Omega Seamaster Diver 300M Co-Axial Master Chronometer SS Black Dial

The Omega Seamaster Diver 300M Co-Axial Master Chronometer in reference 210.30.42.20.01.001 is a modern dive icon built for serious daily wear, blending legibility, comfort, and METAS-level performance. Housed in a 42mm stainless steel case, it features a distinctive black wave dial and a black ceramic bezel designed to match the unmistakable Seamaster character. Powering the watch is the Omega Co-Axial Master Chronometer automatic caliber 8800, engineered for strong accuracy and enhanced resistance to magnetic fields. A functional date display at 6 oclock rounds out the layout for life both above and below the surface. Collector-wise, this reference is especially attractive because it represents the Seamaster 300M era that uses the wave-dial aesthetic alongside the Co-Axial Master Chronometer caliber family. The watch is engineered for professional-grade diving capability with a 300m water resistance rating, while still maintaining a balanced wrist presence at its 50mm lug-to-lug profile. With its integrated dive DNA and contemporary finishing, it is a go-to pick for enthusiasts who want a tool watch that also looks at home in formal settings. Excellent Condition with Omega box and undated papers.
