    Purple watch
    Color: F-Purple
    The watch is cute but the magnet clasp is not sturdy so the watch continues to loosen up continously. So,I'm satisfied

    Beautiful Watches
    Color: F-Rose Gold
    I ordered three of these watches! They were delivered promptly. The seller was very responsive with my question regarding delivery as I wanted to receive them before my birthday of August 29th. As soon as I saw them I knew I made the right choice I ordered the black coffee brown and rose gold all three of them are beautiful they are by far the nicest watches I've ever owned I would say even nicer than my Movado. If you are thinking for a watch for yourself whether business or casual or a gift for someone for Christmas order one of these with the Platinum strap. You won't be disappointed!
