Omega Diver 300M Co-Axial Master Chronometer 42 mm Black Dial (210.22.42.20.01.002)

Description

Since 1993, the Seamaster Professional Diver 300M has enjoyed a legendary following. Today’s modern collection has embraced that famous ocean heritage and updated it with OMEGA’s best innovation and design.

This 42 mm model is crafted from stainless steel and 18K Sedna™ gold, and includes a black ceramic bezel with a Ceragold™ diving scale. The dial is also polished black ceramic and features laser-engraved waves and a date window at 6 o’clock.

The skeleton hands and raised indexes are 18K Sedna™ gold and are filled with white Super-LumiNova, while the helium escape valve has been given a conical design.

The watch is presented on a black rubber strap and is driven by the OMEGA Master Chronometer Calibre 8800, 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).

• 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.

• 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.
