Seamaster Master Co‑Axial Chronometer 41 mm

OMEGA first introduced the Seamaster 300 in 1957 - it was a watch designed especially for divers and professionals who worked underwater. More than half a century later, the timepiece makes a comeback in a completely upgraded and enhanced form, ready for a new generation of adventurers.

This Seamaster 300 has a sand-blasted black dial with 18K yellow gold hands coated with  "vintage" Super-LumiNova. The 18K yellow gold bezel has a ceramic bezel ring with a Ceragold™ diving scale. The 41 mm stainless steel case is presented on a brown leather strap.

A transparent caseback makes it possible to see the anti-magnetic OMEGA Master Co-Axial calibre 8400 within.
