About This Piece

Catching a case of the blues has never felt, or looked, so good than with this OMEGA Seamaster Diver 300m Chronometer Stainless Steel and Ceramic Automatic Watch. PVD treated with a gradient finish, the ceramic dial reflects its impressive 300m water resistance in both substance and style. Just look at that iconic wave pattern and the blue ceramic bezel with an enamel diving scale (in OMEGA’s Summer Blue)... And as for the unique light blue Super-LumiNova on the rhodium-plated skeleton hands and raised indexes? Well, you’ll never lose track of time, even in the darkest depths.

Editor's Notes


A legend of oceanic proportions, the OMEGA Seamaster 300 of today is leaps and bounds from the original. Although it may have been born in 1957, the Seamaster 300 has seen a number of enhancements over the years. And today? This clean, crisp and Master certified collection still maintains its vintage charm.

Turn this beauty around and you’ll find a stamped Seamaster logo that pays homage to OMEGA's rich history. Poseidon, the mighty trident-bearing god, stands tall beside two seahorses - a symbol of the legendary 1956 original. Powered by the Co-Axial Master Chronometer calibre 8800 and with a 55 hour power reserve, you can trust this watch to keep up with you, above or below the surface.
