PolarGrit X Pro - GPS Multisport Smartwatch - Military Durability, Sapphire Glass, Wrist-Based Heart Rate, Long Battery Life, Navigation - Ideal for Outdoor Sports, Trail Running, Hiking, Black

TLDR: if you can get it under $450, nowadays is still a good watch for the price. I would like to give it 4.5 stars as it is close from 5 stars than it is from 4 stars for that price, but Amazon doesn't include that option.I've been using this watch for a couple of months now, and while I had some problems at the beginning, after a factory reset the watch has been behaving very well. It certainly doesn't have the latest and greatest tech such as dual-band GPS or maps for context when you're following a route, but to be honest these are things I don't really Its accuracy is very good for a single band GPS (I usually set it to use GPS and GLONASS as I do MTB every weekend) and I've found that sometimes it even returned better accuracy than my Wahoo ELEMNT ROAM, which has dual-band GPS. I remember once I had a bug in the ROAM where the route was not loading in the computer, I used the navigation from the watch and it was very usable. Sure it was less convenient for the watch position and the sport, but it can get you out of a pinch and the compass is accurate enough to even track MTB in the trails.That being said, a very noticeable thing for me as soon as I got it from the box was the weight: maybe I was spoiled from my previous watch which was very lightweight, a Polar Vantage M2, but the quality of the materials and the extra components are immediately noticeable as soon as you pick it. In your wrist, you get used to it after a few days of wearing it, however, you need to be more careful when tightening the strap when you sleep, as it can produce inaccurate readings, or even detect long periods of time as 'unrecognized' if you press your watch against your body, as the weight will make it slide and lose contact with your skin.When it comes to sports, despite you can get used to the watch weight, you can certainly feel it when you are making any bouncy sport, such as mountain biking, and you need to set it very tight to avoid the bouncing to affect the heart rate readings much. Whereas the strap itself is comfortable (more on that later) a tight watch may be uncomfortable no matter what, in my case I use an external heart rate sensor, so I can set the watch a little loose and still get accurate data; you will still feel the watch bouncing, but it won't hurt your wrist, your mileage may vary on that end.The strap is from FKM rubber and whereas I had the impression of being bulky in the videos, it is very sleek and probably the most comfortable strap I've tried, it is very breathable, and it dries very quickly. I like it and I would probably switch it just for style or color matching for some occasions. When it comes to durability, the watch has proven to be very durable, I've had a couple of crashes in my MTB with zero damage to the watch, I've hit the bezel once against a metal gate and the one who got the pain chipped was the gate lol, and I've been using it both outdoors doing MTB every weekend and in the gym without any physical marks either on the watch or the screen so far. Time will tell as two months it too little to judge, but it seems promising.Many people have commented about the screen brightness, but I've had no issues whatsoever either using it indoors or outdoors with the brightness set at low. It is dimmer than other mineral crystal displays, but that is a sapphire thing, and it is present in any sapphire crystal display in any watch. That aside, when I'm doing MTB and considering my handlebar is wide sometimes I don't even need to flick the wrist, sometimes I can get the HR by just glancing at it. In the gym I've noticed under the right lighting conditions the screen is not visible from an angle, but just moving your wrist a little makes it readable again and so far I don't find it annoying as I prefer that and having peace of mind with my screen not breaking easily or scratching at all, as I had to replace the screen protector in my previous watch every few months.I train between 8 and 12 hours a week in average, recording no GPS activities from Monday to Friday mainly being 45 minutes cardio sessions 5 times a week and three strength training sessions between 1 and 1.5 hours each and a long MTB ride on weekends for about 8 hours. With that usage I use to get between 5 and 6 days of battery life. It is not the most everlasting battery watch, but barely charging it once a week is good enough for me.When it comes to the touch screen, it surely is a nice to have feature, but it is not, by any stretch of the imagination, the best touch screen experience in any watch, let alone in any sports watch. The touch screen is disabled while doing sports, something I don't really mind. When it comes to everyday use, there is no back button gesture, which means you will have to rely on the physical button to do that, and that may be a small inconvenience to some. When you start interacting with the touch screen, there is a delay on the initial touch to the screen, which is slower to respond, and after the first interaction the consecutive interactions have a decent response time - for a sports watch - once you learn you need to tap and hold the screen for a fraction of a second with your first gesture and then proceed as normal, the touch is very usable, however, I can see that simple action can become very annoying for some people, and forgetting about it surely may turn the 'annoying' into a 'frustrating' experience. You get used to it after using it for a while; that being said, it should the watch the one to accommodate to the user needs, not the other way around.Nowadays for the original price, I think it's too expensive since the technology has advanced quite a bit, and it is missing features that have become normal in the industry, however, if you can get it under $450 I think even nowadays it is a good deal, I got mine for $430, but I've seen it even cheaper during some deals even here at Amazon. It is a good watch, and I am hoping to keep using it for the years to come.

Love this. I had an A:300 for years and the USB charging enclosure finally gave out. This newer model turned out to be an excellent replacement. The options and sync functionality are vastly improved.

Was lucky to get these on a really good deal and got this for my dad. He doesnt really buy too many watches so this is a good one he can beat up throughout his day. All he mentioned was that it lasts a long time and has big enough numbers (lol). Thanks dad

Great watch for all activities. The watch is better then Garmin and Fitbit.

Just incredible that a $500 watch can be essentially unusable in most outdoor situations especially if you actually need to read the seconds. The screen is so dim that even with the brightness setting at it's highest you'll still be squinting to see the screen outside and the seconds are so small that they are all but invisible in direct light. Also the backlight light only stays on for about 7 seconds so you're constantly having to shake you're wrist or hit the backlight button. I just returned a Garmin Instinct that was almost 1/3 of the cost and had a 100x better display.What a shame, it's a beautiful watch and I'm sure it's accurate but I'll never know because I returned it the same day I received it.

The watch is fantastic. The seller was quick!

Polar had at one time been the gold-standard for fitness wearables. While their accuracy for heartrate, steps taken, miles run, etc is still very high. The navigation of this device is not intuitive. Further it's VERY limited for those who like to log strength training. If you're into anything else besides running or hiking, get a Garmin.
