OMEGA Seamaster 300 41mm Watch 234.30.41.21.01.001

The OMEGA Seamaster 300 41mm (Ref. 234.30.41.21.01.001) revives the original 1957 Seamaster 300 design through a completely upgraded form that retains the heritage aesthetic whilst incorporating contemporary Master Chronometer technology. The black oxalic anodized aluminium bezel with vintage Super-LumiNova diving scale and recessed hour markers with open numerals create deliberate period references that distinguish the Seamaster 300 from the more modern Diver 300M line within OMEGA’s diving watch family.

At 41mm with 13.85mm thickness through stainless steel construction, this provides refined diving watch proportions with 48mm lug-to-lug ensuring comfortable daily wear whilst the black dial with rhodium-plated hands and vintage Super-LumiNova throughout maintains authentic heritage character. The ergonomic stainless steel bracelet with foldover clasp and comfort setting provides secure daily wear whilst the transparent sapphire caseback enables appreciation of the movement.

The Co-Axial Master Chronometer Calibre 8912 delivers 60-hour power reserve with 15,000 gauss magnetic resistance through METAS certification whilst the free-sprung balance with silicon balance spring and two barrels mounted in series provide consistent power delivery. The time zone function, Geneva waves finishing, and screw-in crown completing the specification that earned Master Chronometer status through all eight METAS tests.

The domed sapphire crystal with anti-reflective inner treatment ensures optimal clarity whilst the 300m water resistance and unidirectional rotating bezel validate genuine diving capability. The vintage Super-LumiNova choice over contemporary white Super-LumiNova is a deliberate aesthetic decision that gives the Seamaster 300 its own character within the broader OMEGA diving watch range.
