Omega Seamaster Diver 300m Co-Axial Chronometer

The polished Sedna™ gold indexes and facetted hands, filled with white Super-LumiNova, contrast beautifully with the black dial. Completing the look is an integrated black rubber strap with black ceramic buckle.

The polished-brushed oriented caseback with wave-edged design features OMEGA’s patented NAIAD LOCK. Powering the watch is OMEGA’s Co-Axial Master Chronometer Calibre 8806.
