Omega Seamaster 300 41mm yellow gold on leather strap

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 18K yellow gold and features a blue ceramic bezel with an OMEGA Ceragold diving scale. Most captivating of all is the watch’s deep blue dial, which is made from the precious stone lapis lazuli. It includes 18K yellow gold hands that are filled with “vintage” Super-LumiNova.
Presented on a blue 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.

Master Chronometer Certified
Guaranteeing the Swiss industry’s highest standard of precision, performance and magnetic-resistance, as set by the Swiss Federal Institute of Metrology.
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.
