Engineered to command the sea, the Citizen Promaster Dive Polyurethane Strap Men's Watch BN0230-04E is a style icon from the Promaster Marine collection. Inspired by the majestic Orca whale, this sporty, functional dive watch features a silver-tone stainless steel case, black three-hand dial, and date display with white hour indices and bezel indentations for a unique look. Anti-magnetic and anti-shock resistant, it contains a one-way rotating elapsed-time bezel and luminous hands and markers for legibility in any environment. The black polyurethane strap resembles the orca's fin and secures with a buckle, and the watch is designed to be water resistant up to 200m with a screw-down crown. Boasting Eco-Drive technology that doesn't require a battery, it comes in a scuba tank-inspired box for diving enthusiasts and collectors.
