OMEGA De Ville Ladymatic

Omega's De Ville Ladymatic ref. 425.25.34.20.55.004 is a 34 mm watch in steel and Sedna gold. The case measures 11.95 mm thick with a lug-to-lug span of 41.6 mm, and the white dial sits under a domed sapphire crystal with antireflective treatment on both sides. Inside is the self-winding calibre 8520, a chronometer movement with Co-Axial escapement, a free sprung-balance and a silicon balance spring, giving 50 hours of power reserve. The watch shows the date and is set with diamonds. A screw-down crown protects the movement, and a sapphire display back shows it off. The steel and Sedna gold bracelet closes with a butterfly clasp. Omega rates the case to 100 metres.
