Editor's Notes

Sleek dials, helium escape valves, and the oh-so-popular wave pattern applied around the open caseback are just some of the features found on the OMEGA Seamaster Diver 300m collection. Inspired by the ocean, the Seamaster features some of OMEGA’s most advanced technology to date.

We love the somewhat sporty combination of the stainless steel case and blue rubber strap, offering the perfect balance of sophistication and versatility on this OMEGA Diver 300m Co‑Axial Master Chronometer. Plus, see the beating heart of this watch through the open caseback.
