Description
Feature Anti-magnetic: The movement is unaffected by exposure to strong magnetic fields, even those greater than 1.5 tesla (15,000 gauss). Chronograph: Complicated watch with a function for measuring short time periods in addition to its function for permanently displaying hours, minutes and seconds. 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 typically at the 3 o'clock or 6 o'clock position. 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.) 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. 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.

This 44 mm chronograph model is crafted from 18K Sedna™ gold and includes a laser-ablated black ceramic bezel ring with a polished diving scale. 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.
