CITIZEN PROMASTER Professional Diver 300 m For over 35 years, CITIZEN’s PROMASTER series has delivered professional-grade performance. The latest model, BN1024-01E, is an Eco-Drive Professional Diver 300 m. Powered by the light-driven caliber E365, it boasts a 365-day power reserve. This saturation diver’s watch features a helium release valve and is water-resistant to 30 bar (300 m). Its design draws inspiration from the popular PROMASTER BN0156-05E, sharing the 4 o’clock crown, crown guard, bold hands, indices, and rotating bezel. The glossy dial echoes deep-sea tones, darkening near 6 o’clock. The strap is made from BENEBiOL™, a plant-based polyurethane that resists hydrolysis and reduces environmental impact. A diver’s helmet, symbolizing the diving legacy, is engraved on the case back.
