Introducing the CITIZEN PROMASTER BN1024-01Z Eco-Drive Professional Diver 300m, a cutting-edge timepiece designed for serious underwater exploration. As part of CITIZEN’s legendary PROMASTER series—trusted by professionals for over 35 years—this men's dive watch combines rugged durability with advanced technology.

Powered by CITIZEN’s in-house Eco-Drive Caliber E365, it runs for an impressive 365 days on a full charge, even in low-light conditions. Built for saturation diving, this professional-grade diver’s watch boasts 30 bar (300m) water resistance and features a helium escape valve for deep-sea expeditions. Inspired by the popular BN0156-05E, it carries forward iconic design elements such as the 4 o’clock crown and crown guard, bold indices, distinctive hour and minute hands, and a rotating bezel.

The glossy red dial mimics the deep-sea gradient, darkening subtly at the 6 o’clock mark, while the black BENEBiOL™ polyurethane strap—a plant-based, hydrolysis-resistant material—offers durability with reduced environmental impact. The robust 46mm stainless steel case is topped with anti-reflective sapphire glass for superior clarity and protection. Weighing 161g, this watch blends strength with comfort.

The case back features an engraved diver’s helmet, symbolizing its professional heritage. Whether you're a recreational diver or a seasoned explorer, the BN1024-01Z is a standout in the world of professional dive watches.

What we love: The complete dive watch with a 365 day power reserve!
