The watch has been used for 7 years. Bought for outdoor activities and wearing in the summer. But gradually switched to permanent wearing. Very comfortable watch. The display is simple. Informative. After about 3 years, the battery ran down and the backlight stopped working. Carried another 3 years without backlight without changing the battery. About half a year ago I decided to replace the battery, after which the clock began to leak moisture. The watchmaker said that the cover gasket and the button gasket in the watch needed to be replaced, which are only available at an authorized service center. I didn't find it in the public domain. In the end, I just replaced the battery. Naturally, with old gaskets, the watch began to leak moisture. I decided to dry it in the bath, as a result of this experiment I killed the display. As a result, I was happy as an elephant for hours. I will take it again and next time (in 7 years) I will change the battery in the service center.
