Platinum on leather strap
Sorry, but this product is currently not available. Make sure you join the waiting list.
OMEGA first introduced the Seamaster 300 in 1957 as a watch especially for divers. On this contemporary model, the legendary design has been transformed for luxury style.
The 41 mm case has been made from platinum-gold and features a green ceramic bezel with a platinum Liquidmetal™ diving scale. Most captivating of all is the watch’s deep green dial, which is made from the precious stone malachite. It includes 18K white gold hands that are filled with “vintage” Super-LumiNova.
Presented on a green leather strap, the watch is driven by the OMEGA Master Chronometer Calibre 8913, certified at the industry’s highest standard by the Swiss Federal Institute of Metrology (METAS).
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).
Liquidmetal is an alloy which is considerably harder than stainless steel yet bonds seamlessly with ceramics. The blended materials are particularly resistant to scratching and corrosion.
Screw-in crown Screw-in crown
Self-locking crown, screwed into the tube of the case, used for highly water resistant divers' watches.
Transparent case back Transparent case backA transparent case back - frequently made of sapphire - makes it possible to see the movement inside the watch.
Unidirectional rotating bezel 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.
