OMEGA Constellation

Omega's Constellation 131.20.39.20.52.002 is a men's watch with a 39 mm case in steel and gold. The case measures 12.43 mm thick with a lug-to-lug of 41 mm, and the silver dial sits under a domed sapphire crystal treated on both sides against glare. Inside is the self-winding calibre 8800, a Co-Axial Master Chronometer movement certified by METAS and resistant to magnetic fields up to 15,000 gauss, with a free sprung-balance and silicon balance spring. Power reserve runs to 55 hours. The watch carries a date function and is set with diamonds, and a sapphire display back shows off the movement's Geneva waves in arabesque. It comes on a matching steel and gold bracelet fitted with a butterfly clasp with comfort setting. Water resistance stands at 50 metres.
