Omega Diver 300M Co-Axial Master Chronometer Chronograph 44 mm Blue Dial (210.60.44.51.03.001)

Description

Since 1993, the Seamaster Professional Diver 300M has enjoyed a legendary following. This 44 mm chronograph is a Numbered Edition model and is built from grade 2 titanium, 18K Sedna™ gold and tantalum, which can be found on the base of the bezel and the middle links of the bracelet.

The 18K Sedna™ gold bezel ring features a laser-ablated diving scale, while the polished blue ceramic [ZrO2] dial is distinguished by laser-ablated waves, a date window at 6 o’clock, and subdial rings with touches of 18K Sedna™ gold.

The side of each case includes an 18K Sedna™ gold plate engraved with each unique Numbered Edition number. Turning the watch over reveals an OMEGA Seahorse, which has been laser-engraved and lacquered white on the sapphire crystal. Through the glass, you can see the OMEGA Co-Axial Master Chronometer Calibre 9900, certified by the Swiss Federal Institute of Metrology (METAS).

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 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 (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).

• Numbered edition

  A watch series each of whose pieces is numbered sequentially in the order it is produced.

• 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 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.
