OMEGA Seamaster Diver 300m Chronometer 42mm Blue Dial Watch

Keanes Code: 5233023


The Seamaster Professional Diver 300M, a legendary timepiece since 1993, now combines OMEGA's ocean heritage with modern innovation.

This 42mm stainless steel model boasts a blue ceramic bezel with a white enamel diving scale, a polished blue ceramic dial with laser-engraved waves, and a date window at 6 o'clock. Rhodium-plated skeleton hands and raised indexes are luminescent with white Super-LumiNova, and a conical helium escape valve enhances functionality.

It comes with a stainless steel bracelet and houses the OMEGA Master Chronometer Calibre 8800, visible through the sapphire-crystal caseback.
