clicking on our name we can select the sport profiles.

Sports Profiles, Polar V800

If we enter to edit any of them (in the case of Running), or we create a new one, we can configure the training views. We can also configure the GPS recording speed (or disable it), the lap configuration or the heart rate zones, all configurable according to each sport.

But we were with the training views. We can configure up to 8 different views with a maximum of 4 variables per screen. That is, a total of 32 data while running. Of course it is possible to select less amount of information, and thus make the space occupied on screen by any variable greater.Training Views, Polar V800

The data we can include in the views are the following,

[table id=14 /]

*Cadence data will only be available if you connect the Polar Bluetooth Pedometer, at least until the update that enables the internal clock accelerometer to collect this data.

Polar V800 Views

Once we have the clock ready to show the information we are interested in, we tied our laces Press the red button and select from the list of sports profiles the option to run.

After selecting the running activity (or if you have changed it to mountain trail, track or field, whatever), it will start looking for signs. On one hand sign GPS and on the other hand the Heart rate monitor and the pedometerThe satellite search, despite not checking position every time we synchronize the watch, is quite fast. Of course it is not as fast as other watches that do receive the position of the satellites previously, but still the differences are not noticeable. In this video you can check how fast it finds enough satellites to start our training. It is a cold search, one day after the last training and in a different place. I have not made it easy, but it is not always that fast.

It is always a good idea to use this satellite search time to stretch a bit and not start so cold, but try not to move too much while doing the satellite search because it will take more work to fix the position.

And if you forget to start recording the activity during this time, don't worry, because the Polar V800 is so smart that it reminds you that you are not recording anything. Who hasn't noticed that they have started training and after 20 minutes have not recorded the activity?

Recording warning not started on Polar V800

An important detail that has arrived with the last update: now, when you connect a pedometer, the watch will take the rhythm and cadence of the pedometer and the distance from the GPS data. Previously the distance was also determined by the pedometer itself, but unfortunately the Polar V800 will not take data from the internal accelerometer to give the cadence.

However, the use of the pedometer will be more useful indoors, as the update of the rhythm through the GPS is quite fast. This has a positive and a negative reading. The positive part is that when a change of rhythm occurs, the watch will quickly update to the current rhythm, without having to wait to see if the rhythm we have accelerated to is the one we are looking for for our training. The negative part is that it is more frequent to see unrealistic variations in the instantaneous rhythm due to a momentary bad reception of the signal if you are running between trees and buildings. If you lose the signal for a second or two it is possible that you are running at a steady pace of 4:45 min/km and suddenly on the watch you see a jump at 6:00 min/km. But don't worry, this is normal behaviour.

In this video you can see how the indication of the rhythm varies by taking the data through the GPSIt starts at walking pace, accelerating to race pace to stop at walking speed, and then back to race pace.

Training with objectives

Running is not just about wearing your shoes. Many of us are looking for more personalised training than just going kilometre by kilometre, so the watch we choose has to be capable of being our own trainer. Unfortunately in the case of the Polar V800 the options are not yet very extensive (although Polar has promised updates in this field).

We can create a quick workout, where we simply set the final goal defined by a total time, a distance or a number of calories. The first can be used to set your last time at 12 km, for example, and go for a run with that time limit to try to improve it. The second case would be the typical distance workout. And the third case, can be used perfectly to make room for that pizza you're going to put between your chest and back and not have a guilty conscience.

Polar V800 Speed Training

This type of training can also be selected directly from the clock. And once you are training, it presents us with a graph with a percentage of what we have completed, depending on the training objective: duration, distance or calories. In the case of the image below, the objective of the training is simply to cover 2 kilometres. After covering 90 metres, it indicates that we have already covered 4% of our total training.

Polar V800 quick lens

Then we can choose the race pace, similar to the previous one but choosing two variables. Let's say we want to train 10km at a 4:30 pace. Then we enter the data and automatically calculate the duration of the training.

Polar V800 Running Pace TrainingOr do 2km at a rate of 5:00min/km.

Polar V800 Favourite Menu

Basically, it becomes a "Virtual Partner"and to our previously chosen selection of displays, another one will be added to indicate how you are doing with reference to the target (currently 3 seconds behind), along with information on your current pace, distance to finish target, average pace and heart rate.

Polar V800 Virtual Partner

The last available choice is to do a training with phases, or as we usually know it, intervals. This is where the main lack is shown, since the only objective we can set for each phase is a heart zone (or do free training). It does not give a choice to perform training with a variable paceThe speed or cadence, which is quite common.

  • With the 1.3 update for the Polar V800 (December 30th 2014) it is now possible to select a pace as your training target.
  • Also, the 1.4 update adds "Zone Blocking" trainings. Click here for all the details of the new update

In addition, when creating a workout, we cannot keep them as standard workouts, but create them as a diary. We create them with a certain date and then access the agenda and can select that workout.

If we want to do a recurring workout, we can add it to favorites and launch it from there. But it's a bit more chaotic than the usual "search workout", "select" and run. I guess it's a matter of habit and seeing it with Finnish eyes.

However, we can select the duration or distance of each part of the training, one or more target zones, the name of each part, etc.

Polar V800 Phase Adjustment

We include it in the menu of favorites, and from there we can launch the training whenever we want.

Polar V800 Favourite Menu

This is the screen that will be added if you do interval training.

Interval training with the Polar V800Anyway, the way to create the workout is somewhat chaotic. We can't create a repetition of intervals and breaks until we have programmed the whole workout, or we can't add anything else. That is, if we prepare the warm-up part, the intervals and do the repetition, then we can't program a cool-down since everything will be blocked until we remove the repetitions.


Polar has had a tremendous detail with which we are used to training at night. And not only because the lighting in the dark is very good

But because it is possible to leave it always on through the quick menu, so you don't have to look for the button every time you want to see a record. Always on and at a glance we know our pace and distance.

Information after training

At the end of the training session, 1TP10We can pause it by pressing the "back" button once, and we will return to the activity start screen, but with the time we have already spent training.

You can resume the activity by pressing "start" again when you are ready, or press and hold "back" for three seconds to delete the workout. If the session was short, the Polar V800 will ask you if you want to save it.

These laps can be set automatically so that the watch can set them, and you can also create laps manually (and in parallel to the automatic laps) by simply pressing the red button while training, and if you don't feel like looking for the button you have the option to simply tap the screen. It's not that it has a touch screen, but it is capable of detecting these taps on the screen through the integrated accelerometer.


Talking about cycling in a multisport watch does not present many demands. Basically we are facing the same requirements as when running, and the only thing it should be able to offer us is support for various sensors. The watch should go from supporting a footpod or accelerometer, as it does in the running mode, to allow connection to cadence/speed sensors and, something quite in demand now, power meters.

It is precisely this support for power meters that has recently been incorporated through an upgrade in the Polar V800. At the end of August Polar announced the Kéo Power Essential at a price of 999 euros. These types of sensors are designed to obtain information about the power in watts that the cyclist is able to apply to the pedals.

After the update 1.4The Polar V800 can also be connected to potentiometers of other brands.

Otherwise, the operation is exactly the same as the race mode, but we can replace the pace metric with speed in km/h, which is more appropriate to the sport in question. I will not repeat all the training functions because they are the same as in the race mode.

Polar V800 on handlebarIn addition, we can also create an indoor cycling mode. This way we can deactivate the use of GPS to replace it with the cadence and speed sensor and obtain data from them (just like we do outdoors). It does not represent a big change from the outdoor mode, but being able to deactivate GPS gives us that extra autonomy that may be interesting to take advantage of at some point. And besides, spending battery for spending, does not have much logic.


When Polar presented the V800 at the Las Vegas CES in 2014, it promised an ideal watch for triathletes, not only because it has a specific triathlon mode, but also because it has the ability to assist in water training, both indoors and outdoors.

Well, at the beginning of November 2014 we still don't have the capacity to train with the Polar V800 soaking in the water. So what works when it comes to getting in the water to swim? Not much really, exercise time and heart rate (only with the Polar H7 sensor). Polar has promised to bring pool metrics such as as , SWOLF or distance (both indoors and outdoors) by the last quarter of 2014. We are in that quarter and there is still no sign of these metrics, although they have updated dates again and promise to have the update ready by mid-November.

Swimming with the Polar V800

Even so, the V800 is one of the few watches that can use heart rate information for training purposes. This has been a typical feature of Polar watches, as it uses the 5 kHz analog band for its pulse sensors. The H7 sensor that comes with the V800 (if purchased as a pack) supports Bluetooth Smart communication, which is what we will mainly use in all sports, but also analog connectivity. Unlike Bluetooth Smart, it does work underwater, so if you are using the V800 with another sensor than the H7 (Polar H6 or a sensor from another brand) you will not have heart rate information when you are swimming. In fact, I have not had a chance to test it with the wristband Mio LinkIn swimming mode, it will not search for the Bluetooth sensor, but only for the analog one.

Underwater Clock

In swimming mode it is not possible to have the GPS activated. There is still no specific mode of open water swimming, which will arrive in March 2015.

The problem of not having a specific outdoor swimming mode is that the GPS signal is lost every time the watch is submerged in water. Therefore, more than a technical problem (the operation of GPS is as it is and has no further solution), it is a "mathematical" problem. When a manufacturer includes an outdoor swimming mode, simply what it does is to apply a correction algorithm that will help adjust the track, starting from the points that podido has been saving and making the calculation of where we are going to minimize errors. This is something that other manufacturers such as Suunto or Garmin are already doing, but that Polar is still developing.

Polar 1.2 Update

Following the update to version 1.2, pool metrics are now available. For this, in addition to launching the update itself for the watch, Polar has also added a new sport profile in the Polar Flow web application. Now you have to select "Swimming in pool", thanks to which the watch will activate the internal accelerometer to show you all the relevant metrics when swimming.


The first thing we have to do is to set the length of the pool. The clock allows us to select a 25m or 50m pool, and if it doesn't fit our particular training location, we can make the selection manually. That is, if any pool doesn't fit, the minimum distance will be 20m.


And the next step is to dive into the water. The Polar V800 is able to recognize not only your swimming style (backstroke, butterfly, freestyle...), but can also identify when you have reached the end of the pool and are starting another swim.

It will also give you your SWOLF number. For those who don't know what it is, it's a way of numerically representing how you swim. The name comes from mixing swimming and golf (SWimming and gOLF). SWOLF takes into account how long it takes you to complete a length and how many strokes you need to do it, all based on the size of the pool. And just like in golf, the lower the number of "strokes" you need to complete a length, the better.

This is a relative value, so the comparison between different people does not make much sense, but rather it is a valid figure to compare yourself between different sessions.

In short, this is all the information that the watch gives you: your swimming style, how long you have been swimming and the total distance you have swum.

Swimming Metrics 1

In this case, the clock has identified the session as a back. If different styles are used in the same session, the clock will then identify all of them and separate them.

Swimming Metrics 2

Average and maximum rhythms...

And of course, all this information is then sent to Flow, so that we can do a full analysis of our swimming session and see how we are improving.

Polar 1.5 Update

The open water mode is now available, but it has been delayed a little longer (oh, surprise), and the update has been made available in July 2015.

Modes for triathlon and multisport

The Polar V800, let us remember, is a watch that is also designed for triathlon, and to be considered a valid watch for this sport, it must have a specific mode of operation in which to combine swimming, cycling and running.

Polar V800, triathlon mode 1

When we enter the Triathlon, we again have the possibility of selecting a sport. Logically, the first sport to appear will be swimming.

Polar V800, triathlon mode 2

Once the exercise is over, the watch will give us a report on the duration of the session and will return to the sport selection. The next one, cycling, will automatically appear. The time that appears would be the one corresponding to the total we have been running.

Polar V800, triathlon mode 3

After selecting the next sport (in this case cycling) another screen will appear, indicating the transition time, that is, the time that has passed since we have told the clock that we have left the water until we are leaving with the bike.

Polar V800, triathlon mode 4

Once we have finished the cycling exercise, we press the pause again, receiving a summary of exercise information.

Polar V800, triathlon mode 6

And it returns, again, to the sport selection page, to automatically display the running activity.

Polar V800, triathlon mode 7

And when you select to start the activity, it indicates again the transition time from cycling to running.

Polar V800, triathlon mode 8

That again we will finish and when pausing the exercise, we will have the final summary of the exercise, and the triathlon event will be over.

Polar V800, triathlon mode 9

Once the race is synchronized with Polar FlowBut it will not be three different activities, but we will have a single activity in which all three will be combined, together with the transition times and the details of each of them.

Here we have total time together with time in each activity, distances, transition times and of course the map.

Triathlon Competition with Polar V800

Clicking on each activity we will have the detailed information of each one of the activities.

Finally, the Polar V800 has an extra, multi-sport free mode. It's similar to the triathlon mode, the only difference being that you can choose from all the sports profiles we have programmed. That is, if instead of doing a triathlon you have a duathlon, you can use this mode to track in exactly the same way. Or you can run to the gym and do some weight training, selecting the running sport first and then selecting strength training. The possibilities are almost unlimited.

Polar V800, multisport mode

The activity will be displayed in Polar Flow Just like a triathlon, one activity will be divided into several different activities when you enter.

Battery life

Another aspect that the Polar V800 excels at is its battery, despite its relatively small size. Thirteen hours of autonomy using the GPS recording data every second. It also has different modes of use with which to further increase the autonomy.

V800 sheets

To begin with, if we use the watch as an instrument to give us the time (and record our activity, since it is not possible to deactivate this function), Polar announces a total duration of one month before needing a charge. But I guess this for most people who read this test will not be a very important value to take into account. Here the important thing is its autonomy when the GPS is connected (remember, thirteen hours). If this is not enough for you or you plan to do an ultra trail, you can change the data recording mode to 60 seconds for GPS (but still receive data from other sensors). This way you can get up to more than 50 hours in sport mode.

Energy Saving Function in Polar V800In all the time I've been testing the watch, I've never had a battery problem. Whenever I've wanted to do an activity, I've been able to finish it without any problems, something that other watches have been able to suffer from when they've run out of battery in the middle of training. I haven't been able to carry out an exact test to see if the figure announced by the manufacturer is real, but it certainly does match the official data.

Sailing with the Polar V800

V800 wood

The Polar V800 is presented as a great option for navigation routes, except for one small, great detail: for the moment, in Polar Flow we don't have the possibility to create our own path. We can only create a favorite of an activity performed. Luckily, I found the temporary solution to be able to add any GPX path downloaded from, for example, Wikiloc. You can find the method here: Import GPX routes to Polar V800.


Polar has updated Polar Flow and now it is possible to import a route in GPX or TCX format that you can mark as a favorite, so you don't need to follow the procedure described above.

Polar V800 Navigation

When we start sailing, the first thing we have to do is to calibrate the compass. To do this the watch asks us to shake our wrist (or the watch if we don't have it on our wrist, which I'm watching you with the watch stored and moving the wrist...) making eight-shaped turns.

Calibrate compass on Polar V800

And once calibrated, the compass will show us the way to go.

Polar Compass V800

In other watches without a compass you might find a similar feature, but we will have to move around so that the watch can interpret our position and know where we are going. In the case of the Polar V800 it is not necessary, as it shows us exactly our way even if we turn round, as seen in the video.

And once the compass has taken you on the road, the Polar V800 will show you the route through a map, which displays your route and the distance to finish it. It also shows a small arrow with the direction in which you should continue the route.

Polar V800 Mapping Navigation

But... what happens when we get lost and move away from the route? To start with, the distance to the target will increase instead of decrease. And the target symbol you saw before will change to an empty circle. You can see in the video how it behaves.

The procedure once you get close to the route is the opposite, going from an empty circle to a circle with a target when you find the path that will take you to your destination again.

In addition to the navigation function itself (which you access from the favorites menu) in any race mode you can find different options that will help you in case you get lost. By pressing and holding the "light" button you can access these options. You can know your exact location (in case you need a rescue).

Polar V800, points of interest

You can add some points of interest, to which you can return.

Polar V800, points of interest

And in every training mode you have a screen that shows you the way back to your starting point, but it won't show you any path, just a compass so you know where you started from, so if you're in the middle of a mountain, it will show you the squirrel trail, from branch to branch.

Back to the top with the Polar V800

Polar V800 as an everyday watch

One of the most important things Polar has done in the V800 has been to make it your everyday watch. Watches for sports and specifically triathlon have always been rather bulky devices that in some cases did not even have a basic watch mode (such as the Garmin Forerunner 305, 310XT or 910XT).

The V800 has a very careful design, both in terms of aesthetics and the materials used. The body is made of aluminum and stainless steel, with aluminum buttons. The main button is decorated in red "Polar", and the case slightly overlaps the screen, with Gorilla Glass protection, to try to save it as much as possible from any kind of blow or scratch. On the side with only two buttons is a nice V800 engraving, while on the strap buckle, also made of aluminum, it is "Polar" that is engraved. The strap is made of high quality rubber, with light knurling.

Through the menu, or by pressing the key marked "Up", we can choose the "dial" of the watch. These are the possibilities available to us

  • Date and time (without seconds)

  • Date and time with seconds along with your name

Polar V800 Watch

  • Analog dial with date at 3

  • Time only, in large numbers and two lines (option I have chosen)Polar V800 Watch

Of course, we can also set an alarm and choose between one-time, Monday to Friday or daily scheduling. This alarm menu can be accessed from the general settings, or by pressing the "Light" button, which is the quick menu for other functions.

Polar V800 Watch

What's surprising is that the clock doesn't adjust the date automatically with the values received from the GPS. The date and time adjustment is manual, just like when the time changes from winter to summer and vice versa. It's surprising that for a clock so advanced in many aspects, that something so simple has not been implemented. But well, it's not every day that you are changing the time (unless you travel a lot to areas with different time zones).

Activity monitor

The Polar V800 was the first to incorporate the activity monitor function. This function was later added to its little brother, the M400. It was a logical move, especially after the wearable fever that hit the market in 2013 and 2014. In this day and age, if you want to be somebody in this "fitness gadget" thing, you must have one. Garmin, Polar, Nike, Jawbone, FitBit, Samsung, Runtastic... Practically every company in the industry has released its version. And that's in the well-known companies, because in Chinese products sold to other brands as OEM it's hard to keep track.

As I was saying, the Polar V800 was the first GPS watch to include the activity monitor function. And much of its aesthetics is due to this small detail. Until the introduction of the V800, we were used to sports watches that we normally wore to train and took off as soon as we entered the shower... and until the next training session. But the Polar V800 is designed to be your everyday watch, with a much more traditional look and could perfectly pass for a simple 30 euro digital watch (nothing could be further from the truth).

In this way, Polar offers us to analyze our daily life. On the one hand with the GPS watch to record our sports performance and, when we stop practicing sport, quantifying our daily life. The V800 will tell us how we have trained and will also take into account those walks through the streets of Carrefour looking for the scouring pads or what you have walked after parking the car "under" home (three neighborhoods beyond yours). In short, your activities during your time as an athlete and the rest of your daily activities when you stop being an athlete.

What we should know is that, unlike most activity monitors, the Polar V800 does not show any information on screen. No steps, no distance covered, just a bar that is completed as we go along. To see the details we must synchronize it, either with the computer or with the mobile (if you have an iPhone, if you use another platform, at the moment only with the computer). And then we can know all the details of the activity.

Activity in Polar V800

It estimates steps taken, distance and calories consumed. And if you leave your watch on at night while you sleep, it will also analyze the quality of your sleep (yes, I have to sleep more). In case you stay more than 1 hour without moving (for example, sitting at a table in the office), it will write down an inactivity alert. But strangely enough, you don't receive any kind of notification on the watch to warn you, it only tells you when it is time to synchronize, thus losing all the purpose that this function has. Polar says that it will come in a future update, but I think that is an important aspect that should be present from the beginning, and that is not very complicated to implement.

This activity is also shown in a 24h graph. At the bottom the total hours in each activity, and in the "donut" it divides the activity according to the hours of the day. In my opinion, reviewing yesterday's activity, it fits quite well with the schedules and agrees with what I did during the day. This is what you can see directly on the website of Polar Flow.

Polar V800, activity summary

In the iPhone application, it displays information in a very similar way.

Polar 1.2 Update

Since the new update, things have changed a bit. The first thing they include is a bit of logic. Before, the activity bar was completed as the day went by (RMB), in addition to having another activity bar, which was the really important one.

Now everything is centered in the same place, and the basal metabolic rate is not included, but it does take into account our activity. If we do nothing or leave the clock stopped, the bar will be empty.

This has also brought a new view for the clock, with the bar always visible. It is animated, and when you walk or do an activity (other than training, of course) you will see how it fills up point by point.

New Activity Monitor 1

Now the activity menu is displayed much larger, with the bar and a percentage.

New Activity Monitor 2

And by scrolling down the menu you can find out how long you have to do a certain activity to complete the day's goal, whether it is walking...

New Activity Monitor 5

Standing up...

New Activity Monitor 4

Or running.

New Activity Monitor 3

These goals are set through Polar Flow, because with the new update it is possible to select the level, depending on whether your daily work includes a lot of physical effort or if, like me, you are a desktop "entity".

Activity objective


Not only that, but the lack of activity warning has been added to the clock itself, that one that only appeared on the phone and after synchronizing, and that way it didn't make much sense to use. Now the clock warns us if an hour passes when we haven't moved, to activate us and move around a bit.

Inactivity warning

Smart Coaching

The Polar V800 has a software-level functionality designed to help you. The watch can guide you through your training, and will tell you at the end of the training session the benefit of your training. With the recovery status function you can program your next intense session, taking data from your daily activity as well as your training load. In short, a circle around which everything revolves and which will keep you in control (and motivated). But I'd better explain what each option is.

Training load

When you finish your training, the watch indicates the degree of effort you have put in, and transforms it into recovery time. To make the calculation, the Polar V800 will take into account different factors, such as gender, weight, height, FCmax or VO2max, among others. Starting from the initial data, and analyzing the heart rate during training, it will evaluate the training load, and from there, the estimated time of rest. We can find the following:

  • Extreme: over 49 hours of recovery
  • Very demanding: 25 - 48 hours of recovery
  • Demanding: 13 - 24 hour recovery
  • Reasonable: 7 - 12 hours of recovery
  • Smooth: 0 - 6 hours recovery

Training load, Polar V800

Recovery status

The V800 determines your recovery status from the daily activity measured by the activity monitor along with the load from past training. Once the data is analyzed, it will calculate your recovery status and how long you need to be ready to train again.

It is represented by a bar that will move between high stress, tired, balanced and untrained states and shows when you will reach the next level of your recovery (with day and time).

During the training I have done I have found that the recovery state values have always been quite faithful to how I was feeling. It is easy to know that after a strong 15km workout you will be tired, but not so tired that you can tell yourself, for example, that on Tuesday at 12:00 you will be at a balanced point. And when the clock indicated that state, I certainly felt that way.

Recovery Status, Polar V800

Training benefit

The training benefit is another piece of information that the watch gives us when we finish training, giving us indications of how the training has been and the benefits that you will obtain from it. It is based on the heart rate zones, the time of training and the calories burned.

Training Benefit

These are the messages we may receive, depending on the training we have done.

Training Benefit

Running Index

Finally, the Running Index gives you a way to monitor changes in your running performance. It will take into account climbs and descents, and to provide a real value you need to have set your resting and maximum heart rates correctly. In the watch's manual you can also find a table with an estimate of times that you can run in different events, from 5 kilometres to a marathon. In my case, these times are slightly optimistic (or it's just that I always run against the wind, who knows), but they are not very different from what I can achieve on a good day that I feel inspired. So it is a good guide when planning a first race in a new distance.

Running Index Polar V800

Physical evidence

The Polar V800, apart from the activity monitor and the Smart Coaching, has a series of physical tests (some need accessories not included). In total there are four tests from which we can obtain information: orthostatic test, fitness test, jumping test and RR record.

Polar V800 Physical Testing

Orthostatic test

It is aimed at controlling the balance between training and recovery, and is based on the measurement of heart rate and how it varies, as it reflects changes in the autonomous regulation of the cardiovascular system.

The first time the test is performed, six measurements must be made in two weeks to obtain a reference value.

It's easy to do. With the pulse sensor on and sitting down and relaxing, the Polar V800 will ask you to lie down for 3 minutes and then stand up for 3 minutes. The results it will give us are the resting heart rate, standing heart rate and FCmax, which we can then compare with previous results to see how our evolution is.

Orthostatic test

Fitness test

Polar helps you calculate your resting aerobic fitness, which Polar calls Polar OwnIndex. It ensures that this value is comparable to your maximum oxygen consumption during exercise (VO2max). You can do initial tests to get a baseline measurement, and then month by month as you train, you do the test again to check your progress.

This test is the hardest physical test you'll ever take with the Polar V800. In short, it's all about... lying down. That's right, you simply put on the pulse sensor, lie down and relax. Start the test and wait. Easy, right?


Jump test

In this case we would need an accessory not included, the Polar Bluetooth running sensor (the pedometer).

We have three types of tests that will give information about your explosive strength and anaerobic power. There are three tests to choose from: squat jump, countermove jump and continuous jump. The clock will only show the result of the last test in this menu, but you can access the previous results through the calendar and, of course, through the web service.

Polar V800 Physical Testing

RR Registration

The RR record measures the heart rate variability between each beat. To perform the test, simply put on the heart rate sensor and perform the test. The results will indicate the duration of the test, the start time and the end time, along with the minimum, average and maximum heart rate.

RR Registration

Polar Flow

For the time being Polar Flow is a beta application. And as such it is indicated at the top of the page. In some aspects you can tell, because the information it provides is not the most complete. Other manufacturers have more developed products, with more customization and more possibilities. But although other services are more complete, it must be said in your favor that it meets the basics we can demand (and even a little more).

As soon as you enter the web application the first thing you see is the Explore section. We have a map full of routes made by users with their Polar M400 or Polar V800. It can be useful if you search in your area, not only to find the routes of friends, but also to find routes to save as favorites to make, or to try to improve the time to make it.

Explore Polar FLow

Our timeline is located in the Channel section. Here we find all our activities chronologically, as well as those of our friends. We can write comments or click on Analyze to enter the activity.

Polar Flow Channel

This is the activity information you will find when you click on Analyze. A global summary at the top, the map of where we have run and the typical graphs of pace, heart rate and altitude. From here it is also possible to download both the route (as a GPX file) and the training (as a TCX file), which podrás can then upload to any other platform that supports this type of file. To do so, just click on "Export Session".

Polar Flow Activity

In the previous image you can see the manual lapses (those that we do by tapping the screen of the Polar V800). But if we click on automatic lapses we can see the lapses as we have defined them previously. And if we have not done it, in the option of dividing in lapses you can do it in 0,5km, 1km, 2km or 5km.

Laps Polar Flow

If you click on "More" at the top of the workout, you will not only expand the activity information, but also have access to edit some details, such as duration, distance and sport. Or add a "feeling".

Polar Flow Edition

And a rather curious option unique to Polar (or at least, I haven't seen it anywhere else). It is the "Back to live" function. Polar will generate a video with details of the route, some photos taken from Street View and all enlivened with music. Perfect for reliving those special training days, or the races in which you have obtained the best result.

Relive Polar Flow

Our activities will also be found in Agenda, of course. Here we will have them placed on a monthly calendar with a small summary of each activity, along with the total exercise at the end of the week in time, distance and calories. That little symbol that appears on some of the days are inactivity warnings generated by the monitor. But certainly, represented like this and after time has passed, they do not make much sense.

Polar Agenda FLow

If we access the recovery status from the agenda, we will have in a graphic way and in the time frame we tell you, how tired we are, and what our evolution has been. Perfect for planning stronger trainings or recovery stages.

Polar Flow recovery status

And speaking of more graphs, we can also access our total progression, which we will be able to unravel and see what the development of our training has been. In the lower part we can summarize our best figures, in which areas we have worked, what sports we have practiced and how our activities have been developed (Training Benefit). We can spend quite a bit of time analyzing data from here, always with the idea of planning future training better.

Polar Flow Progression

From the top menu we can access, by clicking on the name, the profile, general settings, sports profiles and if we have several Polar products compatible with Flow (Polar Loop, Polar V800 or Polar M400 at the moment), we can access them.

Polar Flow Profile

This is the favorites tab, where we have stored our favorite routes, or recurring workouts. Remember that if you want to add a new route to explore that you haven't done yet, Polar doesn't allow you to upload a GPX file and then synchronize it to the clock. Let's hope that it doesn't take long to incorporate it into the application, because without this detail the navigation function loses a lot of sense.

But as everything in life can be fixed, here is a tutorial for poderlo to do it in an "unofficial" way: Importing routes to Polar V800 from Wikiloc

Polar V800 and its connectivity

The Polar V800 is one of those new products that seek connectivity between multiple devices. Everything is based on the Bluetooth Smart standard (Bluetooth 4.1 in the case of the V800), a low power consumption profile, thanks to which it is possible to connect to the different devices that the Polar V800 supports. Pulse sensor, foot or bike cadence sensor, speed sensor and even pedaling power from the beginning of October. In addition, it is also possible to connect it to mobile phones that use the same Bluetooth Smart standard, although at the moment there is only an application compatible with iPhone phones. Polar announces the availability of the application in Android by the end of 2014.

Thanks to the 1.3 update for the Polar V800 and with the application available at the Google Play Store from December 31st, the Polar M400 is now compatible with Android. They promised it by the end of 2014 and they have fulfilled, by a hair's breadth...

Anyway, with the release of the Polar M400, it is quite likely that right now the Android application is among the priorities, since it seems that the basic swimming functions will be covered by mid-November.

Synchronizing Polar V800

One of the significant features is the possibility of the Polar V800 to re-emit the pulse data to connect to other devices via Bluetooth. This way we could connect the Polar V800 with our heart rate monitor and at the same time have pulse information in the gym machine, in our phone or in a computer on the bike. But this is true in theory, although in reality it does not work as it should. At the moment, the heart rate can only be sent to Polar Beat, nothing else. This is because the Bluetooth 4.1 standard is really new, but no manufacturer supports this part of the standard

Polar V800, pulse emission

This operating feature is due to the operation of the Bluetooth devices themselves. In the case of ANT+ connectivity, the relationship between devices is equal to equal. But in Bluetooth Smart it does not work like this, as the relationship between sensors is master/slave. Therefore, each slave (in this case the frequency sensor) can only have one master (the Polar V800). For this reason in devices that support ANT+ it is possible to have heart rate for example in the watch and in the bike computer coming from one sensor, but at the moment Bluetooth does not work like this.

And after a couple of updates, the Polar V800 also becomes a smartwatch, allowing you to see on the watch screen the new messages you receive on your phone. Polar has included this possibility after software update, for receiving notifications on both iOS and Android phones.


Since the release of the Polar V800, one of the commitments of the Finns has been to update their product, which has mainly served to eliminate the failures they have identified. So far it has received a total of 6, but the schedule of updates is still pending the most important.

And this is where it has received the most complaints from users; not only because of the lack of some features that were announced from the beginning (mainly pool metrics), but also because Polar has been providing dates when they would launch the update, but which they have not met.

The pool metrics were promised for the end of October, but again it has been postponed to two weeks later, in mid-November, and will be accompanied by an update for the activity monitor, probably covering step and distance information, just like the Polar M400 has.

These are some of the most important updates we are waiting for the Polar V800:

  • Open water swimming: end of 2014
  • Creating Navigation Routes from Polar Flow: late 2014
  • Adding activities manually in Polar Flow: late 2014
  • Mobile phone notifications on the clock screen: Q1 2015 for iOS, Q2 for Android
  • Swimming pool metrics: second week of November
  • Activity monitor, extend information on the clock with steps and distance: second week of November
  • Expanding the possibilities of training targets in Polar Flow: end of 2014
  • Android application: end of 2014
  • Inactivity warnings on the clock: no date scheduled

This is only an approximation, both in specifications and in estimated dates. It is possible that in some updates something is added that is not previously programmed, and that the dates vary. Knowing Polar, these updates will arrive for sure, because once committed they will carry out the development. But as we know them, the deadlines initially set will surely be extended.

As Polar continues to update the V800 I will try to keep this section up to date.

July 2015 update: After releasing version 1.5 for the V800 and updating Polar Flow, taking out the beta version application and allowing to add activities manually, the clock is almost finished, unless you can create navigation routes (which won't take long, as it is something they have to do also for the Polar V650).
Update May 2016 - After updating Polar Flow to allow route import, Polar has finally managed to catch up with everything that was pending in the V800. This does not mean that you will not receive more news, on the contrary. For example Polar has already announced that there will be support for GoPro.


Polar has managed to create a very good product on the hardware side, but so far not so good on the software side. The feeling I have after testing the Polar V800 for several weeks is that it is on its way to becoming a rounded product. The watch is very comfortable and of an indisputable manufacturing quality. Coupled with a different aesthetic than usual in sports watches makes wearing it all day (taking advantage of the activity monitor) is not something very strange, and certainly will not clash in "less sporty" social environments.

The Finns still have work ahead of them, especially with the pool and open water training options; something that had been promised from the start and that after 6-7 months on the market they still haven't incorporated. Likewise, the lack of an Android application affects many users, and the fact that the Polar web application is still in beta mode doesn't help them either.

But there's always a positive reading: Everything is solutionable, and I'm sure that at Polar they are working on the 110% to improve it. The basis, which is more difficult to achieve, they have. A watch loaded with sensors and options that you expect to find in any watch in 2014. I'm sure that when Polar polishes the defects of the V800 in the coming months we will be facing a tough competitor in the market, which Garmin and Suunto look at with respect. With an official price of 399 ? for the version without a pulse sensor and 450 ? for the complete pack, it is already possible to find good offers that reduce this initial price quite a bit.

I've been surrounded by electronic devices of all kinds for more than 25 years. Using them, testing them, taking them apart and dissecting them. Long distance triathlete: I swim, run and cycle for a long time. Maybe too much.

  1. Hello very complete review, looking forward to receiving the heart rate monitor and I bought it before reading you, it is the first that I will have in property, I was considering buying one of deca and look what I've caught, I have always trained by feelings and crazy....jajajajaja as I run I do bike and swim it is assumed that I will give quite a lot of use. A question is it compatible with the mio link bracelet? And your reading is reliable, pq pillé a tomton cardio in mediamark and I returned it the next day pq not well counted the pulses and the gps had a significant deviation to download the routes, maybe I played the defective. Again great job.

    1. Yes, in fact I've been using it mostly with Mio Link. It works with everything except swimming, as it doesn't do Bluetooth search, but 5kHz.

      1. Hi, I've had it for 2 weeks and very well, waiting for updates, I wanted to ask you if you know of any silicone type protector for shocks, since I use it for extreme sports, thanks

  2. Excellent rewie... Really

    One doubt, or several... the quality of the m400 and the v800 in terms of finishes, materials and the design of the watch itself is the same? And the way the information is presented? In short, are the m400 the same limited watch because it is only suitable for running? Or is the v800 a completely superior watch?

    And you confirm in your test that with this watch you can follow tracks??

    Thank you once again for this excellent report

    1. As far as materials are concerned, they have nothing to do with it, since the V800 uses aluminium while the M400 is plastic. The screen is the same.

      We can talk about the M400 as a trimmed down version of the V800, yes. The M400 has all the sports modes, but no smart coaching and no support for external sensors other than pulse.

      And yes, I've made routes downloaded from Wikilocs without any problem. You have to do the described method, but you can.

  3. Congratulations. I have been a Polar user for several years with an RS800CX and it is a very large pulse meter with most of the functions that it has. But it had the complication of requiring a little more advanced knowledge for certain functions. The Smart Coach seems to solve this problem in part.

    I see a couple of issues that could improve the Polar V800 that other brands have in the same range.

    One is to be able to compete against your own realized brands.

    Another is the footprint analysis that the Garmin 920XT has.

    Implementing these two issues would be the ideal clock for me.

  4. Hello!
    A few days ago reading your post I decided to buy the V800 but I'm quite disappointed...
    -How come I can't see in the middle of a workout how far I'm going to get or calories or anything? -I paused. Something even the cheapest gps will allow you.
    -How come the automatic laptops don't allow you to see how far you've gone in the last lap and in manual if?
    -How is it possible that the light can only be switched on once training has started? -Cunt, it's night, I need light... wouldn't it be easy to let it go on before?
    I'm sorry about this will, but it just seems like such basic stuff...
    A salute.

    1. It is not the only one, in the current Garmin it also works the same way, in pause mode they only allow to continue or save the activity.

      I know the lapse issue has been reported. It doesn't really make much sense. Let's hope it doesn't take long to resolve.

      However, as soon as I have a chance to talk to Polar I will make a note of your incidents.

      1. Hello again,
        I'm sorry I spilled all this stuff on your page...but I decided to change my gps because of your analysis (gentlemen of POLAR, this guy is good, keep it in mind

        1. Don't worry, at no point did I take it personally or anything.

          It's normal that the change at first is hard for you, and that what you wanted to find in one place isn't there. It gets frustrating. I tell you, when I start with a new device, it takes me three days not to cancel an activity instead of pausing it!

          You'll see in a week's time when you're used to it, you'll start to appreciate the V800 more.

    2. Absolutely true. Think of the absurd details, such as not being able to access the altimeter or barometer unless you activate a workout, it's absurd. Or for example the absence of the track back, or the possibility of uploading routes to Flow... The worst thing is that they have made a device linked to an iPhone, as if those of us who buy this type of watch were running with our mobile. It seems that Polar has thrown in the towel and hopes that Apple will buy them and that's why they work for them (making it a mobile accessory). With a device like this the only thing left is to disappear in the face of competition.

  5. Hello, I have owned the V800 for some time but I can't find a way to follow a route that I have previously saved and marked in favorites, but I want to start it at a different point from the initial one. I would like to know if this is possible. I have written several times to Polar and I have not received a reply.
    Thank you

    1. Hi, John.

      No, at the moment you have no choice but to start a route from the beginning, you cannot start halfway.

      It is a bit strange, because in case you get lost, you do continue the route when you come back to it even if you jump part of it. But when you start, you must do it where you have marked the beginning obligatorily.

      Hopefully when Polar launches the 100% navigation for the V800 this will be checked, because it's not practical at all.

  6. Incredible analysis!! in the links you have left from amazon, when it says that it is used or second hand, it means that the packaging is wrong or that it has been used? is that I prefer it new but in the description it says the following and the discount is very good:
    "Packaging may be damaged. Minor defects on the top, front or sidewalls of the item. Minor defects on the back or bottom of the article."

    1. With that description, it's probably something used and returned for whatever reason. Those items usually come from returns. Sometimes it does say that it only has defects in the packaging, but with that description I'm afraid it will be a used watch

  7. Very, very good analysis. I can tell you've spent a lot of hours on it.

    I'm thinking of buying it, as I've had a bad experience with a Fenix 2. I'm very Garmin, even in my triathlon club they call me Garminman, but reading this review I found it to be a very good product, especially now with the latest updates.

    I am used to doing interval training, and these are very easy to do on the Garmin website. I think they are a nuisance at Polar, and it is not at all clear to me if they can be done on the Polar Flow website. I am referring to the typical series: warm up for 15 minutes and then 2x(10×200), that is 2 blocks of 10 series of 200 meters at full speed, for example.

    From what I've read, all the clock settings are done conveniently on the computer, and then the clock is synchronized, right?

    I'm also used to use Endomondo, Runtastic... which are 100% compatible with Garmin. One thing I didn't like about my Polar RC3 was that when I uploaded the gpx file to these webs, it only uploaded the route, but not the FC graphic. I had to put it manually. Is this still the case?

    Thank you very much!

    1. Hi, Valentine.

      Thank you for your words. Yes, that's for sure, hours have been many...

      As a triathlete, the biggest problem I see is the lack of a quick coupling kit. But if you come from a Fenix 2, it's clear that it's not going to affect you much.

      The Polar V800 has come a long way since its market launch. Unfortunately there are still things we are waiting for, mainly the open water swimming metrics, which continue to be delayed and are now announced for the second quarter of 2015.

      When it comes to programming training sessions, they have not yet reached the level of Garmin. The programming is a bit more complicated, as you have to make the selection by zones and it is not so straightforward. It can be done, but you need an "acclimatization" period.

      Yes, all the configuration is done directly from the computer, and on your next synchronization it will be on the clock.

      As for using Endomondo and so on, Polar Flow does not offer synchronization with other services at the moment, but you can do it manually. Anyway, if you have Android I recommend you to use SyncMyTracks, and you can do it automatically among all the services you want.

      If you're very Garmin, you should take a look at the Garmin 920xt. Today it is a more mature product. However, aesthetically and in terms of perceived quality, it is not up to par. But you can put a "quick release" on it.

      1. Thanks for the quick response.

        I know the 920, and while I like everything it does, I find its design horrible. It looks like a cheap watch, a tamagochi with a strap. That's why I valued the v800, because if it can be used as a quantifier bracelet, I would like to wear it all day and as a normal watch, the v800 is much more "wearable".

        There's also the Fenix 3, which is a 920 with a much better and nicer design, but like the V800 it doesn't have the quick kit.

        Doubts, doubts...

        1. Yes, if you want something for everyday use, the 920xt doesn't fit much to what you're looking for. In that case, the thing would be between V800, Fenix 3 or Suunto Ambit3, which also looks and feels very good although its activity monitor is quite basic (and in a few days, I'll publish the proof).

          Mind you, none of them have a kit.

          1. Thank you for your advice.

            I've already been accepted the Fenix 2 as a return and tomorrow I'm going to get the new one. I had thought about the Fenix 3, but there's a break in stock.

            Partly I'm in the mood for a big change, and the V800 catches my eye. The safe bet would be the 920xt, but if you let me take the V800 and in case I don't like it I can swap it for the 920 or the Fenix 3, I think I'll try the Polar.

            You'll see when they see me with a Polar. Garminman they call me in the club 🙂

          2. It's hard to get a Fenix 3 now. Too much demand for too few units.

            Good luck with your choice, whatever it is.

          3. The fenix3 is clearly superior to the V800, not only because of the battery but also because of details such as the fact that in low-cost GPS mode it doesn't even pick up speed, that the Heart touch is not useful since it doesn't allow you to dial a lap or that you don't even have the option to do a TRack Back, which you can do in Decathlon's reloges.
            By the way, Flow is not a beta (actually it's an alpha, it lacks an infinite number of basic functionalities).

  8. Very good analysis.
    I bought the v800 and when I set the altitude it doesn't stay memorized, I don't know why.
    and the compass I don't know how to put it no, I get to put it
    if you can tell me how I'd appreciate it.
    THANK YOU!!!

    1. The altimeter is barometric, it's based on atmospheric pressure and therefore depends on it. That's why you see these oscillations.

      The compass is only accessible when you are navigating a route, not from the main screen.

  9. Hi, I have a V800 polar fleece and I'm very happy. I haven't known for a few days why the watch can't find the pulse. My question is if the treadmill has to be synchronized with the watch and how can this be done. I've tried, but I can't find the way. When I go for a run and use the GPS, it estimates the calories, but if it's indoor exercise, impossible.
    Thanks in advance.

    1. The sensor battery is most likely dead. It carries a standard 2032 battery that you can find in any store or supermarket. You must open the sensor and replace the battery.

  10. Hello, good morning,
    Does anyone know in what conditions the polar bear warns you, when you pass the hour of inactivity, because I have spent more than 1 hour sitting and it does not warn. Is there a warning on the screen or sound?
    I've got it set to the polar to warn of inactivity.

    a greeting and thank you.

  11. Hello there,
    Does anyone know in what conditions the polar bear warns you, when you pass the hour of inactivity, because I have spent more than 1 hour sitting and it does not warn. Is there a warning on the screen or sound?
    I've got it set to the polar to warn of inactivity.

    a greeting and thank you.

    1. Polar has already updated the watch to include this feature. A notification will appear on the screen to warn you. But the watch also detects if the watch has not been worn, so if you have been very still and in a position that the watch can interpret as not having been at rest (0 movement and in a certain position), it may not warn you.

      But don't worry, with normal use and inactivity you'll end up seeing that message.

      1. Thank you very much for answering.
        What is curious is that when I set it up with android, I don't get the notification menu in the polar, but when I set it up with the one of the woman who is ios, it does.
        It won't have anything to do with the fact that my phone is android, and another thing the notifications have nothing to do with the inactivity alert.
        I don't think I have to take any of the tests before you tell me anything either, do I?

        Thanks a lot and sorry for so many doubts. I arrived yesterday and I'm a little lost. jj

  12. Hi Eduardo, I loved reading your V800 test, I don't think anyone has done a review as objective and good as yours.

    I'd also like to ask you a couple of questions. Look, I was sidelined from sport a long time ago due to injuries, and now that I'm finishing recovering and I've been told I can start doing (soft) sport, I want to do training with targets of carpal frequency zones; I'm sure I have no problem with the V800.

    Now, there go my doubts:

    Can I play sports by connecting the H7 band to the V800 at the same time as my iPhone? (I like to run while listening to music, but not always)

    Is there some kind of vibration warning if you leave the training zone in the V800?

    Thank you very much for your contribution!

    1. No, the H7 sensor can only be connected to one device at a time, that's the way Bluetooth works.

      The V800 has sound and vibration warnings, so when you're out of your programmed zone it will warn you without any problems.

      1. Hi, sorry to correct you but there is a way to do it with the H7 band. With the chest band on, you connect to the mobile and pair it with the application you are going to use (endomondo, cyclemeter, etc...) by bluetooth. That way you have the pulse in that application. Then you connect the V800 and it will receive the pulse by the 5 MHz band. That way the pulse will be shown and recorded in both devices. In the V800 the frequency value is shown in grey instead of black, to indicate that the band used is the 5MHz one and not the BLE one.

        1. You're more than forgiven, and you're absolutely right.

          That way you block the use of Bluetooth by the phone and leave the analog band for the watch.

          1. Curiously, in pre-training mode it only shows the pulse when the chosen profile is swimming (indicating that somehow this profile "blocks" the search for analog data from the band"), but even in the other sports, once you start training, the data is still displayed in gray. I find it very handy especially to have the data on the bike.

            By the way, congratulations on your analysis, great level of detail and the best I've read in English.

          2. Thank you.

            Yes, in swimming it appears directly because by default it searches in the analog band.

  13. Very good analysis, my most sincere congratulations for this website. One question, I am mainly a bicycle user, I would like to know if this watch marks the percentage of the rise, it is something indicative that is very helpful. Thank you very much.

    1. Thank you

      Yes, the V800 marks a percentage rise, but to display it the clock must be paired with a cycling sensor (from which it gets data for calculation). For example the Wahoo Blue SC which has a 20% discount right now, and is dual ANT+/Bluetooth

      1. Thank you, installing the polar will also get the percentage of the increase? apart from the cadence? could you pass me the link for the purchase in case I do it too? thanks again.

        1. Yes, with Polar's (which is this) you will also have the upload data. It also has a 20% discount.

          The difference with the Wahoo is that it only has Bluetooth connectivity, so you would be limiting yourself with expectations to the future, besides being slightly more expensive.

          But, today, they both meet your requirements.

          1. Thank you very much. A personal question, which device do you use as your own? Thank you again. Greetings.

          2. If I'm not trying anything (which is quite strange, I always wear 2 or 3 watches on my wrist) I use a Garmin Fenix 3.

  14. Hi, Eduardo. I got a v800 a few days ago, and I don't see the race time calculator on it like its little brother the M400. It can be implemented from polar flow?. Or there's no way you can do this on the v800?.
    For the rest, the polar is very complete. At the moment I'm very happy with it, it's great.

      1. Thank you very much for the clarification Eduardo. To be the top of the range polar should be incorporated this option also in the V800. It is not very normal that it does not have it. Anyway, we will hold out.

        1. Well, on the V800 you have the training target, which to all intents and purposes is like a virtual partner. It's like the timing calculator, but with one more lap. Personally I like that option better than the calculator, although I understand that if you are used to what the M400 offers you may miss it.

  15. Hi, Eduardo,

    First of all, thank you for this "great review", which as you can guess, I came across looking for information on multisport watches as I am in the phase of replacing my Nike+.
    Currently, I practice running and swimming, both in the pool and in open water, and naturally, with some duathlon already done.
    I've been looking at some reviews and the truth is that I think the V800 is a very nice design in front of the ambit 3 and fenix 3 that are the other candidates, but of course, in the end what counts is what each one can offer and what fits with each sport you practice.
    About the V800, I have some doubts:
    Do you know if there have been any recent updates that improve what you're saying about the open water issue?
    With the theme of crossings, I've noticed (I'm quite a novice) that the start forms a whistle of swimmers who stick their sticks all over the place. Do you think that the watch is consistent enough to withstand these blows? I'm telling you this because, for example, Suunto does look like it.

    Thank you in advance for your attention and if you could give me some advice to finish deciding, I appreciate it.

    1. Yes, Polar launched the open water swimming upgrade a couple of days ago. I haven't had a chance to test it, but I guess the performance will be comparable to the other manufacturers, hovering around a 10% error.

      I don't think you have a problem with tripping and pushing on the exits. I think if you get hit hard enough to break the watch, I might worry more about the wrist. In that sense the three watches you propose are pretty solid and with good construction materials.

      1. Hahahahaha!!!!! Okay, I hope I don't get hit with such a big blow, even though it looked like Cambodia at the Marnaton de Barna.

        Now I'm reading your other Suunto and Garmin reviews to finish making up my mind or to finish making out.

        Thank you very much.

  16. Hi, Eduardo,

    First of all let me show you my sincere respect for your work and your reviews, such elaborate work is greatly appreciated.

    I have the garmin 10 from a couple of years ago, which I use both on the flat and on the mountain on a bike and running, but lately I was thinking about switching to the Ambit3 sport or the Polar V800, and I finally decided on the latter. However, I have a doubt: I know that the H7 chest strap can be replaced by the Mio Link, and I was thinking of not buying the strap but the bracelet... am I missing something with the change? I say this because reading the review you did of the Mio Link I understand that it will be the same. I don't know if I am right...

    Very grateful!

    1. Thank you

      In the case of the Polar V800 it is interesting to buy it with the H7 sensor. Primarily because of the double capacity of Bluetooth and analog signal reception (allowing you to receive pulse data when you are in the water).

      In addition, you should be aware that algorithms based on pulse variability will not work correctly (training analysis, rest, fitness test, etc.) The basic pulse measurement function will do it perfectly.

      I recommend that you read this input on the optical pulse sensors, so you can understand everything perfectly.

  17. First of all, I want to congratulate you for the work you do with every review, and I've read a few.
    Secondly, I own a blue Polar V800 and I wanted to ask you a question and add a couple of impressions.
    The question is whether for more intensive use in mountain racing (including tracking) you see better Suunto Ambit or Garmin Fenix 3 than this one. The truth is that I'm not really interested in the swimming or cycling options (except for walking)
    And my points after 10 months of use.
    1. The software is a bit green, as you say. It syncs well with my iPhone app most of the time, although there are days with some time intervals that are not filled in despite having the clock on. Sometimes you have to sync it two or three times because, despite marking the synchronization as completed, it had not synchronized anything. Besides that, it lacks the ability to import activities from the old Polar Personal Trainer (something incomprehensible being from the same company) or from other platforms, except in a very uncomfortable manual mode (no route, of course)
    2. The quality of the materials is a little bit in doubt because, at least in the blue model, after 10 months of use, the condition of the strap is the same as in the photo. It is cracked, quite cracked in fact. The color was also the same as the one of the housing, but with the passing of time, in spite of being very similar, it has changed somewhat.

    1. Yes, the V800 is not a watch intended for use in the mountains, while both Ambit3 and Fenix 3 have been created with that concept in mind.

      The V800, despite being able to navigate, is still unusable in that respect as it is not even enabled to upload routes on a biennial basis.

      It's true that the software has flaws, but the truth is that it has been advancing at an important pace, but to focus on what it wants to highlight, which is a triathlon watch, and not a mountain watch.

  18. You're the pt master. It's an amazing analysis with detailed photos etc. Awesome. Well my question is:
    It is clear that I prefer the polar "BUT" I saw the garmin fenix 3 and I'm confused now I do not know which one can go better, since May I have almost daily workouts between 3 and 4 hours, I do ruming in street riding and gym, elliptical, maintenance, zumba and swimming, which of the two do you advise me, if you know the fenix this. Best regards
    If you can answer my email
    PS I will use your link when mr decides so you can continue with this amazing work you have done.

    1. Thank you for your message.

      For that use you indicate, the truth is that both watches will offer you very similar information. The difference lies above all if you want to track routes in your mountain routes, in which case the Fenix 3 would be the choice to make. You have the proof here

  19. Hi, good. One question. Since the last update (the one with the cadence) days ago, when I plan an interval workout, the v800 doesn't save me the series/times of those intervals. Only the manual laps. Does anyone else have them?
    I've been going through the settings but I can't find anything that has changed or at least I don't notice it.
    Any ideas? Or... just plug in and re-update firmware?
    Thanks for the help.

    1. It's a bug that has appeared in the latest version of the software. For the time being, the only thing you can do is wait for a new version that corrects the bug.

      1. Hello everyone, my thanks to the work done for this analysis, I just wanted to leave my opinion about how this heart rate monitor is made, with a cough my respects.
        Despite its good appearance, it is not designed to get wet and less in sea water, as what you see on the outside is plastic and steel, it has a chassis made of cast aluminum and other metals, which decomposes as the old batteries, ie sulfated, I say this because I have gutted mine and I have taken a good amount of rust, we'll see if it survives. I would not buy, despite the reputation of Polar that I think it does not deserve it.


        1. Javier, the watch is perfect. There was a series (the first to be made) with problems of swelling the battery that inflated the watch case. If you had sent it to the SAT they would have changed it for a new one. As it happened to me...

    1. No, to record a point of interest you must be at that point, it cannot be programmed in advance.

  20. Congratulations x the review, but after reading this one and the one you published about the garmin fenix 3, I have some doubts. I usually run and mtb, I've always used polar, right now I still use the rs800cx, but I've become infatuated with these models and I really don't know which one to take. Which one is better in your opinion?

    1. The V800 still doesn't allow you to load routes for navigation. Polar continues to promise that it will arrive, but it hasn't yet... Just for that reason and given the use of MTB you will be making, I think the Fenix 3 is more interesting. Also, the Garmin doesn't necessarily need the speed sensor to show the percentage of inclination.

      Anyway, take a look at the list of recommendations:

  21. Eduardo, a few questions:
    - Has Polaro already solved the problems in swimming?
    - Is it still necessary to buy a separate pedometer for running metrics without GPS, (on a treadmill inside the house, for example)?
    I say this because if I still need to go full of gadgets for poder treadmill running in winter, and in swimming still does not give metrics or anything. In the end when I finish buying all the accessories for Polar, (which also only serve me for Polar), it compensates me to pay the price difference between the Polar and Garmin 920XT, or even settle for a little less performance and buy a Suunto Ambit 3, (either the Peak or Sport), I mean for the practice of triathlon, duathlon, aquathlon, etc..
    Because I can see that the issue of charging you routes, is neither there nor expected.
    What do you think?
    Thank you very much in advance, and much encouragement to continue with the page, you are a reference.

    1. It will soon be upgraded to indoor stride metrics (the A360 already has it), outdoor is already up, as are the luxury swimming metrics. For this 2015 is expected onclinometer in running and download with third party route tracking. Bye!

      1. Thank you very much Miguel for the answer, I hadn't seen it yet, I'm still thinking about the renovation of the Timex.

      1. Hello Eduardo, thank you very much for your work and advice, I think you are the right person to solve my question: garmin fenix 3 or polar v800?The feeling that I have been given is that the garmin is much more complete, but it is a "tocho", to run I think it weighs and its round shape makes it dance, and for swimming I imagine it uncomfortable for heavy, (I've tried 24 hours) instead the polar v800 is elongated and lighter,I have tried it for 24 hours, but the polar v800 is longer and lighter, more comfortable, and much more attractive design, but I see that it lacks many prestacioness that makes the garmin is above, then I do not know which one to stay, what I do more are running races, pool, bike, mtb routes, cycle and indoor treadmill.hiking from time to time..... is it possible that with future updates the v800 will reach the fenix prestaviones in terms of basic metrics, I do not mean widgets and accessory things, I'm talking about basic measurements for training data such as inclination issue or that you measure kmts on treadmill or indoor bike, ?? in that case I'll keep the polar, otherwise I don't know what to do, right now I'm with the polar but I have 10 days to poder change it for the fenix 3, after payment of the difference of course, then what do you recommend me? that you use the fenix gives me think .... I think that a heart rate monitor above all must be comfortable because you spend many hours doing sport with it on, but I also think that not every day we invest a lot of money in a heart rate monitor and logically since we make the expense, we try to take the most innovative and complete.

        Thank you very much.

        1. By the way, can you put these heart rate monitors in the sauna without problems? And finally Eduardo, do you know if garmin is considering making a more social web for its users like suunto movescount or polar flow where you can "gossip" and locate other users on a map and see their stats ? That said, i luminame , greetings!

          1. I don't put my watches in the sauna, or it stays in the locker after swimming or I leave it outside with my glasses. Temperature changes are bad for any material and you can lose your resistance to immersion.

        2. As for weight I can't tell you much, I'm not a good reference. It is not uncommon for me to run with at least two watches on each wrist, so my concept of "weight" is very different than usual. You do notice the weight when you put the watch on for the first time, but it doesn't bother me when I'm doing sports.

          Advanced racing metrics are exclusive to Garmin, that will never make it to the V800. If indoor racing without a footpod is to be added, it is obviously impossible to record distances without sensors on an indoor bike, so they will still be needed.

          1. Thank you Eduardo, I appreciate your help, in the end I think I will not give him many laps and I'm going to stay with the v800, I like realmemte, what most threw me back especially were the problems that said in the pool but seem solved today, I'll keep reading to keep up to date, greetings.

  22. Hello Eduardo, I would like to know if the v800 has any function similar to the garmin live track, so you can follow in real time when I go out with the bike from a mobile, thanks, a greeting

  23. Hi. I just got the v800 in blue from Amazon. My question is can you turn off the daily activity?. As much as I'm looking, I can't get it... I managed to turn off the notifications.

    1. No, it is not possible to disable the activity monitor, but it does not result in increased battery usage.

  24. Thanks for the review. Important link saved in favorites.
    I am a user of Polar RS800 and I export the exercises to the website. In this Polar website there is an option to compare graphically several selected exercises. I find this option very interesting because it allows me to compare graphically the same route, for example, with different bikes (29″ vs 26″) or to see physical states by selecting the data you want to see (speed, rhythm, heart rate, etc). However, when I export the exercises to Polar Flow I can not find any similar option. Because the new products V800, M400, etc are incompatible with and I can not make use of this option, I ask you if you could recommend me some application compatible with Flow with similar function, and thanks to this, be able to buy a more advanced heart rate monitor. Thanks and a greeting.

    1. For activity analysis I recommend that you take a look at the GoldenCheetah software. It is free and VERY complete. Maybe too much. But you will be able to do that and much more, although you will need a learning period.

      You can also look at WK04, which is paid but a little more intuitive.

  25. Hi Eduardo. First of all, thanks for this review. Look, I have a problem. I was given a V800 with the H7 separately a month ago. Today I tried swimming mode for the first time in a heated indoor pool and the V800 does not detect the heart rate under water. If I got into the pool, standing up, pulled my chest out with the H7 sensor and licked the V800 out of the water, it did detect the rate. But just by diving a little, and standing up, the signal was lost. Swimming, even less. Is there an explanation and can it be solved, or is there just some technical problem with the devices and I have to complain to the seller?

    1. Are you sure that the sensor is the H7 and not the H6 (which has no analog connection), so you are indicating the problem is a failure of Bluetooth connection, at no time is connecting through the 5Khz analog band.

      1. You must start training in Swimming profile (if it is pool) to look for the frequency 5 khz. If you do not have the band properly adjusted the signal is lost. If the concentration of chlorine or salt is very high it makes it difficult to transfer. Remember to put the pool distance...

        1. Thanks to both of them. But as far as you are concerned, it is H7. And yes, I start my training in swimming profile with everything well configured. Standing up in the water it picks up the frequency but as soon as I dive and H7 is underwater, the signal goes away. I had read about the chlorine but I don't see it as logical because what gym pool doesn't have many chemicals for obvious reasons? But I have also tried it in my private pool at home just to get into the water and the same thing happens as in the gym and at home I have it with a very normal chlorine level. I am beginning to think that it is a factory defect of H7 because I don't think it is that the V800 doesn't receive the 5khz signal, don't you think? In another case I don't see that in swimming mode it has so many problems with the heart rate because it is a high-end product designed precisely to be able to swim with it. I also have problems with H7 in that it doesn't connect with the iPhone and therefore with the app
          What do you think? Thank you.

          1. Put down the App Polar Beat, connect the H7 on your chest, with this App you can deactivate/activate the 5 khz frequency sometimes, it disconnects (it's rare, but it happened to me once), if so, activate it again. I don't swim with a chest band, I use an elastic sleeveless shirt where the H7 is attached in some brackets, it's a Decathlon of their brand, and it never fails (you'll see that swimming the band is very unstable). It looks like you don't do well with the H7.

          2. It could be a battery problem. If the sensor has been in the shop a long time, it might be out of juice.

          3. Hello again. After trying everything I called the technical service of Polar. I was attended by a very nice guy and after explaining the problem, I discovered that as Miguel said the key was in the Polar Beat app. What happened is that I didn't even pod could access the H7 from that app and I didn't know why, nor how to check if the gymlink connection was activated. The explanation was that with the Polar apps, flow and beat, you can't directly connect the devices (the v800, the H7, the running sensor...) through the iPhone's Bluetooth. Let me explain: you have to activate the iPhone's Bluetooth but in the phone's "settings", "Bluetooth", you don't have to pair the devices with the phone. What you have to do is to open the app, and it is directly the app, not the phone, which links with the devices. Then it detects the H7 and the H7 options appear in the app and there I could see that Gymlink was not activated. I activated it and the problem was solved, finally!
            Apart from that, through the Polar flow app I linked in the same way the V800 that was not fully activated and from the app (not from the V800) I activated the "notifications" that until then I had not been able to get them to work either and, indeed, they work! They are not activated from "settings" "notifications" of the phone because the iPhone does not recognize in its "notifications" any of the two apps. Directly from the Polar flow app.
            So, thanks to the call to the service and the nice guy who answered it, it's all sorted out. Very happy with my V800.
            Thanks to Eduardo and Miguel for your help. Best regards.

  26. Hello, very complete analysis, I just need to know one thing, do you have like your little brother, the M400, the end time calculator for a running test? I think it is a very useful tool and I would like to know if it is available in the V800. Thank you very much!

    1. What the V800 has is the race pace, which is essentially something like that, but it's not the end time estimation function like the M400.

  27. Hi Eduardo, I have a question regarding the planning of workouts at Polar Flow.
    When creating sets for indoor pools, is it possible to assign them a specific name, for example, that set 1 is called "crawl", set 2 is called "foot crawl", etc., so that I know which style I have to execute at any given moment? Other than the typical predefined "warm up", "work", "cool down".
    Great analysis, by the way.
    Thank you!

  28. Eduardo, you know so much, I have checked the manual of the polar V800 and I can't find basic indications to use the stopwatch. Can you give me some elementary indications?

      1. If you do not have the Lap Time options set in the training screen of the sport profile, the Lap Time options marked with the Start button will not be displayed.

        Within the training press pause (Back button) and then two seconds (Light button) you access the training menu, where you can see the option of timer to time manual intervals without registering Lap.

        I recommend that you schedule interval training.


        1. I also have problems using the timer, I don't know how to set it to 0 and it goes to register 33 in the two or three times I've used it, the start and back button is clear, but how do you set it to 0 without it accumulating records every time you use it? I'm talking about using the timer outside the training mode

  29. Hello
    First of all, congratulations on the review.
    I've gone from Decathlon's cheapest heart rate monitor to this marvel of a V800.
    At the moment I'm delighted.
    I bought it from Amazon through your link

      1. Great review as it helped me to choose and change my garmin 405. Question, I would need for example to make passes of 200 mts with 20 seconds pause, the issue is that when I mark the lap, and I pause the watch stops the automatic stopwatch. and I can not see the 20 sec, unless I turn in circles so it does not stop... Is something that can not be modified or I come half hard with the manual. Greetings from Arg...abrazo

  30. First of all I want to say that I love all your tests, I think I read them all. After buying the Garmin 235 at through a link that you put in the BackFriday and that I returned because the optical pulsometer was too inaccurate, I want to buy another one. I was decided to buy the 630 but after reading the test and seeing offers of the V800, cheaper than the Garmin, I doubt if it is worth a watch that I won't take advantage of or if it will become obsolete soon. I don't do triathlons, mainly running and mtb and pool sporadically. Thank you.

    1. As a running watch, Garmin offers more data and algorithms. I would only go for the Polar if swimming is going to be a frequent occurrence or if you value navigation.

  31. Good afternoon, Eduardo,

    I just wanted to acknowledge the great work done on this article.
    I came in looking for a simple explanation of how to use the triathlon mode and I read the whole page.

    A salute!

  32. Good morning: what would you recommend me if we compare it with the V800? polar, with the garmin the budget goes up, but there is a lot of difference?, I am essentially looking for it to register well the swimming in the pool. Currently I have a M400 polar that for the rest goes in luxury. Thanks, your work is very useful.

    1. Take a look at the Suunto announced a couple of days ago. You have the article on the main page. It's a great option.

      1. Thank you very much Eduardo. I had already read your magnificent review. It was to know your personal option since you have tried the v800 and if it was more worthwhile. They let me try the new spartan in a shop...and it was either broken...or for being tactile...or for whatever...but it didn't register the swimming. It didn't measure...etc. That's why I bothered you since I read and trusted you. Thank you.

  33. Hello Eduardo, for the practice of trail running forgetting the tracking of routes or navigation and prioritizing training where the measurement and analysis of heart rate is essential, this polar v800 is worth ?

    1. If navigation is secondary, you're not asking for excessive performance, as you're really looking for very basic functions. The V800 and many others will serve you perfectly.

  34. Hi, Eduardo! I like your reviews, always very complete and detailed! Congratulations! I wanted to ask you if with the latest updates you can follow routes/tracks with the Polar V800, I think I saw the other day an update that even warns you with a vibration when you leave the track you are following. Is that so? Or do you still not recommend this watch for hiking?

    And another thing, is it true that the batteries of the models with blue strap are more resistant than the models with black strap? or was it a punctual defect that is already fixed? I consider buying a second hand one, with little use but that is almost two years old.

    Greetings and thank you!

    1. Yes, in the latest versions the navigation is more complete and it already allows you to upload your own routes. I haven't tested it thoroughly in its latest versions, but it's not like in the beginning anymore.

      Some units from years ago had battery problems, regardless of the color of the clock. But it used to be a failure that manifested itself soon, so if it's held out for two years I don't think it's affected. Anyway, on the eve of Black Friday, I would wait and get a new unit, I'm sure there'll be an offer and I'll go by putting over here.

      1. Hello again! Thank you very much for your quick response! Do you think there will be a deal for the Polar V800? Even though there are discounts, I think that by buying second hand you save about 100 Euros or a little more.

  35. Hi Eduardo. I've had the v800 for a while but now it gives me problems because synchronizing it on the polar flow doesn't charge my workouts. Do you know of anyone with the same problem and solutions to it? I synchronize the watch with the mac with the charger and nothing.
    Greetings and thanks

  36. today when i started training i went to choose the activity and when i was passing profiles it stopped running and it didn't respond to the touch of the up or down navigation buttons. so it took an hour, an error message came out and it went to the initialization screen and it's been there all day. i try to restart by hitting the 4 buttons but it doesn't respond. does this incident ring a bell?

  37. Good morning Eduardo, after the multiple updates of this polar v800 and being a practically closed and reliable product, prioritizing trail running, between this and the ambit3vertical, which do you prefer?

    1. If you are going to practice mainly trail my recommendation is the Ambit3. The Polar V800 would be a better choice for triathlon.

  38. Hi Eduardo, as a Polar fan, I've loved all your reviews.
    On the V800, I have for 10 years an AXN500 (before the GPS era) with a barometric altimeter with which for trekking I took a precise altitude curve - FC, and now I miss an Outdoor range that Polar abandoned years ago, for altitude measurements via GPS that the truth...
    I am reluctant to leave Polar because I have 10 years of my sporting life now in Polar Flow imported from the ProTrainer, and also for months now, I have had the activity and training with the A370, which is actually very good, since running is not among my sports.
    But for the (few) times outdoors, the M430 is missing an altimeter, and the V800 has too much and no 24/7 HR-based activity on the wrist, which my simple A370 or the M430 already has.
    So months later I'm still trekking with the AXN, passing the recording to the Polar proTrainer and from there to the Polar Flow, but that recording is not taken into account in the daily activity.
    What do you recommend? Thank you.

    1. The V800 is the only Polar with an altimeter. This year, in theory, its replacement will come out of which nothing is known yet. But if you want Polar and altimeter, there's nothing else.

  39. Good afternoon Eduardo and congratulations for your website, I have just been given a Polar V800 and it's going great but as a potentiometer I have the BePro that as you know they emit in Ant+ while the V800 works with Bluetooh.
    I've been "poking around" on the internet and I've found the Viiiiva heart rate monitor transmitter tape that in addition to recording the pulse seems to serve as a "bridge" to convert the Ant+ signal to Blueetoh receivers.
    I would be grateful if you could let me know if you have information about the usefulness of this emitter and if you know if it is compatible with the V800.
    Thank you very much for your attention.

    1. Yes, I have the 4iiii Viiiiva. I have not specifically tested it with the V800, but there should be no problem. I have used it with other devices successfully.

  40. good day, excellent analysis of all components, very detailed, comparing other sites that only detail the content of the device in terms of comparison with the garmin forerruner 645, which would you stay? and because, in prices I see quite similar in Argentina

  41. Good evening, I would like to know up to what year the polar V800 watch was manufactured, thank you.

  42. Good evening, I would like to know: Until what year was the Polar V800 watch manufactured, thank you.
