OMEGA De Ville Prestige

Omega's De Ville Prestige 434.20.34.20.02.001 measures 34 mm across in steel and Sedna gold. The case stands 10.1 mm thick with a lug-to-lug span of 39.38 mm, and the silver dial sits under a domed sapphire crystal with antireflective treatment inside. Self-winding calibre 8800 drives the watch, a Co-Axial movement certified as a Master Chronometer by METAS and resistant to magnetic fields up to 15,000 gauss. Power reserve runs to 55 hours, and a free sprung-balance with silicon spring keeps time. The date sits on the dial, and a transparent caseback shows the movement's rhodium-plated finish and Geneva waves in arabesque. Steel and Sedna gold link the bracelet, closed with a butterfly clasp. Omega rates the case to 30 metres.
