About This Piece

One of the best all-round dive watches out there (in our humble opinion), it's water resistant to 300m so you’ll never need to take it off. And why would you want to?

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.

We love this OMEGA Diver 300m Co‑Axial Master Chronometer for the stunning combination of stainless steel and yellow gold touches as well as the open caseback where you can see the Master Chronometer Calibre 8800 at work.
