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

Within two weeks of normal wear, the watch quit keeping time and the band broke. Returned for a refund.
