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.
