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 polished 40 mm 18K yellow gold case, which is presented on a green leather strap. The domed green dial includes a Small Seconds display at 6H, along with hands and domed indexes in 18K yellow gold. Inside, this De Ville Trésor is powered by the OMEGA Co-Axial Master Chronometer Calibre 8927 and is certified at the industry’s highest standard of precision, chronometric performance and magnetic resistance.
