Seamaster 300 Seamaster Yellow gold Master Chronometer 234.63.41.21.99.002

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 (METAS).
