Omega Diver 300M Co-Axial Master Chronometer 42 mm Grey Dial (210.60.42.20.99.001)

Description

Since 1993, the Seamaster Diver 300M has enjoyed a legendary following.

This 42 mm model is a Limited Edition of 2,500 pieces and features a brushed case made from grade 2 titanium, with a crown, bezel ring and helium escape valve in 18K Sedna™ gold. In contrast, OMEGA has used tantalum to create the base of the bezel for a distinctive blue-grey tone.

The titanium dial features positive sun-brushed waves. The skeleton hands and raised indexes are 18K Sedna™ gold and are filled with white Super-LumiNova.

The watch is presented on a grade 2 titanium bracelet with tantalum and 18K Sedna™ gold links. An image of the OMEGA Seahorse can be found on the transparent caseback, through which you can see the OMEGA Master Chronometer Calibre 8806 inside.

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).

• 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.)

• Limited edition (2,500)

  A series of watches whose production run is determined in advance of production and limited to a set number.

• 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.
