Omega De Ville Tresor 40mm steel on leather strap

Characterised by its thin and elegant case, the Tr’sor line was first launched by OMEGA in 1949 and housed the legendary 30mm calibre. More than half a century later, it continues to impress with one of today’s most advanced mechanical movements.
Presented on a grey leather strap, this model has a polished 40 mm stainless steel case and a bezel paved with 72 full-cut diamonds. The domed silvery crystal dial includes a Small Seconds display at 6H, along with hands and domed indexes in 18K white gold.
Inside, this De Ville Tr’sor is powered by the OMEGA Co-Axial Master Chronometer Calibre 8926 and is certified at the industry’s highest standard of precision, chronometric performance and magnetic resistance.
