OMEGA Constellation

The Omega Constellation 131.10.39.20.02.001 measures 39 mm across in steel. 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 with antireflective treatment on both sides. Inside is the self-winding calibre 8800, a Co-Axial Master Chronometer movement certified by METAS and resistant to magnetic fields of 15,000 gauss, with a free sprung-balance and silicon balance spring. Power reserve runs to 55 hours. A date function sits on the dial, and the display back shows the movement finishing of Geneva waves in arabesque with a rhodium-plated finish. The steel bracelet closes with a butterfly clasp that includes a comfort setting. Rated 5 bar, the case holds up to 50 metres of water resistance.
