OMEGA Constellation

Omega's Constellation 131.25.29.20.63.001 is a women's model measuring 29 mm across in steel and Sedna gold. The case stands 12 mm thick with a lug-to-lug span of 31.2 mm and carries a brown dial. A domed sapphire crystal with anti-reflective treatment on both sides covers the dial, and the caseback is transparent, showing the movement beneath. That movement is the self-winding calibre 8700, a Co-Axial Master Chronometer certified by METAS with a silicon balance spring and 50 hours of power reserve. The watch is set with diamonds and includes a date function. Steel and Sedna gold link to form the bracelet, closed with a butterfly clasp fitted with a comfort setting. Water resistance reaches 50 metres.
