OMEGA Constellation Observatory

Omega's Constellation Observatory 140.53.39.21.99.004 is a men's watch with a 39.4 mm white gold case. Thickness runs to 12.23 mm and lug-to-lug measures 47.2 mm. The case is finished in Canopus Gold, Omega's white gold alloy, and pairs with a silver dial under a domed sapphire crystal treated with anti-reflective coating on both sides. Inside is the self-winding calibre 8915, a Co-Axial Master Chronometer movement certified by METAS and resistant to magnetic fields up to 15,000 gauss, with a time zone function and 60 hours of power reserve. The rotor and balance bridge show Geneva waves in arabesque, visible through the sapphire display back. A blue alligator strap closes with a white gold pin buckle, and the case holds a 30 metre water resistance rating.
