Seamaster Co‑Axial Master Chronometer 41 mm

OMEGA first introduced the Seamaster 300 in 1957 - designed especially for divers and professionals who worked underwater. More than 60 years later, the timepiece has been completely upgraded with an enhanced form that is ready for a new generation of adventurers.

This 41 mm stainless steel model includes a blue dial and a blue oxalic anodized aluminium bezel with its diving scale filled with vintage Super-LumiNova. The recessed hour markers and open numerals feature Super-LumiNova, which is also present on the rhodium-plated hands.

Presented on an ergonomic stainless steel bracelet, this timepiece includes a transparent sapphire crystal caseback, enabling a clear view of the OMEGA Co-Axial Master Chronometer Calibre 8912.
