Omega Seamaster 300 41mm steel on steel

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.
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 caseback
A transparent caseback – 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.
