This is a remarkable BALL Wristwatch, Model Engineer Hydrocarbon with reference number DM3000ASCJSL. Bracelet is expandable to use with wetsuit. Uses tritium in crown and numbers for excellent night vision while diving.
The watch is very stylish. It's heavy duty, not for a thin wrist or a person who is uncomfortable with heavy jewelry. Love the face. It illuminates during the day with a light shade, depending where the light is coming from. It has a serious glow at night, so reading time is no issue at anytime day or night.
