Trésor Omega Master Co‑Axial 40 mm
Yellow gold on leather strap
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 18K yellow gold case is presented on a brown leather strap with an 18K yellow gold buckle. This De Ville Trésor is powered by the anti-magnetic OMEGA Master Co-Axial calibre 8511 - a unique manual winding movement.
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.
