De Ville Tresor Master Chronometer Power Reserve

From the retailer listing

Characterised by its thin and elegant case, the Trésor 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 burgundy leather strap, this model has a polished 40 mm stainless steel case and a bezel paved with 72 full-cut diamonds. The domed burgundy dial includes a Power Reserve display at 12H, a Small Seconds display at 6H, along with hands and domed indexes in 18K white gold. Inside, this De Ville Trésor is powered by the OMEGA Co-Axial Master Chronometer Calibre 8934 and is certified at the industry’s highest standard of precision, chronometric performance and magnetic resistance.
