OMEGA Constellation

Omega's Constellation 131.20.29.20.52.002 is a 29 mm case in steel and yellow gold. The case measures 12 mm thick with a 31.2 mm lug-to-lug span, and the silver dial sits under a domed sapphire crystal with anti-reflective coating 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, giving 50 hours of power reserve. The watch shows the date and is set with diamonds, and the caseback is transparent so the movement can be viewed. It is fitted on a matching steel and yellow gold bracelet with a butterfly clasp that includes a comfort setting. The case is rated to 50 metres of water resistance.
