- Cool work of fitness features. This includes everything from workout tracking to step tracking and heart rate monitoring, everything works great. Graphs can be plotted for each parameter
- Waterproof: I do it in the pool, no problem
- Battery: quietly hold 4-6 days
- Screen: perfectly visible in daylight without backlighting, if there is not enough lighting, the backlighting is also very bright - set to 10%, enough "for the eyes". When set to full, you can use it as a weak flashlight (this functionality is even available in the watch)
- Notifications and calls: everything is fine, I have never noticed that some message was "undelivered" to the device. Moreover, I was pleased with the additional functionality (see comment)
- Appearance and the possibility of independent replacement of straps. The size of a regular watch, absolutely no weight is felt. I bought the "black and white" version, they look great. I bought a replacement strap on Ali for 300r - they began to look like an ordinary classic watch. The strap is the usual 20mm, the watch immediately has a quick release, that is, when buying with this, you can change the strap yourself at home in 30 seconds. So I do when I go to the pool - I change to silicone.
- Integration with the calendar. You can set it up, and events from the calendar will be stored in the watch itself, so the current schedule will be at hand, even if the connection to the device is suddenly lost.
- A separate point about training: training can be done by leaving the phone at home, they will then be pulled up automatically. There are a huge number of types of classes, plus you can add some specific ones. You can independently compose a workout with time intervals (alas, only with a PC) - for example, 5 minutes of running, 30 seconds of rest, etc. Tracked cool - that running (both a pedometer and GPS helps), that swimming (determines the number of strokes, their frequency, by pushes from the side determines the pools, with the entered size of the pool writes the swim distance)
