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 case in 18K Sedna™ gold, which is presented on a grey leather strap. The domed grey enamel dial has been achieved with a Grand Feu technique and includes enamel prints, as well as hands and indexes in 18K Sedna™ gold.
Inside, this De Ville Trésor is powered by the OMEGA Co-Axial Master Chronometer Calibre 8929 and is certified at the industry’s highest standard of precision, chronometric performance and magnetic resistance.
