The Omega De Ville Ladymatic Co-Axial Chronometer (ref. 425.35.34.20.57.002) is a refined ladies' luxury watch featuring a 34mm 316L stainless steel case with a wave-patterned ring and white ceramic inner casebody. The elegant blue mother-of-pearl dial is decorated in a supernova pattern with diamond-set indexes and a date window at 3 o'clock, all viewed through a domed scratch-resistant sapphire crystal with anti-reflective coating.

The diamond-set bezel frames the case, which measures 11.95mm thick with a lug-to-lug distance of 41.60mm. The watch is presented on a matching stainless steel bracelet secured by a butterfly clasp.

Powering the watch is Omega's self-winding Calibre 8520, featuring the patented Co-Axial escapement for greater precision and reduced friction, a silicon Si14 balance spring for superior shock and magnetic resistance, twin barrels in series providing approximately 50 hours of power reserve, and a frequency of 25,200 vph (3.5 Hz) with 28 jewels. The movement is COSC-certified as a chronometer and is visible through the transparent caseback. Water resistance is rated to 10 bar (100m / 330ft).
