In 1957, OMEGA first launched the Seamaster 300 - specially designed for divers and all professionals working underwater. After more than sixty years, the collection has been completely renewed and today includes this special model created in the brand's bronze alloy. The 41 mm case and bezel are crafted in 9K Bronze Gold, while the brown ceramic bezel ring features a graduated scale with a Super-LumiNova insert. The bronze-colored dial features recessed hour markers and numerals with Super-LumiNova inserts, as well as gold-colored bronze PVD hands. Equipped with a brown leather strap with a 9K Bronze Gold buckle, the timepiece is equipped with a transparent sapphire crystal caseback that allows you to admire the OMEGA Co-Axial Master Chronometer caliber 8912.
