CITIZEN PROMASTER Professional Diver 300m The CITIZEN PROMASTER series has stood for professional-grade functionality for over 35 years. The new BN1024-01Z model is an Eco-Drive Professional Diver 300m, powered by the in-house E365 caliber with a 365-day power reserve when fully charged. It incorporates key design elements from popular PROMASTER Diver models and is built as a saturation diver’s watch, featuring a helium release valve and 300m (30 bar) water resistance. Inspired by the well-known BN0156-05E, it retains the 4 o’clock crown, crown guard, distinctive indices, bold hour and minute hands, and a robust rotating bezel. Its glossy dial reflects the dark tones of the deep sea, deepening toward 6 o’clock. The strap is made from BENEBiOL™, a plant-based polyurethane that resists moisture degradation and is eco-friendly. A diver’s helmet emblem is engraved on the case back, honoring the watch’s deep-sea legacy.
