HydroConquest 43mm Blue Rubber Strap

Blue runs through the Longines HydroConquest L37824969: a sunray blue dial, a unidirectional rotating ceramic bezel and a rubber strap, all on a 43 mm stainless steel case. The dial has applied Arabic numerals and indexes, silvered polished hands, a date display and Super-LumiNova on the hands and markers for legibility in the dark.

Inside is the L888 self-winding mechanical movement, beating at 25,200 vibrations per hour with a power reserve of approximately 72 hours. A sapphire crystal and screw-down stainless steel case back support 300 meters of water resistance, which makes this a proper dive-capable watch. The 21 mm rubber strap, about 8 inches long, uses a double safety folding clasp with push-piece opening, and the case is 11.90 mm thick.
