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 polished-brushed bracelet in stainless steel, featuring an extendable foldover rack-and-pusher with an extra diver extension. 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.
