    it looks fantastic. There is nothing humble about this watch
    Color: A Gold
    It is a steal for the money, it looks fantastic. There is nothing humble about this watch. It makes its presence known. I see people get sight of it, then look away and come back and take a second long look at it One thing I would change.. the hands are not easily seen because they blend too much with the back ground. I got used to that and does not bother me any. Louie Vazquez in San Antonio TX

    DOA - doesn't work.
    Color: A Gold
    Love the looks of this watch but I cannot get it to work. I think that it is mechanical, but I wind it and it only runs for one to 10 minutes and sometimes not at all. Am I doing something wrong?

    nice watch but expect what you pay for.
    Color: A Gold, Color: A Gold
    Pretty solid watch decent size face i prefer large face watches even with my small wrist. Its pretty good at staying synchronized. The case is pretty solid but closer inspection makes it look cheap, i still love though and it does get a lot of looks. The band is my really only big complaint it feels chintsy and cheap, the clasp spring fellout once but very simple to re-insert and if you have small wrist like me its definite resize. Other than that for the price its a cool mechanical watch.

    Product does looks amazing and the manufacturer put a lot of time on designing this affordable watch, i'm using it in a daily basis and still looks like the first day. Pros: Affordable, great looking, right size Cons: Lot of condensation, you can see it trough the glass
