The OMEGA Seamaster Planet Ocean 600M Ref. 217.30.42.21.01.003 is a professional dive watch engineered for extreme underwater performance while maintaining the refined craftsmanship expected from OMEGA. As part of the latest Planet Ocean generation, this 42 mm model features a robust stainless steel case with polished and brushed finishes, paired with a matching stainless steel bracelet for exceptional durability and everyday comfort. The striking polished orange ceramic unidirectional bezel is fitted with a white hybrid ceramic diving scale and a Grade 5 titanium inner ring, framing a matte black dial accented by four vivid orange Arabic numerals. Rhodium-plated hands and applied indexes filled with white Super-LumiNova® provide outstanding visibility in all lighting conditions, while a flat scratch-resistant sapphire crystal with anti-reflective treatment on both sides ensures exceptional clarity. Powering the watch is the OMEGA Co-Axial Master Chronometer Calibre 8912, a METAS-certified self-winding movement featuring a Co-Axial escapement, 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, making it ideal for frequent travelers. A screw-in crown, helium escape valve, and Grade 5 titanium caseback engraved with the iconic Seamaster Seahorse medallion reinforce the watch's professional diving credentials. Water-resistant to an impressive 600 meters.
