Great watch
Its very nice. The screen takes some getting used to, as compared to other backlit watches, when indoors it seems dull, but you get used to it. When you are outside in full sun is where the screen really shines. Its supposed to be like that for power saving. The battery lasts well over a week if you are not training a lot and about 5 days if you are training a lot. I am very happy with it.

Notifications issue
Everything find except push notifications, when you are using as smart watch the performance is not so we'll, or else fine.

At the beginning of the COVID lockdown I was fortunate enough to locate a good deal on a new Bowflex Max Trainer M5 on Amazon. But the chest strap HRM was crappy. I then got a Polar H10 HRM chest strap, which was awesome, and exposed me to the online Polar tracking software which is even more awesome. This then prompted me to get this Grit X watch where I could add sleep monitoring and have a more full view of my calorie exertion. For my needs was likely overkill, but wanted a fitness watch with an always on display, I was sold on the Polar ecosystem and this is just a darn good-looking watch. 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.
