OMEGA Constellation

Omega Constellation 131.58.29.20.53.003 measures 29 mm across in Sedna gold, a warm rose alloy the brand reserves for its higher-end pieces. The case stands 12.2 mm thick with a lug-to-lug span of 31.2 mm, compact proportions suited to a woman's wrist. A domed sapphire crystal with anti-reflective treatment on both sides covers the blue dial. Inside is the self-winding calibre 8701, a Master Chronometer movement with Co-Axial escapement, a silicon balance spring and a 50-hour power reserve, certified by METAS to resist magnetic fields up to 15,000 gauss. The watch is set with diamonds, and a date function sits alongside a display back that shows the gold rotor and balance bridge. A blue alligator leather strap closes with a Sedna gold pin buckle. Omega rates the case to 50 metres.
