Omega Seamaster Planet Ocean 600M 45.5 mm, black ceramic on rubber strap

In this remarkable 45.5 mm divers’ chronograph, the casebody has been crafted from a single block of ceramic, while orange rubber has been blended with ceramic to create a unique unidirectional bezel. This blend covers the first 15 minutes, with Liquidmetal completing the rest of the diving scale. Orange rubber has also been used on the brushed pushers.

The black ceramic dial includes 18K white gold hands and indexes. OMEGA has also created an oriented caseback through its patented NAIAD LOCK system so that the engraved wording sits pleasingly in position.

The watch sits on a black rubber strap with orange stitching and an anti-bacterial treatment. It is driven by the OMEGA Master Chronometer Calibre 9900. To achieve Master Chronometer status, it has passed the 8 rigorous tests set by METAS (The Swiss Federal Institute of Metrology).
