OMEGA De Ville Prestige

Omega's De Ville Prestige 434.20.40.20.52.001 measures 40 mm in steel and yellow gold. The case stands 10.36 mm thick with a lug-to-lug span of 46.26 mm, and the watch is set with diamonds. A self-winding calibre 8800 drives it, certified as a Master Chronometer and resistant to magnetic fields up to 15,000 gauss, with a free sprung-balance and silicon balance spring. Power reserve runs to 55 hours. The silver dial sits under a domed sapphire crystal with anti-reflective treatment, and a date function is paired with a transparent caseback that shows the movement. A yellow gold bracelet closes with a butterfly clasp. Water resistance is limited to 30 metres, so this is a watch for the office rather than the pool.
