This 42 mm Seamaster Diver 300M has a case and bracelet in stainless steel. The ceramic dial, in OMEGA’s own Summer Blue, is PVD-treated and has a gradient finish to reflect the watch’s level of water resistance. It also includes the 300M’s famous wave pattern.
A blue ceramic bezel with a Summer Blue enamel (Grand feu) diving scale encircles the dial, which has rhodium-plated skeleton hands and raised indexes, filled with a unique light blue Super-LumiNova.
Turning the watch over reveals a stamped commemorative Seamaster logo depicting a trident-bearing Poseidon and two seahorses: OMEGA’s 1956 original and the brand’s current design. Behind which sits OMEGA’s Co-Axial Master Chronometer calibre 8800, certified at the industry’s highest level by the Swiss Federal Institute of Metrology (METAS).
