It’s a nice watch. I own pieces from other brands, and I stopped wearing this one for about a month; when I decided to put it back on, it was still running. I found this odd, since it’s supposed to be an automatic watch—meaning you need to wear it to keep it wound and functioning—and it supposedly doesn't use a battery. Another thing: every time I wash my hands, water gets inside the watch, even though it’s rated for a depth of 30 meters. I have my doubts as to whether it’s truly an automatic or not. Does anyone else here own one?
