OMEGA Seamaster Master Diver 300m Chronometer 42mm Black Dial Watch

Keanes Code: 5233022


Since 1993, the Seamaster Professional Diver 300M has celebrated its oceanic heritage. This 42mm stainless steel model features a black ceramic bezel with a white enamel diving scale, a polished black ceramic dial with laser-engraved waves, and a 6 o'clock date window.

Rhodium-plated skeleton hands and raised indexes glow with white Super-LumiNova, and the conical helium escape valve enhances functionality.

It's worn on a stainless steel bracelet and powered by the OMEGA Master Chronometer Calibre 8800, visible through the sapphire-crystal caseback.
