Planet Ocean 600M Seamaster Steel Master Chronometer 217.32.42.21.01.001

The Seamaster Planet Ocean pays homage to OMEGA’s dive watch heritage and perfectly encapsulates the brand’s commitment to exploration, innovation, and style. This 42 mm model is crafted with a case in polished-brushed stainless steel. It features a polished black ceramic bezel ring with a diving scale in white enamel, while the inner ring is made from polished grade 5 titanium. The black dial is presented with a matte finish, and includes rhodium-plated hands and indexes with white Super-LumiNova. Along with transferred wording in white, there are also four rhodium-plated Arabic numerals. Powered by the Co-Axial Master Chronometer Calibre 8912, this Seamaster Planet Ocean is worn on a black rubber strap with a stainless steel link to the case and a foldover clasp. On the reverse side of the watch, the screw-in caseback is made from polished-brushed grade 5 titanium, and displays OMEGA’s famous seahorse emblem.
