Omega Seamaster Diver 300m
The Seamaster was first introduced by Omega in 1957, as a professional diver’s watch. It was the first Omega to feature a rotating bezel, allowing the wearer to measure dive times.
Fast-forward nearly seventy years and the Seamaster is still a firm favourite with watch enthusiasts. This reference 210.30.42.20.04.001 version features a bold polished white ceramic dial, decorated with those iconic waves. Skeletonised hands are tipped with Super-LumiNova, as well as the indices and the diving scale on the ceramic bezel, which allow for exceptional legibility.
The 42mm steel case has a presence on the wrist whilst still being comfortable to wear. It is predominantly brushed with polished finishes to highlight its sleek edges.
Through an exhibition case back you can appreciate Omega’s Calibre 8500 automatic movement. Known to be robust and reliable, it is both a Certified Master Chronometer and approved by METAS. It also features a free sprung balance with silicon balance spring, a co-axial escapement and comfortably offers a power reserve of 55 hours.
The watch is fitted with a sporty steel bracelet featuring a diver’s extension clasp. It would also suit any number of straps such as leather for a dressier look or even a NATO or rubber for a more relaxed feel.
We are excited to present this watch in excellent, like-new condition. It comes supplied as a full set including an Omega warranty to December 2025 and an additional 6-month warranty from Watch Concierge Services.
