Design, ergonomics

The main feature of the body of this model is,Of course, full protection from moisture and dust. That is, these watches are not afraid of water at all, I do not think that an ordinary user will dive deeper than ten meters, but this is how much the device withstands for half an hour. The build quality is appropriate, no gaps, linings and squeaks, the water keeps really, the tests were carried out. However, immediately after bathing, it is better to dry the device, wipe it, and you should not put a bracelet in the sauna, because two aggressive factors can destroy anything at once.

The module (mechanism) is detached from thebracelet, and in the removed state looks funny and somehow too slightly. Probably, because it is very light, only 25 grams with a thickness of 10 millimeters and dimensions of 41x24 millimeters. The screen and the panel of silver are checked as a sensor control unit. Once we press - the display is turned on, the second we press - the transitions in the menu have gone, we hold down for a couple of seconds - the submenu has gone. Actually, the management features end there, there are no physical buttons here. Navigation is as simple as possible, get used to without problems.
