OMEGA De Ville Trésor

The Omega De Ville Trésor 435.13.40.21.02.001 has a steel case measuring 40 mm across. It stands 10.05 mm thick, with a lug-to-lug span of 44.8 mm. The silver dial sits beneath a sapphire crystal treated with anti-reflective coating on both sides. Inside is the manual-winding calibre 8910, a Master Chronometer movement with Co-Axial escapement and a silicon balance spring, certified by METAS and resistant to magnetic fields up to 15,000 gauss. Power reserve runs to 72 hours. The date function is set into the dial, and a sapphire caseback lets the movement's Geneva waves in arabesque show through. A black alligator leather strap with a steel pin buckle completes the watch. Water resistance is modest, rated to 30 metres.
