234.30.41.21.01.001 - In 1957, OMEGA first introduced the Seamaster 300 - a watch designed specifically for divers and professionals who worked underwater. Over 60 years later, the timepiece has been completely redesigned and given an optimized shape for a new generation of adventurers. This 41mm stainless steel model features a black dial and a black oxalic acid anodized aluminum bezel with a diving scale filled with vintage Super-LumiNova. The recessed hour indices, open numerals and hands also feature Super-LumiNova. The timepiece is held on the wrist by an ergonomic stainless steel bracelet and features a transparent sapphire crystal caseback through which the OMEGA Co-Axial Master Chronometer caliber 8912 can be seen.
