OMEGA Constellation

Omega's Constellation 131.10.34.20.02.001 measures 34 mm in steel, a compact case suited to either wrist. It stands 11.7 mm thick with a lug-to-lug span of 37 mm, and the silver dial sits under a domed sapphire crystal with antireflective treatment on both sides. The self-winding calibre 8802 drives the watch, a Co-Axial movement with a free sprung-balance and silicon balance spring, certified as a Master Chronometer and resistant to magnetic fields up to 15,000 gauss. Small seconds appear at six o'clock, and the date is also shown. Power reserve runs to 55 hours. The steel bracelet closes with a butterfly clasp, and a transparent caseback shows off the rhodium-plated rotor and Geneva waves beneath. Water resistance is rated to 50 metres.
