    I like it
    Color: grey, Color: grey
    It’s not expensive but well made. The tack thing doesn’t spin. Idea for daily wear with a nice look to it. I gave it a 4 because the tact thing doesn’t spin and I like a larger watch face. All in all I may buy more as fashion watches for daily use.

    Not water resistant
    Color: silver black, Color: silver black
    Have had it less than a month, shower and swim with watch on. Water is under the face. Very disappointed in the quality, I get it is a relatively cheap watch, but quality should be better than this. Will never buy again.

    Water is getting into the watch.
    Color: silver white
    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?
