Seamaster Planet Ocean 600M Co-Axial Master Chronometer GMT 45.5MM Watch

This remarkable 45.5 mm timepiece is the combination of a GMT model and a diving watch. It is coloured totally black to represent the ocean at a depth of 300 m. The glossy and brushed casebody has been crafted from a single block of ceramic, the same material used for the unidirectional bezel and the dial with Arabic numerals.

A new GMT ring has also been fixed on the dial while the diving scale and OMEGA logo on the crown have been decorated with Liquidmetal™. The hands are 18K white gold and are coated in white Super-LumiNova. In another first, OMEGA has created an oriented screw-in caseback so that the engraved wording sits pleasingly in position. This has been achieved through OMEGA’s new and patented ceramic Naiad Lock.
