Since 1993, the Seamaster Professional Diver 300M has a storied history. The 42 mm stainless steel model now combines this legacy with OMEGA's latest innovations.

It boasts a black ceramic bezel with a white enamel diving scale, a polished white ceramic dial with laser-engraved waves and red Seamaster lettering. The hands are blackened and filled with white Super-LumiNova, while the seconds hand has a red tip.

The watch is worn on a black rubber strap and houses the OMEGA Master Chronometer Calibre 8800, visible through the sapphire-crystal caseback with a wave-edged design. A modern take on a timeless classic.
