Citizen Promaster BN1024-01E Eco-Drive Diver's 300M Watch

Diver's 300M Watch for Deep-Sea Exploration

The Citizen Promaster BN1024-01E is an Eco-Drive diver's watch built for 300-meter water resistance. It suits professional divers and adventurers who need reliable timekeeping during deep-sea exploration and water sports. Solar-powered Eco-Drive technology charges from any light source, removing the requirement for periodic battery changes.

300-Metre Water Resistance

The 300M rating provides ample headroom for saturation diving and prolonged immersion well beyond recreational limits. Eco-Drive delivers continuous operation under normal light exposure, so the movement runs without intervention. The power reserve depletes only after extended storage in total darkness, at which point recharging restores function.

46mm Stainless Steel Case

A 46.00 mm stainless steel case houses the movement behind a scratch-resistant sapphire crystal and a screw-down crown that seals the 300M depth rating. The polyurethane rubber strap secures with a buckle clasp, fitting a range of wrist sizes and over thin wetsuit sleeves. A unidirectional rotating bezel with index and dotted markers tracks elapsed dive time, while a date display at three o'clock adds daily utility.
