Omega Seamaster Diver 300M Co-Axial Master Chronometer 42mm — 210.32.42.20.01.003

Built for the depths and styled for everyday wear, the Omega Seamaster Diver 300M 210.32.42.20.01.003 pairs the collection’s signature dive-watch DNA with modern precision engineering. This 42mm stainless steel timepiece is fitted with a black anodized aluminium unidirectional bezel and a wave-engraved black aluminium dial, echoing the ocean heritage the Seamaster line has carried since 1993.

Powered by the Omega Co-Axial Master Chronometer Calibre 8806, this watch is independently certified by METAS to the Master Chronometer standard, meaning it delivers exceptional accuracy and resists magnetic fields up to 15,000 gauss. The rhodium-plated, skeletonized hands and indexes are filled with white Super-LumiNova for strong low-light legibility underwater or on land, while the sapphire caseback offers a clear view of the automatic movement’s finely finished rotor and bridges.

Rated to 300 metres water resistance and fitted with a screw-down crown and scratch-resistant sapphire crystal, this Seamaster Diver 300M is as capable in the water as it is at the office. It’s presented on an integrated black rubber strap with a foldover clasp for a secure, streamlined fit on the wrist.

Whether you’re adding to a growing watch collection or looking for a genuinely daily-wearable dive watch from one of Switzerland’s most recognised names, the Omega Seamaster Diver 300M 210.32.42.20.01.003 delivers Swiss Made craftsmanship, dive-ready performance, and understated style in equal measure.
