The 2026 Omega Constellation Observatory 140.13.39.21.01.001 draws inspiration from vintage Constellation designs while utilizing modern movement engineering. Housed in a 39.4 mm O-Megasteel case with signature dog-leg lugs, the watch features a 3-bar water-resistant construction, a sapphire caseback, and a black ceramic 'pie-pan' style dial with 18K white gold markers. It is powered by the METAS-certified Master Chronometer calibre 8914, a 3.5 Hz self-winding movement with a 60-hour power reserve, magnetic resistance up to 15,000 gauss, and a time-zone function. The piece is completed by a glossy black leather strap and a skeletonized rotor showcasing the Constellation Observatory emblem.
