OMEGA Constellation

Omega presents the Constellation 131.25.39.20.52.001 with a 39 mm case in steel and Sedna 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 for antireflection on both sides. Inside is the self-winding calibre 8800 with a Co-Axial escapement, a free sprung-balance and a silicon balance spring, offering 55 hours of power reserve. It is certified as a Master Chronometer by METAS and resists magnetic fields up to 15,000 gauss. The watch shows the date and is set with diamonds, and a transparent caseback reveals the movement. A bracelet in steel and Sedna gold closes with a butterfly clasp with comfort setting. Omega rates the case to 50 metres.
