Planet Ocean 600M Omega Co‑axial Master Chronometer GMT 45.5 mm Deep Black
Black ceramic on rubber strap
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 red represents the first colour that is no longer visible at a depth of approximately 5 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. Red 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 red Arabic numerals, and 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 red 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).
24 hours GMTA GMT function means that the watch has a second hour hand which completes one full rotation in 24 hours and a 24-hour index on the dial. Particularly useful for wearers who wish to track two time zones.
The movement is unaffected by exposure to strong magnetic fields, even those greater than 1.5 tesla (15,000 gauss).
Label given to a watch which has undergone precision tests and received a certificate from an official body (COSC).
The day of the month, displayed in a window on a watch dial typically at the 3 o'clock or 6 o'clock position.
Helium escape valve
Decompression system which allows helium to escape from inside the watch when the watch is worn for professional use in pressure chambers. (Long-term underwater work, crude oil exploration, etc.)
Master Chronometer CertifiedGuaranteeing the Swiss industry’s highest standard of precision, performance and magnetic-resistance, as set by the Swiss Federal Institute of Metrology (METAS).
Self-locking crown, screwed into the tube of the case, used for highly water resistant divers' watches.
Transparent case backA transparent case back - frequently made of sapphire - makes it possible to see the movement inside the watch.
Unidirectional rotating bezel
A bezel which turns in only one direction. Particularly useful for divers who cannot accidentally rotate it in the wrong direction, which could cause them to miscalculate their dive times. A rotating bezel makes it easy to measure elapsed time.
