OMEGA De Ville Prestige

Omega's De Ville Prestige 434.20.40.20.02.001 has a 40 mm case in steel and Sedna gold. The case measures 9.93 mm thick with a lug-to-lug of 46.26 mm, and a domed sapphire crystal with antireflective treatment covers the silver dial. Inside is the self-winding calibre 8800, a Master Chronometer movement with Co-Axial escapement and a silicon balance spring resistant to magnetic fields up to 15,000 gauss. Power reserve runs to 55 hours. The date function sits on the dial, and a transparent caseback shows the movement finished with rhodium plating and Geneva waves in arabesque. A steel and Sedna gold bracelet closes with a butterfly clasp. Water resistance is limited to 30 metres, so this is not a watch for diving.
