My choice is Huawei Watch GT (FTN-B19). Why?
Their ideas are very different from the usual smartwatches such as Apple or Samsung, where you can install your applications, thus increasing the capabilities of the device. Huawei considered that giving such an opportunity does not make sense, since there are still no third-party programs for Lite OS, nor is the SDK for developers ready, it will appear later.
That is, you get exactly those functions that are in the watch initially or which the manufacturer will add later with updates, but you cannot change anything in them. For many buyers like me, this will be enough.
Huawei GT watches can show notifications from the phone, be a companion in sports (including GPS measurements and tracks). They can also be ordinary watches. Let's look at what these watches can do and how they work together. I like the fact that the watch is designed in a classic style. They are not as massive as the Galaxy Watch, they differ from the Apple Watch, as they look like a familiar watch.
The standard band is 20 mm, the same ones were used in previous watches from Huawei, it can be replaced with any standard one, whether metal or silicone. I advise you to choose the bands since otherwise you risk running into the fact that they look weird with the watch.
