Promaster Dive Eco-Drive 41mm

The Citizen Promaster Dive Eco-Drive combines ISO-certified dive readiness with sleek, everyday wearability. Whether you choose the bold blue dial (BN0260-54L) or the clean, classic black dial (BN0261-51E), this 41mm stainless steel diver is a reliable tool watch powered by light — never needing a battery change.

Built to handle serious underwater use, the Promaster features a 200-meter water resistance rating, screw-down crown, and a unidirectional dive bezel for timing elapsed minutes. The case measures 41mm wide, 48mm long, and 11.6mm thick, striking an excellent balance between capability and comfort. Oversized hands and markers are filled with luminous material for visibility in low light, and a sapphire crystal offers scratch resistance well above the standard. The watches also come on a stainless steel bracelet that features an on the fly micro-adust system.

Inside, Citizen’s E168 Eco-Drive movement converts any light source into energy, giving the watch a 6-month power reserve on a full charge. The solid-link stainless steel bracelet is secured with a safety fold-over clasp and push-button release. With dive function at its core and streamlined style up top, the Promaster Dive is built to go wherever your next adventure leads.
