Really nice and clean looking watch. Fairly easy to adjust the watch band, with a little patience. Item description stated battery operated, but I don’t think it is as there is no indication that it has a battery in it. Other than that, really decent watch! I would have given it a five star rating if it were battery powered.

Great price

Color: 3675 Silver Grey

The watch looks like it should cost more than the actual price. It catches people's eye and so far it keeps accurate time. Keep in mind I've only had the watch about two weeks. Of my 10 every day watches this one is the most attractive.
