Seamaster 300 Omega Master Co‑Axial 41 mm
Steel ‑ Sedna™ Gold on leather strap
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 Sedna™ gold hands coated with "vintage" Super-LumiNova. The 18K Sedna™ 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.
All OMEGA watches are delivered with a 5-year warranty that covers the repair of any material or manufacturing defects. Please refer to the operating instructions for specific information about the warranty conditions and restrictions.
The movement is unaffected by exposure to strong magnetic fields, even those greater than 1.5 tesla (15,000 gauss).
Ceragold is the result of a process that allows the incrustation of 18K gold into a ceramic bezel. The bezels made of ceramic and the Ceragold are perfectly smooth to the touch.
Label given to a watch which has undergone precision tests and received a certificate from an official body (COSC).
