In 1957, OMEGA first launched the Seamaster 300 - specially designed for divers and all professionals working underwater. After more than sixty years, the timepiece returns with a completely updated and renewed shape, ready to accompany a new generation of adventurers. This 41mm stainless steel model features a black dial and a black anodized aluminum bezel with a graduated scale with a vintage Super-LumiNova insert. The recessed indexes, the numbers and the rhodium-plated hands feature Super-LumiNova inserts. Equipped with an ergonomic stainless steel bracelet, the timepiece is equipped with a transparent sapphire crystal caseback that allows you to admire the OMEGA Co-Axial Master Chronometer caliber 8912.
