Co‑Axial Master Chronometer 41 mm

This 41 mm Seamaster 300, with its symmetrical case in polished and brushed stainless steel, has a matching bracelet.

The varnished dial, in OMEGA’s own Summer Blue, has a gradient finish to reflect the watch’s level of water resistance. In keeping with the colour code, OMEGA has filled the rhodium-plated hands, recessed hour markers, and open numerals with a unique light blue Super-LumiNova.

Turning the watch over reveals a stamped commemorative Seamaster logo depicting a trident-bearing Poseidon and two seahorses: OMEGA’s 1956 original and the brand’s current design. Behind which sits OMEGA’s Co-Axial Master Chronometer calibre 8912, certified at the industry’s highest level by the Swiss Federal Institute of Metrology (METAS).
