/ Planet Ocean 600M Co-Axial Chronometer Chronograph 45.5 mm Black Dial
With this OMEGA Seamaster Planet Ocean 600M Chronograph Ceragold, OMEGA has paired its rich maritime legacy with its tradition of unparalleled quality and innovation – two brand-defining characteristics. This chronograph model features a black dial with a date window at the 3 o’clock position and a scratch-resistant sapphire crystal.
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. Most remarkable is the black ceramic bezel with its impressive 18K red gold diving scale, created using the world premiere Ceragold™ technology. The OMEGA Seamaster Planet Ocean 600M Chronograph is water resistant to 60 bar (600 metres / 2000 feet), and has a helium-escape valve.
The 45.5 mm 18K red gold case is presented on a black leather strap. Powering this timepiece is the OMEGA Co-Axial calibre 9301, visible through the transparent caseback.
The chronograph function is a mechanism for measuring time intervals. A can therefore be used to time events while displaying the time like any traditional watch.

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