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?

I absolutely love these watches! They are built like a tank. They can take a lot of abuse and still keep great time. I originally was going to buy just one to replace my old watch. Ended up buying several of them. Great gifts. The watches are beautiful and elegant, and I feel like a thief when I buy them because the price is so low I think its a typo. I have gotten several compliments on them when I wear them. I have busted up concrete and cleared heavy terrain ,cleaning areas out, wipe then off and they look Like I just took them out of the box. The only thing, and it's not a big deal to me.But the glow in the dark arms don't last long. They even give you the tool to adjust the wristband. Who does that🤣 The Quality of these watches are phenomenal
