The pushers are also polished black ceramic, as well as the dial, which features laser-engraved waves in a positive relief and a date window at 6 o’clock.The subdial rings and hands are in 18K Sedna gold, while the central hands and indexes are 18K Sedna gold and filled with white Super-LumiNova.The watch is presented on a rubber strap and is driven by the OMEGA Master Chronometer Calibre 9901, which can be seen through the sapphire-crystal on the wave-edged caseback.
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.
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.
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.
