Trésor Omega Master Co‑Axial 40 mm
Sedna™ gold on leather strap
Note: watch no longer available
Characterised by its thin and classic gold case, the Trésor was first launched by OMEGA in 1949 and housed the legendary 30mm calibre. More than half a century later, the De Ville Trésor has been reintroduced, equipped with one of the most advanced mechanical movements the brand has ever unveiled.
This model has a domed white mother-of-pearl dial with polished 18K gold hands and a date window at 6 o'clock. The 40 mm 18K Sedna™ gold case, with its diamond-set bezel, is presented on a brown leather strap with a polished buckle. This De Ville Trésor is powered by the anti-magnetic OMEGA Master Co-Axial calibre 8511 - a unique manual winding movement.
The movement is unaffected by exposure to strong magnetic fields, even those greater than 1.5 tesla (15,000 gauss).
Label given to a watch which has undergone precision tests and received a certificate from an official body (COSC).
