Polar Grit X | Full in-depth review and opinion

Polar is currently announcing the new Polar Grit X, its latest watch that the prepared to enter a segment in which until now they had no specific presence. This Grit X is focused to enter the outdoor range, the same in which we can find the Garmin Fenix 6, Suunto 9or APEX Pro Choirs.

The Polar Grit X is very similar to the Polar Vantage V, with which it shares most of its specifications. But remember that the Vantage V is above all a triathlon or running watch, and although it has a barometric altimeter and basic navigation, it was not intended for a specific use in the outdoors or mountains.

There are some changes in its aesthetics. The Vantage V is a watch with elegant and discreet lines, while the Polar Grit X is somewhat more “rough” in its design, but not in a derogatory sense. Polar has tried to give it a stronger and more vigorous look.

So, if the Polar Grit X is almost a variant of the Vantage V... are they the same watch with different aesthetics? Almost, but no. The main difference is in the specific functions that Polar has endowed the Grit X to be used in the mountains.

Polar Grit X, specs

Therefore, the comparison is established directly with respect to Vantage V, because it is the model that we all know and to which we can relate the new product. There are many features that are shared between the two:

  • The size is very similar . The Polar Grit X is 1mm wider than the Vantage V (47mm by 46mm of the latter), but it is simply a difference in the design of the watch.
  • The weight, in the same way, is practically identical. 64 grams of the Grit X by 66 grams of the Vantage V, finding the difference on the strap.
  • The screen is transflective , touch controlled and with Gorilla Glass lens. With a size of 1.2″ it has a resolution of 240×240 pixels.
  • The watch case is made of stainless steel, while the back is made of polymer (plastic).
  • Compatible with GPS, GLONASS, Galileo, BeiDouand QZSS. Of course, the GNSS chipset is Sony's.
  • It can be paired exclusively with Bluetooth sensors. Although all current Polar sensors are dual ANT+/Bluetooth, so far that duality has not reached the watches.
  • Meets MIL-STD-810Gmilitary durability standards. Vantage V does so.
  • All Polar's own performance metrics: Training Load Pro, Sleep Plus Stages, Nightly Recharge and FitSpark. Meanwhile Recovery Pro is only available on Vantage V.
  • Running power on the wrist without the need for external accessories.
  • Barometric altimeter.
  • Supports Live Strava Segments .
  • Polar Precision Prime optical heart rate sensor, although slightly redesigned.

These characteristics are the same in both models. Among all of them stand out all the training algorithms from Polar, which, together with running power, are undoubtedly the most important part of their product not only because of the information they offer but primarily because of how they all relate to each other. I give you a brief summary of what each one of them offers

Training Load Pro
Cumulative measurement of training load over time.

Sleep Plus Stages
Analysis of the different sleep phases.

Nightly Recharge
Beyond the sleep phases, it tells us whether the rest has served to recharge energy.

FitSpark
Recommended workouts for each day based on load values of previous days, our night rest and the general state of fatigue.

However, there is one omission, and it is Recovery Pro. It is an assessment that indicates how you have recovered from the previous day's training and confirms whether you can increase volume and intensity or it is better to make a more relaxed session. It is not present in the Grit X and is therefore reserved for Vantage V, although the reality is that Nightly Recharge can offer very similar information.

What are the specific features and functions of Polar Grit X? They are the following:

  • Hill Splitter, automatic hill detection during training to separate that part and give specific information, both during training and for further analysis later in Polar Flow.
  • FuelWise, an intelligent assistant that will give youhydration and nutritionrecommendations during longer outings. Alerts may be automatic or manual.
  • Possibility to create navigation routes with Komoot.
  • Current weather and weather forecast for the next two days.
  • Magnetic compass.
  • The battery has a little more capacity , going from the 320mAh of the Vantage V to the 346mAh of the Polar Grit X. However, the battery life announced is the same in both cases: up to 40 hours of use with GPS and OHR at maximum accuracy (every second). There are other battery saving options, allowing you to reach up to 100 hours of battery life by lowering the accuracy of the GPS or disabling the sensor.
  • Depending on the options we have selected for a specific sport profile, before starting the training we will have information about the maximum battery life for our activity.
  • The strap is 22mm wide, so we can use Polar's own or any other of that width. In the case of the Vantage V the strap was specific in the way in which the strap was anchored.

En definitiva, tenemos nuevas funciones destinadas a su uso en montaña y en salidas de trail.

The new Polar Grit X features in depth

Hill Splitter

Of the new features Polar has given to the Grit X, Hill Splitter is probably the most important of them.

Its function is to automatically separate the ups and downs that we encounter throughout our workout to be able to have detailed information about that section.

It is a kind of automatic lap, but instead of being activated by distance or time, it does so by rise or descent of 5/10/15 meters for a certain distance. It depends on the sport profile we are using; being 5 meters for running, walking or others on foot, 10 meters for cycling and cross-country skiing profiles and 15 meters for downhill profiles.

In addition to separating that part in the training file for further analysis in Polar Flow, the watch will also display a screen with the relevant data for that moment.

Polar Grit X - Hill Splitter

  1. Distance we've been going up or down. That is, the distance that has “that lap” until that moment.
  2. Total of meters we have been ascending on this climb. If it were a descent what we were doing, it would indicate the meters we were descending.
  3. Instant pace.
  4. The number of ups and downs we have been through. In the picture it indicates that we are on our first climb.

The screen does not have other variations and does not allow you to modify that data. Personally, I would have appreciated the ability to show power instead of instant pace, or at least be able to modify some of the data.

But just because it doesn't appear on this screen doesn't mean we can't check it on any other screen. It's still being an independent lap, so if on another screen we have selected the power or the automatic lap average we can also check it. And the same with any other lap metrics, it will be relevant for this particular segment.

This display is automatic and does not depend on any external function, such as loading a navigation route so that the watch knows when we are going to find a hill.

If you're familiar with Garmin, it's what in the Fenix is called “Auto Climb”. But Polar goes further because it doesn't just show the screen, but makes an annotation in the activity file, which allows us to analyze each of the hills after synchronizing our workout to Polar Flow.

But what it does not offer is information on how much we have to go up and how hard we have to face, since it does not have such cartography data.

FuelWise

FuelWise is the name given to the new hydration and nutrition assistant Polar has developed for the Grit X.

These are alerts to remind you when to drink and eat. The alerts can be manual, in the sense that you schedule the watch to remind you every X time what to drink and/or eat.

Polar Grit X - FuelWise

It also offers an automatic alert, and that is the interesting part, in which it is the watch that, depending on how the training is going, will tell you what to eat and when to do it.

To have these automatic alerts, before starting a workout you will have to tell the watch what you are going to do, because without that information it won't be able to show it. It's as if you're going to eat at your mum's house and don't tell her in advance that you'll be hungry after you've run 3 hours. If you don't want to stay hungry, you better warn in advance...

The information you need to provide is estimated duration of the workout, average intensity (for example training in Z3) and what is the amount of carbohydrates provided for each of the intakes (that is, look at the composition of the gel or bar and see how many HC contributes). This information is entered directly into the watch, in the “Fueling” menu.

Buscador de chollos

Based on the data you enter, FuelWise will tell you the total amount you will need for your workout. The calculation will be based on the data you know about your fitness and training history, which is what you have collected previously with the Training Load Pro feature. So when you go out to do your training you will know in advance how much water and gels or bars you will have to take, and also how many times it will alert you.

What if we entered that the intensity is going to be low, but the reality is that you start to compete with your training mates and increase the intensity? (Something that has never happened to anyone, has it?) FuelWise will vary the number of alerts and their frequency, constantly adapting to the actual energy consumption you are having. And the same if the intensity isn't as high as you thought.

Additionally, we will also be able to know what energy sources we have used in training, something that depends on the intensity of the exercise.

Polar Grit X - FuelWise

The watch will estimate the percentage of carbohydrates, proteins and fats, allowing you to know how it has affected you nutritionally and how to plan your recovery. This information will be on the watch at the end of the activity, but it will also be available in Polar Flow along with a graph showing the consumption by time of each of the energy sources.

Logically it is an estimate and not a laboratory test, although absolute data are not the important aspect but the relationship between them (more or less carbohydrates than fats, etc.).

This information will always be present, regardless of whether we are using FuelWise in the training session .

Komoot compatible

Komoot is a navigation service of an Austrian company, designed specifically for adventurous users. Polar relies on Komoot for the management of navigation routes because, unlike Garmin or Suunto, they do not have the possibility to create routes directly on their platform, it is only possible to import a route from Polar Flow.

The truth is that it is a very complete and easy to use platform, in which in addition to being able to create your routes you will also be able to see and navigate the routes that other users load on the platform. Let's say it's a social network of adventurers.

Thanks to the creation of Komoot routes we will be able to have turn-by-turn navigation, something that was not previously available in Polar.

Polar Grit X - navegación Komoot

As a platform that is not related to Polar, route management will have to be done through its website, and in your Polar Flow profile you will simply have to connect both services through the Partners section, exactly the same as if you were connecting your Strava account.

Polar Flow - Partners

The way Komoot works is by unlocking regions. As soon as you sign up for the platform, you can unlock the region of your next route. This first region is free and allows you to create unlimited routes in that area.

But if you want to use more regions, you'll have to unlock them. You can choose to unlock a province for €9, or unlock all regions with a single payment of €20.

Komoot - regiones

That would be all you need to enjoy that navigation with turn-by-turn alerts, you don't need to be subscribed to the Komoot Premium option but simply unlock the region or regions you're going to use.

There is no doubt that this partnership is very positive for Polar, as the aspect where the Vantage V has always failed most is in its route navigation. Not that a substantial jump is added (because there are no POIs or maps on the watch), but turn-by-turn is an essential element in any outdoor watch.

The Vantage V only offers route exit warning, and also does not have a magnetic compass. This one is available on the Grit X.

Polar Grit X - Magnetic Compass

In a watch to use while doing navigation that is a key aspect, as it allows you to stop at a fork along the way and identify which path you need to take to reach your destination. For GPS compass watches (such as the Vantage V), the direction will only be showed when we are moving, because the watch knows that we are moving from one point to another.

However, the magnetic compass does allow us to know which direction we are looking when we stand. Obviously it will not only help when navigating a route but also in any other circumstances where you need to make a basic orientation.

New Polar Precision Prime optical heart rate sensor

With the Polar Grit X we also see that Polar has made a small change in its optical sensor. The design remains unchanged, but what has changed is the number and color of the LEDs.

While in the original design of the sensor we had 9 LEDs (5 green, 4 red), Polar has now added one more and changed its color. In the Grit X sensor we have 5 red, 4 orange and 1 green.

Polar Precision Prime - Sensor

In the image above you can see both sensors and their distribution of the LEDs. As you see, the only thing that has changed is the number and color of them.

According to information provided by Polar, with the Grit X sensor and the color of the LEDs chosen, the impact of ambient light is reduced and the reliability of the reading is increased. Certainly something to consider for the complete test that I will perform soon, although for that I will have to be able to go outdoors first...

Polar Grit X, availability and price

Let's talk prices. How much is the new Polar Grit X going to cost you? Well, less than you thought. We are accustomed to the fact that with each new arrival of a product to the market, the brand will raise the price level of the previous model.

What is the pre-Grit X model? Well, there really isn't because, as I said, Polar is entering a segment where before their presence was practically testimonial. But why not think about the Vantage V... Let's say it is the basis of the Grit X, on which more features are added. And that Polar Vantage V has a price of 499€. Okay, maybe it's now cheaper.

If the VV “costs” €499 and the Grit X offers almost the same (only loses Recovery Pro) and more, then the logic says it should be more expensive, right?

Well, no, the Polar Grit X comes to the market with a price of 429€. Indeed, Polar has established a lower RRP than the one they marked at the time for Vantage V. The truth is, accustomed to the releases of other brands where each new model means adding €100 more to its price (indeed, we're thinking of the same brand that starts with a G and ends with an N), it's a relief to see that it doesn't have to be the usual.

We have three colors available: white, black and green.

Polar Grit X - Grupo

These straps are made of silicone, and together with the watch, Polar also launches a series of straps of different materials, designs and prices. The following options are available in textile, paracord and leather.

Polar Grit X - Correas

Prices range from 29€ for silicone strap to 49€ for leather strap, going through 39€ for textile straps.

The last thing you need to know is when you'll be able to get yours. You'll think that with the global pandemic situation we're experiencing, the presentation is just a shot into the air and that until everything pass, we won't be able to start thinking about it.

Well, that's not the case, because you can start reserving it right now and the first units will be delivered throughout May. In other words, availability is immediate.

Polar Grit X opinion

The entry of the Polar Grit X into the market is not a bomb that will shake the whole industry. It has news within the Polar platform, but these are things we had seen in the sector in a similar way. Hill Splitter and FuelWise had already been seen on other devices in a more or less similar way.

But remember, unlike when Polar launched the Vantage V, its platform is already much more mature and the Grit X comes to the market with all the features that the first Vantage lacked at first. Update 4.0 represented an important qualitative leap in what the Vantages offered, not only incorporating outstanding functions but also new features from the Ignite as Sleep Plus Stages and Nightly Recharge. And the 5.0 also brought FitSpark along with live Strava segments.

It is also necessary to add Polar Flow platform, in my opinion one of the easiest to understand that exist and that thanks to the Training Load Pro function allows you to see very quickly if you are overtraining. And let's not forget its battery life and the update of its optical heart rate sensor.

Beyond those functions, where I think Polar has been right is with the price. That will hurt the competition, offering a product with very similar performance, but at a fraction of its price.

That was precisely the success they achieved with the Polar M400, probably the most successful model for Polar and that triumphed because its price/performance ratio was superior to the rest of its segment. Success they want to repeat with the Grit X, but in a totally different segment.

Considering the watches focused on mountain or outdoor use you will only find cheaper the Suunto 9 in its basic version without barometric altimeter. But if we opt for the Suunto 9 Baro the price is already higher. The same applies to Garmin Fenix 5 Plus or Garmin Fenix 6 , which is higher than Polar has set for the Grit X. COROS APEX Pro is more expensive as well.

The price/performance ratio is a factor that we should never forget. The vast majority of buyers are not looking for the most expensive or the most complete, but what can best be adapted to their use for the least amount of money possible. And I sincerely believe that this is something Polar has achieved with his new model.

It just remains for me to place you for the full review I will make on the Polar Grit X in the near future, as soon as we can run outdoors.

If you have any questions left regarding Polar Grit X or want to tell us what you think of the new model of the Finnish brand, below you can find the comments and I will answer you as soon as possible.

And with that... thanks for reading!

  1. Gracias Eduardo, post muy completo.
    Veremos alguna de las novedades en el Vantage V? Me interesa sobre todo el tema de la navegación y la nutrición.
    Thank you

    1. Thank you, Juan.

      No, desgraciadamente ninguna de estas funciones van a llegar a otros modelos, son exclusivas (al menos de momento) del Grit X. Lo único que sí que hay es compatibilidad de Vantage V con Komoot para recibir rutas sincronizadas, pero no tendrá navegación con aviso de giro.

  2. Ahora sí, ahora Polar ha sacado un reloj que puede mirar de tú a tú a las grandes marcas del sector dentro de la montaña. Tiene una pinta estupenda, ahora a esperar tu veredicto tras la prueba!!

  3. Hi, Eduardo,
    Lo primero agradecerte los reviews que haces!
    Una pregunta, el Grit X tiene opcion de multisport? perfil de triatlon?
    Thank you

  4. Thanks for the analysis.

    Es una pena que no te faciliten un reloj para probarlo. Está YouTube lleno de gente que ya lo tiene para hacerle vídeos, y sin canales sin apenas suscriptores…

    1. No, I’ve asked Polar and nothing will go to the previous models. Furthermore, this is what we could read on Polar website after their latest 5.0 update: “The 5.0 is the final planned feature update”.

      So the Vantages will only be updated to develop its features even further, but not adding new ones.

  5. Gracias por la info, si no es por ti no conocía los detalles ya que no lo vi en la web.
    Saludos desde Mexico

  6. Hello, thanks for your great article. I think Polar integrated nice features, If I would not have my Vantage V, I would defintely want to buy this one.

    The only thing I wonder, is that you praise “Training load Pro”. In my opinion the most biggest bullshit ever implemented in a Polar product. It suggest that you have the same strain from training day D, in D+1 and D+5.

    1. Training Load Pro is very dependent on training intensity. So it “requires” some high Z3, Z4 or even Z5 training.

      When I did my Vantage review I was training for a marathon after an accident, so I had to do a lot of Z2 training. And sometimes it asked me to train more even when doing 60km per week.

      But with a more traditional training pattern I like how simple it is to read. For example Garmin does something similar, but it’s hidden under many submenus and it’s not as clear as Polars.

      1. I agree the beautiness of the display. It could be a really grat feature if they just adapt some serious math behind. It’s not as simple as: Trainingload last 7 days / 31 days.
        Trainingpeaks and Strava have some math that is making much more sense.
        (Note: I do not find my post if I chose “English”)

  7. Good morning, Eduardo,
    Sabes si tiene contador de calorías o algo similar y que piensas sobre las funciones de reloj inteligente, se acerca al SUUNTO 7 en ese aspecto o nada que ver?
    Muchas gracias por toda la información que publicas.

    1. Gracias Miquel.

      Sí, por supuesto, calorías es un dato fundamental de cualquier reloj.

      En cuanto a la parte inteligente es mucho más básico que el Suunto 7, sólo muestra notificaciones de mensajes, aplicaciones y llamadas pero nada más. Como cualquier otro reloj deportivo que no sea el Suunto 7.

      1. En cada notificación inteligente puedes interactuar con ella, si así está disponible en la aplicación de Android / iOS (por ejemplo: puedes llamar desde el reloj una llamada perdida y el teléfono llama, puedes controlar la música del móvil….)

  8. Hello!

    El reloj tiene muy buen aspecto, estaremos pendientes de cuando puedas publicar tu prueba…..
    Tu crees que debe tener cuenta kilometros totales? En algun modelo de polar no viene (m-430) y pienso que eso es un fallo de nivel porque es una referencia importante saber los kilometros acumulados que lleva un atleta en su temporada.

    Thank you, Eduardo!

    1. Por si ayuda. En el planificador de temporada de Polar flow, cada plan lleva un acumulado total del plan y semanal tanto de tiempo como distancia.

    2. Pues en ese caso, deduzco que los relojes modernos no llevan esos datos, que repito, pienso que són importantes. O solo polar? alguna marca si lleva km totales? Pensad en multitud de deportes (ciclismo, running, trail….) en los que saber el global de km. en una temporada es saber si la has cargado mucho o no y la puedes comparar con otros años…y no hará sumar!
      Grácias y felicidades por el trabajo, es de utilidad

  9. Estupendo preanálisis, mucho más completo que muchos análisis…
    Al Vantage V lo crujiían las críticas por la duración de la batería.
    Si la autonomía es la misma, ahora es un reloj de montaña / acampada , no puede ser que te tengas que llevar un panel solar.
    Cuánto ‘daño’ han hecho las pantallas táctiles, mi pulsera A370 al principio cargaba cada 3/4 días y a los dos años ya cada 1/2 días…
    A ver las primeras opiniones….
    Thank you

    1. Gracias Fernando.

      De momento llevo desde el martes con él en la muñeca. Unas 6 horas de entrenamientos y el reloj está al 26% en el sensor óptico y notificaciones durante el resto del día. Y con esa batería el reloj dice que tendría para correr unas 5 horas con uso de GPS y sensor óptico completo.

  10. How about Eduardo.
    Enhorabuena por el trabajo que haces macho. Tengo una consulta: Ayer recibi el Grit X., parece buen reloj,de calidad y completo para lo que yo necesito. Llevo viendo reviews de este reloj dos semanas….sacando toda la informacion posible y anoche en una review francesa, en un video, se veia como hacia lectura de las pulsaciones sin estar puesto en la muñeca, lo hace durante tres o cuatro minutos, en el mio tambien lo he podido constatar, y que al parecer altera los datos de las graficas de FC…eso es lo que decia el menda de la review….
    Crees que es normal? Aplicando el sentido comun, entiendo que lo que importa de verdad, es que cuando te lo pones haga su trabajo y te haga las mediciones oportunas no?
    Que opinas Eduardo?
    Pasa tambien en mas relojes de este tipo?
    No hago mas que darle vueltas tio…
