OMEGA Constellation Observatory 39.4mm Watch
Product Details
The OMEGA Observatory marks a defining moment in OMEGA’s pursuit of precision.
This 39.4 mm polished and brushed model in O-Megasteel features the collection’s signature faceted “dog-leg” lugs, paired with a bezel distinguished by crisp, clean-cut facets. It is presented on a black glossy leather strap with a polished buckle.
The “Pie Pan” dial is reminiscent of the original 1952 Constellation, with dodecagonal facets, a transferred OMEGA logo, and an applied Constellation star. The black ceramic dial is defined by its polished centre and polished facets, presented without grooves for a sleek, refined look. The redesigned kite-shaped indexes are fully diamond-polished and paired with matching kite-form hands, all crafted in 18K white gold.
Powering the watch is OMEGA’s calibre 8914, the world’s first two-hand movement to achieve Master Chronometer certification approved by METAS. Visible through the sapphire crystal caseback, the movement features a rhodium-plated, skeletonised rotor adorned with an applied medallion, showcasing the laser-engraved Constellation Observatory emblem in a contrasting finish.
