OMEGA Constellation Observatory

Omega's Constellation Observatory 140.53.39.21.99.001 measures 39.4 mm across in Moonshine gold. The case stands 12.23 mm thick with a lug-to-lug span of 47.2 mm, and the domed sapphire crystal carries anti-reflective treatment on both sides. Inside is the self-winding calibre 8915, a Master Chronometer movement certified by METAS with a Co-Axial escapement and resistance to magnetic fields up to 15,000 gauss. Two barrels mounted in series give 60 hours of power reserve. The yellow dial pairs with a time zone function, and a transparent caseback shows the Moonshine gold rotor and Geneva-waved balance bridge. A green alligator leather strap closes with a pin buckle in matching gold. The case carries a 30 metre water resistance rating.
