Seamaster 300 Omega Master Co‑Axial 41 mm
Steel on leather strap
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 ceramic bezel has a Liquidmetal™ diving scale. The 41 mm stainless steel case is presented on a brown leather strap.
A transparent caseback makes it possible to see the anti-magnetic OMEGA Master Co-Axial calibre 8400 within.
The movement is unaffected by exposure to strong magnetic fields, even those greater than 1.5 tesla (15,000 gauss).
Label given to a watch which has undergone precision tests and received a certificate from an official body (COSC).
Self-locking crown, screwed into the tube of the case, used for highly water resistant divers' watches.
Transparent case backA 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.
