OMEGA Constellation

Omega's Constellation 131.25.29.20.53.001 is a women's model with a 29 mm case in steel and gold. The case measures 12.2 mm thick with a lug-to-lug span of 31.2 mm, and the blue dial sits beneath a domed sapphire crystal treated against glare on both sides. Inside is the self-winding calibre 8700, a Master Chronometer certified movement built with a silicon balance spring and resistant to magnetic fields up to 15,000 gauss, with 50 hours of power reserve. The watch is a chronometer with a date function and is set with diamonds. A display back reveals the movement. The bracelet, in matching steel and gold, closes with a butterfly clasp that includes a comfort setting. Omega rates the case to 50 metres of water resistance.
