Omega Seamaster 300 Master Co-Axial Chronometer 41 mm Black Dial (233.30.41.21.01.001)

Description

OMEGA first introduced the Seamaster 300 in 1957 – it was a watch designed especially for divers and professionals who worked underwater.

More than half a century later, the timepiece makes a comeback in a completely upgraded and enhanced form, ready for a new generation of adventurers. This Seamaster 300 has a sand-blasted black dial with rhodium-plated hands coated with “vintage” Super-LumiNova. The polished ceramic bezel ring has a Liquidmetal™ diving scale.

The 41 mm brushed and polished stainless steel case is presented on a matching bracelet. A transparent caseback makes it possible to see the anti-magnetic OMEGA Master Co-Axial calibre 8400 within.

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).

• Screw‑in crown

  Self-locking crown, screwed into the tube of the case, used for highly water resistant divers’ watches.

• 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.
