OMEGA Constellation

The Omega Constellation 131.10.29.20.52.001 has a steel case measuring 29 mm across. It stands 12 mm thick with a lug-to-lug span of 31.2 mm, compact proportions suited to the women's line. The watch is set with diamonds and the domed sapphire crystal carries anti-reflective treatment on both sides. Inside is the self-winding calibre 8700, a Master Chronometer certified movement with a silicon balance spring and resistance to magnetic fields up to 15,000 gauss; power reserve runs to 50 hours. A date function is included, and the transparent caseback shows the movement finishing of Geneva waves in arabesque. The steel bracelet closes with a butterfly clasp fitted with a comfort setting. Water resistance reaches 50 metres.
