Español A fairly common gesture among runners is that when it's time to run, they take off their usual watch from their wrist to put on their specific GPS watch to go out and train. GPS watches for running or multi-sport have usually been flashy, one might even say crude and ugly.
So Polar wants to put an end to all this. The Finns are determined that your training clock can become your everyday watchThis formula that started with your V800 model has now reached the mid-range.
The Polar M400 not only will it record your routes, informing you of times, rhythms and heart rates, it will also keep a daily record of your activity, counting steps and calories consumed, and at night it can monitor your sleeping patterns. It will even warn you if you have not moved for a long time.
All training done with the watch, both running and activity monitor outputs, will be synchronized with the Polar Flow portal. The Polar M400 has Bluetooth Smart 4.0 connectivity, allowing it to be connected to supported mobile phones. The connection to the phone will allow you to plan workouts, set up training zones based on the heart rate and review our races, all from a screen larger and more comfortable than that of a watch. If you do not have a phone with Bluetooth 4.0 you will not have a problem, as it also supports USB connection, with a micro USB connector that will also serve to charge the watch.
The Polar M400 It is also waterproof, up to 30m. However, being submerged it will not register the heart activity, as the bluetooth transmission is not able to work under water. But it will be useful to the triathletes, who will be able to use it from the start. As for the autonomy, it is 8 hours in use with GPS and up to 3 weeks if used as a watch and activity monitor.
In the future, compatibility with the step sensorThe speed sensor is not a standard feature of the bike, but although it is also designed for cycling, it does not support the connection of speed/cadence sensors.
Polar M400. Availability and price. When can you buy it?
This clock is expected to arrive in stores throughout the month of OctoberYou can buy it at a price of 160 ? for the version without heart rate transmitter, while if you want to buy the kit the brand will offer it for 200 ? including the model Polar H7 HRA price that is frankly competitive and that will surely make the competition revise its product catalogue.
Hello,
It's been a while since this gps watch has been on the market and therefore it's already in stock without a problem. If you had to choose one of these gadgets for running only, would you choose this one, the Garmin fr220, or any other "cover"?
I see a downside to the lack of vibration compared to others, how do you see it?
A salute.
Hi, Fonty.
I am finishing the test of the Polar V800, so I will soon have the opportunity (and time) to get into the M400, but you will be able to read the full test of the V800 in one or two days because when it comes to running, the performance is very similar.
As for the M400, it's a real shame it doesn't have vibrating warnings. I don't really understand it, because the warnings are not very strong.
Probably, as a watch exclusively for racing on asphalt, I'm more inclined to go for the Garmin 220, precisely because of the vibration. For me it's an important feature. In addition, the training targets are more varied than on the M400, which can only select one heart zone as a target.
However, I think that the Polar M400 is above the Garmin 220 in some aspects, such as the menu, the quality of the display, the 24h activity monitor or the aesthetics, if you think about using the watch every day.
Difficult decision, no doubt. In the end, if vibration is a very important feature for you, you should choose the Garmin 220.
As for the other cover, the Suunto Ambit 2 is now quite low in price, with the release of the Ambit 3. But keep in mind that it also doesn't have a vibration warning. And of course, the Garmin 310XT, which has everything at a very good price.
Greetings
I will be listening to your opinions in the V800 and according to the feelings in the running section I will decide.
The truth is I had almost decided to go for the Garmin 220 but that price you put on Amazon is really tempting.
That said, I'm waiting for your post.
A salute!
Well, you're ready to test the Polar V800. You can find it here: https://www.correrunamaraton.com/polar-v800-review/
I hope you like it!
Fonty, I'm sure you'll be interested. Right now you have the M400 in stock at Amazon at 119 http://t.co/0kryXlmBgb
And the pack with pulse sensor at 149 euros, although it appears out of stock, but they will surely add it soon: http://t.co/EdGrv5gdaI

Good morning, I have a polar m400 for less than a month. My question is because it used to work perfectly but since two days ago I can't get it to synchronize with my mobile app or with my computer (it tells me that the activity data is not synchronized). Would you know what this could be and how to solve it?
Thanks in advance!
Greetings
Polar Flow has been down for a few days, it's a problem with the Polar servers, so all you can do is be patient and wait for them to fix the issue.
