Not much sunlight reaches 300 meters below the surface of the water. This Black Black version of Omega's Seamaster 300M diver would be right at home there. Nearly every visible part — including the 43.5mm case, bezel, wave-pattern dial, and crown — is made from black ceramic. To help with visibility, the diving scale, black PVD indexes and skeleton hands, and 12H dot have been coated with anthracite Super-LumiNova. The all-black look is completed by a black rubber strap with black ceramic buckle, leaving the automatic Master Chronometer Calibre 8806 movement, visible through the sapphire crystal caseback, as the only light component in sight. Arriving in stores this July.
