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 blue dial with 18K Sedna™ gold hands coated with "vintage" Super-LumiNova. The 18K Sedna™ gold bezel has a Ceragold™ ring and diving scale.
The 41 mm grade 5 titanium case is presented on a grade 5 titanium and 18K Sedna™ gold bracelet. A transparent caseback makes it possible to see the anti-magnetic OMEGA Master Co-Axial calibre 8400 within.

Screw-In Crown
Self-locking crown, screwed into the tube of the case, used for highly water resistant divers' watches.
Chronometer
Label given to a watch which has undergone precision tests and received a certificate from an official body (COSC).
Transparent Caseback
A transparent caseback - frequently made of sapphire - makes it possible to see the movement inside the watch.
Time Zone Function
Allows the hour hand to be easily adjusted to different time zones without stopping 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.
