Description

Characterised by its thin and classic gold case, the Trésor line 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 silvery opaline dial with a domed vintage "clous de Paris" structure and a date window at 6 o'clock. The 40 mm white gold case is presented on a black leather strap with an 18K white gold buckle. This De Ville Trésor is powered by the anti-magnetic OMEGA Master Co-Axial calibre 8511 - a unique manual winding movement.
