The US-based company Garmin’s newest multi-sports watch is the Fenix 7, which is a crown jewel in the Fenix line. Garmin Fenix Series watches are popular with athletes and people who like to be outside. They are known for being tough and durable and having a lot of performance and health metrics. The price tag on these watches is pretty high.
Polar Grit X Pro, on the other hand, is the newest product from the Finnish company Polar. It is a step up from the Vantage V and M, which are already very popular. The Grit X Pro is a tough sports watch with GPS and built-in features for training and rest. If you’re looking for a comparison between the Garmin Fenix 7 and the Polar Grit X Pro, you’re probably looking for a high-end sports watch that can do a lot in the outdoors.

Polar Grit X Pro vs Garmin Fenix 7: Battery Performance
When choosing a sports watch, this is one of the most important things to think about. You don’t want your watch to stop working in the middle of a workout or race. In training mode, with GPS and an optical heart rate sensor turned on, the Polar Grit X Pro can run for up to 40 hours on a single charge.
If you turn off the heart rate sensor, the battery life extends up to 100 hours. In GPS mode, the Fenix 7 can last up to 57 hours, and the standard model can last up to 18 days. Even though battery life varies from model to model, Garmin watches in general have better battery life. You can buy this smartwatch from its official website
Polar Grit X Pro vs Garmin Fenix 7: Smartwatch features

The Garmin Fenix 7 has all the sensors you’d expect from a high-end smartwatch, like the company’s latest generation Elevate 4 optical heart rate monitor, altimeter, compass, SpO2 (blood oxygen) sensor, and temperature sensor.
SpO2 monitoring can happen all the time, just at certain times, or overnight. The Garmin Fenix 6 just got a firmware update that warns you if you move your wrist too much while the watch is taking a SpO2 reading. The Fenix 7 has the same feature. It has the best sports tracking and data analysis that Polar has to offer. With more navigation features, it’s also a better outdoor watch.
The big question is whether or not it is a big enough improvement over the first Grit X. Are the Vantage V2’s new navigation features, extra performance and recovery tests, and sleeker, more durable design enough to make it worth the extra money over its predecessor, especially since some of these new features will also be on the Grit X.
Which one should you buy?
Even though the Garmin Fenix 7 stands out, there is no one watch that is better than the others. It depends on what you want to do and what tools you need. These top-of-the-line outdoor watches have different and sometimes complementary benefits: with or without cartography, with more or less advanced features (sports functions, GPS navigation, connected functions).
The Fenix 7 has the most features and will appeal to athletes, competitors, and fans of numbers who are picky. Instead of Coros’ Vertix 2, it is also our favourite mapping programme. It stands out because it has a lot of features and tools, advanced connected features for everyday use, and a lot of models and straps to choose from.

FAQs
How accurate is the Fenix 7 heart rate monitor?
The accuracy is more than enough for my needs. The heart rate sensor works very well in a second test on a speed mountain tour. Aside from the first few metres to warm up, the values measured by the fenix 7X’s internal sensor match the heart rate monitor strap very well.
Can Garmin Fenix 7 answer calls?
When your connected phone gets a call, the fnix® watch shows you the caller’s name or phone number. NOTE: You must use your connected phone to talk to the caller. Select Reply and choose a message from the list to turn down the call and send a text message right away.
