OMEGA Seamaster Diver 300M Co-Axial Master Chronometer 42MM

‹Return to Previous Page


Since 1993, the Seamaster Professional Diver 300M has enjoyed a legendary following. Today’s modern collection has embraced that famous ocean heritage and updated it with OMEGA’s best innovation and design.

This 42 mm model is crafted from stainless steel and includes a black ceramic bezel with a white enamel diving scale. The dial is polished white ceramic and features laser-engraved waves and Seamaster highlighted in red.

The polished, blackened skeleton hour and minute hands are filled with white Super-LumiNova. The second’s hand features a varnished red tip.

The watch is presented on a polished-brushed stainless steel bracelet and is driven by the OMEGA Master Chronometer Calibre 8800, which can be seen through the sapphire-crystal on the wave-edged case back.

The Seamaster 300 Master Co-Axial recalls its iconic namesake launched in 1957 but it has been completely updated and upgraded to include the brand’s most innovative technology and materials including Liquidmetal™, 18K Ceragold™, 18K Sedna™ gold, an extendable bracelet and, of course, the fully anti-magnetic Master Co-Axial mechanical movement.

In 1957, the OMEGA Seamaster Diver 300 – a watch designed specifically for divers and professionals who worked underwater. More than half a century later, the Seamaster 300 is reintroduced in a completely upgraded and enhanced form, prepared to equip a new generation of adventurers on land and in the oceans.

The 41 mm Seamaster 300 case metal options include stainless steel, grade 5 titanium, 18K yellow gold, and 18K Sedna™ gold. Bi-color models pair grade 5 titanium or stainless steel with either 18K Sedna™ gold or 18K yellow gold. The bezels of the full titanium and stainless steel models have Liquidmetal™ diving scales while the gold or bi-color watches have OMEGA Ceragold™ diving scales. The Seamaster 300 is water-resistant to 30 bar (300 meters / 1000 feet).
