DESCRIPTION
It was with OMEGA’s maritime legacy in mind that the brand launched its Planet Ocean line in 2005. Today, the stylish models continue to pay homage to OMEGA’s dive watch heritage.This 45.50 mm stainless steel model features a ceramised titanium dial with a small seconds counter and a date window, as well as 60-minute and 12-hour counters at the 3 o'clock position. Orange ceramic is used on the rings of the pushers and also for the unidirectional bezel with its diving scale filled with liquid ceramic and Super-LumiNova.Other features include an alveol screw-in caseback and an integrated stainless steel bracelet with patented extendable foldover clasp and diver extension.The watch is water resistant to 600 metres / 2000 feet / 60 bar 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).

Features
Anti-magnetic: The movement is unaffected by exposure to strong magnetic fields, even those greater than 1.5 tesla (15,000 gauss).
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.
Time zone function: Allows the hour hand to be easily adjusted to different time zones without stopping the watch.
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.
