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).

Master Chronometer Certified
Guaranteeing the Swiss industry’s highest standard of precision, performance and magnetic-resistance, as set by the Swiss Federal Institute of Metrology (METAS).
Screw-in crown
Self-locking crown, screwed into the tube of the case, used for highly water resistant divers' watches.
Time zone function
Allows the hour hand to be easily adjusted to different time zones without stopping the watch.
Unidirectional rotating bezel
