Official description

 

The Constellation Observatory marks a defining moment in OMEGA’s pursuit of precision.

This 39.4 mm polished-brushed model in 18K Moonshine™ Gold features the distinctive faceted “dog-leg” lugs accompanied by a bezel with clear-cut facets. It is presented on a yellowish 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 18K Moonshine™ Gold dial is presented with sun-brushed centre and opaline facets with 8 lustrous hand-guillochégrooves. The revamped kite-form indexes are fully diamond-polished, matched with diamond-polished dauphine hands, crafted from 18K Moonshine™ Gold.

The watch is driven by OMEGA’s calibre 8915, 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 18K Moonshine™ Gold skeletonised rotor embellished by an applied medallion featuring the laser-engraved Constellation Observatory emblem in contrasting finish.The watch is presented in a special marquetry box featuring the Constellation Observatory emblem.
