OMEGA De Ville Trésor

The Omega De Ville Trésor 435.13.40.21.03.002 is a steel watch measuring 40 mm across. The case stands 10.05 mm thick with a lug-to-lug of 44.8 mm. Inside is the manual-winding calibre 8926, a Master Chronometer movement with co-axial escapement, resistant to magnetic fields up to 15,000 gauss and certified as a chronometer. A blue dial sits under a sapphire crystal treated with anti-reflective coating on both sides, and small seconds appear at six o'clock. The free-sprung balance runs with a silicon spring and two barrels in series, giving 72 hours of power reserve. Through the transparent caseback the rhodium-plated finish, decorated with Geneva waves in arabesque, is visible. The blue alligator leather strap closes with a steel pin buckle, and the case keeps a modest 30 metre water resistance.
