This Citizen marine sport watch is powered by a Citizen Caliber 8200 automatic movement that also hand winds. It features a 46.2mm diameter stainless steel case, a heavy-duty polyurethane strap, luminous hands and hour markers, 60-minute marked blue 120-click uni-directional bezel, and a day and date window at the 3:00 position on the dial. It is water resistant to 100 meters (Ok for swimming, snorkeling, but not scuba diving).
