Since I am water sports, I go for some time with these watches. The functions are sufficient, the clock is easy to use. In the water, I have never had a problem with these watches. However, two watches me have already gone broke in mountaineering. So from about 2000m and rain, or high humidity are the watches no longer close (presumably the lower external pressure). It then has moisture accumulated in the watches, which has led to the failure of the watches. The watches were At this time, several years old, perhaps also plays a role?
