OMEGA De Ville Ladymatic

The Omega De Ville Ladymatic, reference 425.30.34.20.57.004, has a steel case measuring 34 mm across. The case stands 11.95 mm thick with a lug-to-lug span of 41.6 mm, and a domed sapphire crystal with antireflective treatment on both sides covers the black dial. Inside is the self-winding calibre 8520, a chronometer movement with a Co-Axial escapement and a free sprung-balance system using a silicon balance spring, giving 50 hours of power reserve. The screw-down crown protects the movement, and a date function sits on the dial. The watch is set with diamonds. A sapphire display back shows off the finishing, with Geneva waves in arabesque. It closes on a steel bracelet with a butterfly clasp. Water resistance holds at 100 metres.
