OMEGA Constellation

Omega presents the Constellation 131.25.29.20.99.002, a 29 mm case in steel and yellow gold. The case measures 12 mm thick with a lug-to-lug span of 31.2 mm, sized for a woman's wrist. A domed sapphire crystal with antireflective treatment on both sides covers the yellow dial. Inside is the self-winding calibre 8700, a Master Chronometer movement with a Co-Axial escapement and a silicon balance spring, certified to resist magnetic fields up to 15,000 gauss and good for 50 hours of power reserve. The watch is set with diamonds and shows the date, and a display back exposes the movement. The bracelet is steel and yellow gold, closed with a butterfly clasp with comfort setting. The clasp helps keep the case sealed to 50 metres of water resistance.
