Omega Seamaster Planet Ocean 600M Mens 45.5mm Automatic Co-Axial Divers Mens Watch O21530465103001

It was with OMEGA’s maritime legacy in mind that the brand launched its Planet Ocean line in 2005. The stylish OMEGA Seamaster Planet Ocean 600M Master Chronometer Chronograph 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 6 o’clock position. The dial presents a small seconds sub-dial, as well as 60-minute and 12-hour counters on one dial for intuitive reading of elapsed time. The blue ceramic unidirectional rotating divers’ bezel, with its Liquidmetal™ diving scale, is mounted on a 45.5 mm stainless steel case.

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 Chronograph is water resistant to 60 bar (600 metres / 2000 feet), and has a helium-escape valve. The OMEGA Master Chronometer calibre 9900 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 9900: Self-winding chronograph with column wheel and Co-Axial escapement. Certified Master Chronometer, approved by METAS, resistant to magnetic fields reaching 15,000 gauss. Silicon balance-spring, 2 barrels mounted in series, time zone function. Central hour, minute and chronograph seconds hands, small seconds hand, 12-hour and 60-minute recorders. Rhodium plated finish with Geneva waves in arabesque.

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.

Chronograph: The chronograph function is a mechanism for measuring time intervals. A chronograph watch can therefore be used to time events while displaying the time like any traditional watch.

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.

Small Seconds: A hand on a sub-dial which tracks seconds typically it completes a full rotation in one minute.

Transparent Case Back: A transparent case back - frequently made of sapphire - makes it possible to see the movement inside the watch.

Unidrectional 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.
