Omega Seamaster Planet Ocean 600M Co-Axial Worldtimer 45.5 Master Chronometer GMT Ceramic / Black - Grey / Rubber Ref. 215.92.46.22.01.007

The Omega Seamaster Planet Ocean 600M Worldtimer 215.92.46.22.01.007 debuted in 2025 as part of the Planet Ocean collection, integrating a world-time display within a deep-sea capable ceramic sports watch. The case measures 45.5 mm in diameter and is executed entirely in black ceramic, with a brushed case and matching brushed ceramic bezel. The unidirectional bezel incorporates a laser-ablated diving scale that is polished in positive relief. A domed sapphire crystal with anti-reflective treatment on both sides protects the dial, while water resistance is rated to 600 metres. Lug-to-lug length measures 51.5 mm, with a total thickness of 17.38 mm. At the centre of the dial is a topographic depiction of the Earth, viewed from above the North Pole. This map is produced on a grade 5 titanium surface using laser ablation and grey varnish. Surrounding the central map is a 24-hour indicator, divided into night and day sections and executed on transparent hesalite. The outer dial section is finished in DLC black and features a laser-ablated and polished honeycomb pattern. Diamond-brushed indexes are filled with grey Super-LumiNova, while the grey PVD-coated hands are also treated with grey Super-LumiNova. An outer ring in grey varnish frames the dial, alongside a global destination ring that includes OMEGA’s home city of Bienne. The watch is fitted with an integrated black structured rubber strap with a black-grey underside and grey stitching. It is secured by a foldover clasp in ceramic and ceramised titanium. Powering the watch is the self-winding Co-Axial Master Chronometer calibre 8938. The movement offers a power reserve of approximately 60 hours and meets METAS certification standards for precision, magnetic resistance, water resistance, and overall performance. It is visible through the sapphire crystal caseback.
