Originally launched in 1957 for divers and underwater professionals, the OMEGA Seamaster 300 has become a legendary tool watch. Over 60 years later, it has been reimagined with modern materials and movement technology—crafted for a new generation of explorers. This 41 mm stainless steel model features a black dial paired with a black oxalic anodized aluminium bezel, filled with vintage-toned Super-LumiNova for a classic dive watch aesthetic. The recessed hour markers, open numerals, and rhodium-plated hands are all coated with Super-LumiNova for excellent visibility in low light. Fitted with a rich brown leather strap, the watch also includes a sapphire crystal caseback that reveals the inner workings of the OMEGA Co-Axial Master Chronometer Calibre 8912—offering top-tier precision, anti-magnetism, and durability. This watch is unworn and will ship with the outer box, Omega display box, Warranty Card, Master Chronometer, serialized hang tag, and The Essential Guide.
