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.

Where do we start with our favourite things about this model? It's got to be the wave edged open caseback where you can see the beating heart that is the Master Chronometer Calibre 8800.
