OMEGA De Ville Ladymatic

The Omega De Ville Ladymatic 425.30.34.20.55.002 is a steel watch measuring 34 mm across. The case stands 11.95 mm thick with a lug-to-lug of 41.6 mm, and the white dial sits under a domed sapphire crystal treated with antireflective coating on both sides. Inside is the self-winding calibre 8520, a chronometer movement with a Co-Axial escapement and a free sprung-balance fitted with a silicon balance-spring. It runs with 50 hours of power reserve. The watch is set with diamonds and shows the date, with a screw-down crown and a display back revealing the movement. A steel bracelet closes with a butterfly clasp. Omega rates the case to 100 metres.
