Constellation Observatory 39.4 mm, O‑MEGASTEEL on alligator

The Constellation Observatory marks a defining moment in OMEGA’s pursuit of precision. This 39.4 mm polished-brushed model in O-Megasteel features the distinctive faceted “dog-leg” lugs accompanied by a bezel with clear-cut facets. It is presented on a dark green leather strap on polished buckle. The “Pie-Pan” dial is a reminiscent of the original 1952 Constellation with dodecagonal facets, with applied OMEGA logo and Constellation star. The green dial is presented with sun-brushed centre and opaline facets with 8 embossed grooves. The revamped kite-form indexes are fully diamond-polished, matched with diamond-polished dauphine hands, crafted from 18K white gold. The watch is driven by OMEGA’s calibre 8914, the world’s first two-hand watch to achieve Master Chronometer certification approved by METAS. The movement is visible through the sapphire crystal caseback, revealing a rhodium-plated skeletonised rotor embellished by an applied medallion featuring the laser-engraved Constellation Observatory emblem in contrasting finish.
