• Additional Information: The Aquadive Time-Depth Model 50 is a rare 1970s dive watch known for its innovative, built-in electronic depth gauge. It combined a mechanical depth gauge with a battery-powered electronic movement and a unidirectional rotating bezel for timing dives. At a time when divers needed separate instruments, the Model 50 was groundbreaking for having both functions in one large, tool-focused package. The ESA Y29154 movement in Aquadive Time-Depth 50 is a modified electronic movement that uses a battery to power a balance wheel and a unique hydraulic system to measure depth via an orange hand.
