OMEGA Constellation Observatory

The Omega Constellation Observatory 140.13.39.21.01.001 has a steel case measuring 39.4 mm across. Thickness comes in at 12.23 mm with a lug-to-lug span of 47.2 mm. The black dial sits under a domed sapphire crystal, bevelled and treated with anti-reflective coating on both sides. Inside is the self-winding calibre 8914, a Master Chronometer movement certified by METAS with resistance to magnetic fields up to 15,000 gauss and a 60 hour power reserve. The watch also includes a time zone function, and a sapphire caseback reveals the rhodium-plated rotor and bridges finished with Geneva waves. It comes on a black alligator leather strap with a grained calf leather lining, closed by a steel pin buckle. The pin buckle secures a case that stays water resistant to 30 metres.
