OMEGA first introduced the Seamaster 300 in 1957 - designed especially for divers and professionals who worked underwater. More than 60 years later, the collection has been completely upgraded, and includes this special model created in OMEGA’s own bronze alloy. The 41 mm case and bezel are crafted from 9K Bronze Gold, while the brown ceramic bezel ring includes a diving scale in vintage Super-Lumi Nova. On the bronze dial, you’ll find recessed hour markers and open numerals with Super-Lumi Nova, as well as PVD Bronze Gold coloured hands. Presented on a brown leather strap with a 9K Bronze Gold buckle, this timepiece includes a transparent sapphire crystal caseback, enabling a clear view of the OMEGA Co-Axial Master Chronometer Calibre 8912.
