Here are my favorite features of this watch
Optical HR sensor. It is extremely accurate. I ride my bike on a smart trainer 2-3 days a week during winter/spring, using the Zwift app. I have a Polar H9 heart rate strap paired to the Zwift app. I can pair this to the Grit X, but did not detect any delta between the HR strap and the optical. On both rides, at various intensities I never saw more than a 1-2 beat delta between the two. Very cool as I like to see my HR, but don’t like to always wear a strap while mountain biking.
Hill Splitter. This is a welcome feature for anyone that likes to do hill repeats. No input needed. It senses your ascent, and automatically counts your repeats for you as well as the distance and time of ascent and decent. This worked great two days ago on hill repeat workout on my road bike. This is fun and convenient feature.
Screen display and touch features. I like the new display. Very clear and just bright enough. Of course easy to light up with the top left button. I have it on the weather screen all the time. Nice to have winds and temperature right in view.
Route guidance. This was something I did not use a watch for until now, but very comfortable using now with the Grit X. I live in Bend Oregon where we have a plethora of trails to explore. If you want an effective way to find a prescribed route, this watch makes it very simple. You will easily stay on your trail/road and know when to turn.
Battery life. I did three loooooong workouts in 2 days, had the optical HR, GPS etc. on continuous and still had tons of juice remaining went to charge it.
I love all the other features such as swim metrics, sleep stages, and nightly recharge. Just started to use FitSpark and I’ll edit this review after I use it for a few weeks, but looks like another great training tool.
All in all this is another great watch from Polar. This watch can do it all and more than my other brand GPS bike computer. It is a personal coach/trainer on your wrist along with the Polar Flow app, and the durability of a G-Shock. I highly recommend this sport watch. 5 Stars.
After 3 weeks with this watch I'm very pleased. I like the extended battery life if I were to travel for work (but I have not been), but recharging the watch daily as I read my Polar Flow app takes about 15 minutes or less. I knew before buying this that the HRM function would not be as good as a chest strap. I use the chest strap for my HIIT training when it is important to get real-time results as I approach my heart beat max. The pairing of the watch and chest strap is automatic, look for the circle around the heart rate to turn from green to blue. But I take walks with my dog and longer walks with my wife and despite my living near a country border a block from a large lake my watch has had no issues tracking distance and mapping out routes I have taken. The sleep results seem to be pretty accurate as well. I like the watch face data options and I frequently keep it on the 3 hour weather forecast, which works well. While many have added the "COVID 15" I've actually lost over 15 pounds over the past 2 months. I'm in my 50's but my goal is to get back to my high school weight, so am looking to lose another 40 pounds over the next 9 months. For me, being old and overweight were 2 things I did not want when looking at COVID morbidity statistics, but now between my fitness and diet focus (which I had never done before) I really think I have created a very positive life style change for myself. I added some Barton quick release watch bands and they have worked real well and have added further watch versatility.
My priorities are:
1. Accurate GPS tracking and elevation
2. Battery Life (minimum 40 hours activity tracking)
3. Accurate Heart Rate
4. Lightweight & Durable
The Grit X excels in all of these categories. Its wrist based heart rate is the best I have experienced, and is tightly aligned with my chest strap measurements. The GPS tracking and elevation was flawless even when running in the Boulder foothills where many GPS units struggle due to the proximity to steep slabs and cliff faces. Battery life has proven to be excellent, and it is much lighter than all of its competitors with similar battery life. It is light enough that you do not experience any wrist bruising when riding technical mountain bike trails, yet durable enough to not be concerned about taking it on a fourth or fifth class scramble.
When you combine this with all of the standard Polar Heart Rate features, Hill Splitter, Fueling Reminders and Komoot Navigation support features, it is truly the product segment leader. You will be extremely pleased with your purchase of the Polar Grit X!
Do a lot of research (google, youtube )to find what kind of watch will suit you best. Even if you choose another brand you will glad for your time spent searching.

Relógio muito bom, resistente e bonito.
La boussole notamment qui est compatible avec Alltrails et Komoot est très pratique pour les randonnées pédestres, vélo de montagne et vélo de route.
La montre est très résistante, notamment la vitre qui est réellement military grade".
La fonction "Serene" est intéressante pour planifier des moments de relaxation.
Finalement, la prise pour le pouls est assez précise pour m'indiquer mon niveau d'effort en cours.
Seul bémol, durée d'autonomie de la pile. Si vous sollicitez régulièrement les différentes fonctions pour vos activités, vous devrez vous attendre à recharger la pile aux 3-4 jours. Ceci dit, le temps de chargement est assez court (environ 30 minutes pour une pile presque complètement à plat).
Je rachèterais ce produit sans hésiter.
Ik draag heb nu enkele weken en gebruik hem intensief met sporten ( Fitness en wintersport ). Daar registreert hij alles goed van. Samen met de Polar app kun je alles analyseren van je workout.
Als horloge en sieraad ook mooi en functioneel. Ik ben er blij mee en zou hem zeker aanraden.
Alleen lastig installeren in het begin, daarna is hij top.
