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.

Framing the open caseback, where you can see the OMEGA Master Chronometer Calibre 9900 at work, you’ll also find the intricate wave design, a nod to the ocean heritage of the Seamaster.
