Citizen Promaster Aqualand Eco-Drive Depth Meter 53 mm Black Dial Strap [BN2029-01E]

The Citizen Promaster Aqualand BN2029-01E combines a substantial 53 mm stainless steel case with practical underwater measurement functions. Its black dial places depth information alongside the time, with luminous hands and markers supporting visibility in dim conditions. A black bezel and polyurethane strap reinforce its purposeful appearance, while the unidirectional elapsed-time scale provides a straightforward way to track time. The result is a distinctive dive watch whose proportions and controls reflect its specialised role.

Powered by natural or artificial light, Citizen’s Eco-Drive Calibre J250 offers approximately eleven months of operation on a full charge, with an indicator showing the remaining energy level. Water contact automatically activates depth measurement, and the analogue display reads to 70 metres. Maximum-depth memory retains the deepest point from the latest dive, while an audible alarm alerts the wearer to rapid ascent. These functions provide a supplementary reference alongside a primary dive instrument. A screw-down crown, screw-back case and thick anti-reflective mineral crystal complete a robust design for divers who appreciate useful instrumentation and the convenience of light-powered timekeeping.
