Editor's Notes


25 years after its first release, OMEGA have bundled all of their heritage and technology into this perfect watch collection. Capturing the ocean spirit, the OMEGA Seamaster Diver 300m Co‑Axial Master Chronometer collection can withstand some of the harshest environments. But don’t just take our word for it. The Master Chronometer status says it all.

Adorned with the collection’s famous waves, we love the chrome-coloured ceramic dial on this OMEGA Seamaster Diver 300m Co‑Axial Master Chronometer. How good does it look with the blue accents?
