Omega Tresor Manual Winding Watch - 40mm Stainless Steel Silver Dial

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, which is presented on a black leather strap. The domed opaline silvery 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 Co-Axial Master Chronometer Calibre 8910 and is certified at the industry’s highest standard of precision, chronometric performance and magnetic resistance.

Calibre Omega 8901: Manual-winding movement with Co-Axial escapement. Certified Master Chronometer, approved by METAS, resistant to magnetic fields reaching 15,000 gauss. Free-sprung balance with silicon balance spring. Rhodium plated finish with Geneva waves in arabesque.

FEATURES

Chronometer: Label given to a watch which has undergone precision tests and received a certificate from an official body (COSC).

Date: The day of the month, displayed in a window on a watch dial at the 3 or 6 o’clock position, or within a subdial at 9 o'clock.

Master Chronometer Certified: Guaranteeing the Swiss industry’s highest standard of precision, performance and magnetic-resistance, as set by the Swiss Federal Institute of Metrology (METAS).

Transparent case back: A transparent case back - frequently made of sapphire - makes it possible to see the movement inside the watch.
