Citizen Promaster Dive BN0230-04E Eco-Drive Orca Black Dial Men's Dive Watch

Citizen BN0230-04E Promaster Dive "Orca" is a distinctive professional dive watch inspired by the powerful shape of the orca whale. Originally introduced overseas and later released in Japan due to popular demand, this award-winning design features a robust 46mm stainless steel case paired with a durable black polyurethane strap. The bold black dial is complemented by oversized luminous hands and markers for outstanding underwater readability, while the uniquely sculpted unidirectional dive bezel echoes the flowing lines of an orca. Protected by a convex mineral crystal, this ISO-compliant diver is built for both serious underwater use and everyday adventure.

Powered by Citizen's dependable Eco-Drive Caliber E168, the BN0230-04E is fueled by any natural or artificial light source, eliminating the need for battery replacements. It provides approximately 6 months of operation on a full charge and includes practical features such as a date display, quick-start function, low-charge warning, overcharge prevention, and impact detection. A screw-down crown, 200-meter ISO-certified water resistance, and unidirectional rotating bezel make this watch a reliable companion for diving, snorkeling, and outdoor activities.
