De Ville Trésor Master Co‑Axial Chronometer 40 mm

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 white 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.
