Constellation Observatory

Automatic | 39.4 MM | O‑MEGASTEEL on alligator | 140.13.39.21.01.001

The OMEGA 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 black glossy leather strap on polished buckle.

The “Pie-Pan” dial is a reminiscent of the original 1952 Constellation with dodecagonal facets, with transferred OMEGA logo and applied Constellation star. The black ceramic dial is presented with polished centre and polished facets without 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.
