Omega Seamaster Diver 300M
Ref. 210.30.42.20.06.001

The Omega Seamaster Diver 300M ref. 210.30.42.20.06.001 is a modern classic in Omega’s dive-watch lineup, pairing professional-grade performance with a clean and versatile grey dial execution.

This example comes as a full set and features a 42mm stainless steel case on the matching stainless steel bracelet. The grey ceramic dial has Omega’s signature laser-engraved wave pattern, applied hour markers, skeletonized hands, and a date window at 6 o’clock. The matching ceramic bezel gives the watch a refined, monochromatic look that works just as well casually as it does in a more dressed-up setting.

Powering the watch is Omega’s Co-Axial Master Chronometer Caliber 8800 automatic movement, visible through the sapphire exhibition caseback. The movement is METAS-certified, highly resistant to magnetism, and built for reliable everyday wear. As part of the Seamaster Diver 300M family, the watch also offers 300 meters of water resistance, a helium escape valve, screw-down crown, sapphire crystal, and a professional dive-watch build.

The grey dial on bracelet is one of the most versatile Seamaster configurations, offering a sharp, modern look while still carrying all the heritage and capability that make the Diver 300M one of Omega’s most recognizable models.
