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. This model has a 40 mm stainless steel case with a diamond-paved bezel and is presented on a blue leather strap. The domed blue patterned dial includes a date window at 6 o'clock as well as hands and indexes in 18K white gold. Inside, this De Ville Trésor is powered by the OMEGA Master Co-Axial Calibre 8910 and is certified as a Master Chronometer at the industry’s highest standard of precision, chronometric performance and magnetic resistance.
