Since 1993, the Seamaster Professional Diver 300M has celebrated its oceanic heritage with OMEGA's innovation.

This 42mm model blends stainless steel and 18K Sedna™ gold, boasting a black ceramic bezel featuring a Ceragold™ diving scale. Its black ceramic dial showcases laser-engraved waves and a date window at 6 o'clock. The skeleton hands and raised indexes in 18K Sedna™ gold are luminescent, and the helium escape valve sports a conical design.

This watch comes on a black rubber strap, powered by the OMEGA Master Chronometer Calibre 8800, visible through the sapphire-crystal caseback with a wave-edged design.
