Omega Seamaster Planet Ocean 600M 39.5mm White Dial Stainless Steel and Sedna™ 18k Rose Gold Strap 215.23.40.20.04.001

DESCRIPTION
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 white ceramic dial with Arabic numerals and a date window at the 3 o’clock position. The white ceramic unidirectional bezel with OMEGA Ceragold™ diving scale is mounted on a 39.5 mm stainless steel and 18K Sedna™ gold case.
Other features include an alveol screw-in caseback and a white leather strap with rubber lining.
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 8800 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).
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 caseback: A transparent caseback – 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.
