Unworn, Omega Seamaster Planet Ocean 600M, Ref# 217.32.42.21.01.003, box and papers.

The OMEGA Seamaster Planet Ocean 600M Ref. 217.32.42.21.01.003 is a professional dive watch engineered for uncompromising performance in the harshest underwater environments while offering the refinement expected from one of Switzerland's finest watchmakers. Part of the latest Planet Ocean generation, this 42 mm model features a robust stainless steel case paired with an integrated black structured rubber strap for exceptional comfort and versatility. The polished orange ceramic unidirectional bezel is fitted with a white hybrid ceramic diving scale and a polished Grade 5 titanium inner ring, framing a matte black dial enhanced by four bold orange Arabic numerals. Rhodium-plated hands and applied indexes filled with white Super-LumiNova® provide outstanding legibility in low-light conditions, while a flat scratch-resistant sapphire crystal with anti-reflective treatment on both sides ensures exceptional clarity and durability. At its heart beats the OMEGA Co-Axial Master Chronometer Calibre 8912, a METAS-certified self-winding movement featuring a Co-Axial escapement, free-sprung balance with silicon balance spring, twin barrels mounted in series, and resistance to magnetic fields up to 15,000 gauss. The movement delivers a 60-hour power reserve and an independently adjustable hour hand for effortless time-zone changes. Completing its professional specifications are a screw-in crown, helium escape valve, and a Grade 5 titanium caseback engraved with the iconic Seamaster Seahorse medallion. Water-resistant to an impressive 600 meters.
