Omega Seamaster Planet Ocean 600M Co-Axial 232.30.42.21.01.001 (42mm)

The Omega Seamaster Planet Ocean 600M Co-Axial (ref. 232.30.42.21.01.001) is a professional dive watch built for serious depth performance, combining a robust 42mm steel case with a black ceramic bezel and Omega's Co-Axial escapement.

The stainless steel case (15.80mm thick) houses a black dial with a date window at 3 o'clock, a helium-escape valve, a screw-in crown, and a transparent caseback, all protected by a domed scratch-resistant sapphire crystal with anti-reflective treatment on both sides. A black ceramic unidirectional rotating divers' bezel surrounds the dial. The self-winding OMEGA Co-Axial Calibre 8500 delivers a 60-hour power reserve and is chronometer-certified. Water resistant to 600 metres (60 bar), the watch is fitted on a stainless steel bracelet with a foldover clasp featuring a diver's extension.
