OMEGA Seamaster Diver 300M Chronometer 42mm Blue Watch

Keanes Code: 5233051


The 42mm Seamaster Diver 300M features a stainless steel case and bracelet, boasting a ceramic dial in OMEGA's Summer Blue with a gradient finish reflecting water resistance.

The dial showcases the iconic wave pattern, while a blue ceramic bezel with Summer Blue enamel diving scale surrounds it. Rhodium-plated skeleton hands and light blue Super-LumiNova-filled indexes adorn the dial.

On the case back, a commemorative stamped Seamaster logo reveals a trident-bearing Poseidon and two seahorses, representing OMEGA's 1956 original and current designs. Inside, the watch houses OMEGA's Co-Axial Master Chronometer calibre 8800, certified at the highest level by the Swiss Federal Institute of Metrology (METAS).
