Really nice watch!
Color: 3675 ALL Black
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.

Good attractive value
Color: 3676 ALL Black
This watch is a very good value imo. Looks like a quality watch. Band is adjustable and comes with a tool to assist in removing band pins. Keeping time very good. I would buy it again and will buy another in a different style

Men’s Watch
Color: 3675 Silver Black
Within two weeks of normal wear, the watch quit keeping time and the band broke. Returned for a refund.
