Unworn, Omega Seamaster Planet Ocean 600M, Ref# 217.32.42.21.01.004, box and papers.

The OMEGA Seamaster Planet Ocean 600M Ref. 217.32.42.21.01.004 is a professional dive watch engineered to meet the highest standards of performance while showcasing OMEGA's latest innovations in Swiss watchmaking. Part of the newest Planet Ocean generation, this 42 mm model combines a robust stainless steel case with a vibrant orange integrated rubber strap, creating a bold contemporary aesthetic inspired by the collection's diving heritage. The polished orange ceramic unidirectional bezel, featuring a white hybrid ceramic diving scale and a Grade 5 titanium bezel ring, frames a matte black dial highlighted by four matching orange Arabic numerals. Rhodium-plated hands and applied indexes filled with white Super-LumiNova® provide exceptional legibility in all lighting conditions, while a flat scratch-resistant sapphire crystal with anti-reflective treatment on both sides ensures optimum clarity. Powering the watch is the OMEGA Co-Axial Master Chronometer Calibre 8912, a METAS-certified automatic movement equipped with a Co-Axial escapement, silicon balance spring, twin barrels mounted in series, and resistance to magnetic fields up to 15,000 gauss. The calibre delivers a 60-hour power reserve and features an independently adjustable hour hand, making it ideal for frequent travelers. Completing the professional specification are a screw-in crown, helium escape valve, and a Grade 5 titanium caseback engraved with the iconic Seamaster Seahorse medallion. Water-resistant to 600 meters.
