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.

With a history that dates back to the founding of the Shokosha Watch Research Institute in 1918, Citizen Watch Co. was formally established in 1930 with the goal of creating high-quality yet accessible timepieces for the Japanese market. Headquartered in Nishitokyo, Tokyo, Japan, Citizen is one of the world's largest and most vertically-integrated watch manufacturers. In addition to producing timepieces under its own name, Citizen also serves as the parent company for a number of other brands including Bulova, Alpina, Arnold & Son, Frederique Constant, Campanola, and Miyota. Citizen’s list of horological accomplishments is both long and impressive, including everything from creating Japan’s first fully-waterproof wristwatch to currently holding the title for the world’s most accurate movement, which is capable of astonishing precision within just one second per year.
