Omega Seamaster Diver 300 M

Omega developed Bronze Gold specifically to solve the problem with bronze watches: ordinary bronze alloys contain enough copper to mark the skin and oxidise unpredictably. Adding gold, palladium and silver produces a metal that develops a slow, even patina without the drawbacks. Around it sits the Seamaster's ceramic bezel with enamel diving scale and a conical helium escape valve, with a Co-Axial Master Chronometer calibre inside.
