OMEGA De Ville Prestige

Omega's De Ville Prestige 434.20.42.22.02.001 measures 42 mm across in steel and Sedna gold. The case stands 12.27 mm thick with a lug-to-lug span of 48.95 mm, and the silver dial sits under a domed sapphire crystal treated with antireflective coating inside. Calibre 8936 drives the watch, a self-winding movement with Co-Axial escapement that carries Master Chronometer certification from METAS and resists magnetic fields to 15,000 gauss. It runs on a free sprung-balance with silicon balance spring and stores 60 hours of power reserve. Beyond the date function, the movement also handles a time zone display, and a transparent caseback lets the finishing show through. The steel and Sedna gold bracelet closes with a butterfly clasp. Water resistance is modest: the case is rated to 30 metres.
