Since 1993, the Seamaster Professional Diver 300M has enjoyed a legendary following. OMEGA’s 21st century models stay true to the original’s dive watch design, while introducing exciting new materials and movements.

On this 43.50 mm model, black ceramic [ZrO2] dominates. The case, bezel, wave-pattern dial, crown and helium escape valve, all in the same striking material, give the watch a very distinctive, uniform and sculptural look. To ensure visibility without affecting the overall aesthetic, OMEGA has introduced anthracite Super-LumiNova to the diving scale, the black PVD indexes and skeleton hands - and dot at 12H.

Completing the look is an integrated black rubber strap with black ceramic buckle. Adding some light to the darkness is a window with a clear view of the movement. Visible through the sapphire-crystal on the wave-edged caseback is OMEGA’s Co-Axial Master Chronometer Calibre 8806.
