OMEGA Constellation Observatory 39.4mm Watch
Product Details
The OMEGA Observatory represents a milestone in OMEGA’s pursuit of precision. This 39.4 mm model, crafted in polished and brushed O-Megasteel, features signature faceted “dog-leg” lugs and a sharply defined bezel, paired with a dark grey leather strap and polished buckle.
Its iconic “Pie-Pan” dial pays tribute to the original 1952 Constellation, with a silvery opaline centre, dodecagonal facets, and refined detailing including diamond-polished kite-shaped indexes and hands in 18K Sedna™ Gold.
Powered by OMEGA’s calibre 8914—the first two-hand movement to achieve Master Chronometer certification by METAS—the watch showcases exceptional precision. The movement is visible through a sapphire crystal caseback, revealing a skeletonised rotor with a finely engraved Constellation Observatory emblem.
