It was with OMEGA’s maritime legacy in mind that the brand launched its Planet Ocean line in 2005. Today, the stylish OMEGA Seamaster Planet Ocean 600M Master Chronometer pays homage to OMEGA’s dive watch heritage.

This model, with its scratch-resistant sapphire crystal, features a polished black ceramic dial with with Arabic numerals and a date window at the 3 o’clock position. Mounted on the 43.5 mm stainless steel case, is the world's premiere black ceramic bezel with orange rubber. The diving scale of the bezel is crafted with Liquidmetal™.

Other features include an alveol screw-in caseback and a stainless steel bracelet with patented extendable foldover clasp.

The OMEGA Seamaster Planet Ocean 600M Master Chronometer is water resistant to 600 metres / 2000 feet / 60 bar, and has a helium-escape valve. The OMEGA Master Chronometer calibre 8900 at the heart of this timepiece can be seen through the transparent caseback. To achieve Master Chronometer status, it has passed the 8 rigorous tests set by METAS (The Swiss Federal Institute of Metrology).

FEATURES

Anti-Magnetic: The movement is unaffected by exposure to strong magnetic fields, even those greater than 1.5 tesla (15,000 gauss).

Automatic Watch: A self-winding watch or automatic watch uses a mechanical movement whose main spring is wound automatically by the natural motion of the wearer's arm.

Chronometer: Label given to a watch which has undergone precision tests and received a certificate from an official body (COSC).

Date: The day of the month, displayed in a window on a watch dial at the 3 or 6 o’clock position, or within a subdial at 9 o'clock.

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 Certified: Guaranteeing the Swiss industry’s highest standard of precision, performance and magnetic-resistance, as set by the Swiss Federal Institute of Metrology (METAS).

Screw-In Crown: Self-locking crown, screwed into the tube of the case, used for highly water resistant divers' watches.

Transparent Case Back: A 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.
