Exploring the dark side of the ocean, OMEGA has evolved its ceramic expertise to produce the Seamaster Planet Ocean “Deep Black”. This remarkable 45.5 mm timepiece is the combination of a GMT model and a diving watch. The addition of blue represents the last colour you'll see in the ocean at a depth of approximately 275 m.
The matt casebody has been crafted from a single block of ceramic, and for the first time, rubber has been blended with ceramic to create a unique unidirectional bezel. This colourful innovation can be seen covering the first 15 minutes, while Liquidmetal™ completes the rest of the diving scale. Blue rubber injections have also been used to colour the OMEGA logo on the crown and helium escape valve symbol.
On the black ceramic dial, a GMT ring has been added, as well as blue Arabic numerals, and brushed hands and indexes that are crafted from 18K white gold with a white Super-LumiNova coating. In another first, OMEGA has created an oriented caseback so that the engraved wording sits pleasingly in position. This has been achieved through OMEGA’s new and patented ceramic Naiad Lock.
Other features include an alveol pattern on the screw-in caseback and a black rubber strap with blue stitching and an anti-bacterial treatment. The Planet Ocean “Deep Black” is water-resistant to 60 bar and is driven by the OMEGA Master Chronometer calibre 8906. To achieve Master Chronometer status, it has passed the 8 rigorous tests set by METAS (The Swiss Federal Institute of Metrology).
