Characterised by its thin and classic gold case, the tresor was first launched by OMEGA in 1949 and housed the legendary 30mm calibre. More than half a century later, the De Ville tresor 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 tresor is powered by the anti-magnetic OMEGA Master Co-Axial calibre 8511 – a unique manual winding movement.
