MPN: O21563442103001

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 blue ceramic dial with Arabic numerals and a date window at the 3 o’clock position. The blue ceramic unidirectional bezel with OMEGA Ceragold™ diving scale is mounted on a 43.5 mm 18K Sedna™ gold case.

Other features include an alveol screw-in caseback and a blue leather strap with rubber lining and an 18K Sedna™ gold 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 8901 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).

Calibre Omega 8901: Self-winding movement and co-axial escapement. Certified by METAS as a Master Chronometer, insensitive to magnetic fields of up to 15,000 Gauss. Free balance spring with spiral spring made of silicon, two barrels installed one behind the other, automatic double-sided winding. Time zone function. 18K Sedna ™ gold rotor and balance bridge and luxurious finish with Geneva stripe arabesques.

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.

Sedna Gold™: Sedna Gold™ is an 18K rose gold alloy, fusing pure gold with copper and palladium, in order to guarantee that your gold watch has long lasting lustre.

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.
