OMEGA Constellation

Omega's Constellation reference 131.55.29.20.55.003 has a round yellow gold case with a diameter of 29 mm. The case is 12 mm thick and measures 31.2 mm from lug to lug. A domed sapphire crystal with anti-reflective treatment on both sides covers the white dial. Omega rates the case to 50 metres. The self-winding calibre 8701 is a Master Chronometer with a 50 hour power reserve, and a display back exposes it. The dial has a date window, and the Constellation is set with diamonds. A yellow gold bracelet is fitted, closed by a butterfly clasp with a comfort setting.
