OMEGA Constellation

Omega's Constellation 131.20.39.20.02.001 measures 39 mm across in steel and Sedna gold. The case stands 12.43 mm thick with a lug-to-lug span of 41 mm, and the silver dial sits under a domed sapphire crystal treated against reflections on both sides. Inside is the self-winding calibre 8800, a 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 date function is set at three o'clock, and a sapphire display back shows the movement's Geneva waves in arabesque. A steel and Sedna gold bracelet closes with a butterfly clasp fitted with a comfort setting. The case carries a rating of 5 bar, or 50 metres.
