Omega Constellation

About this reference

The Omega Constellation reference 168005 was produced during the 1960s, featuring the chronometer-rated caliber 561 or 564 automatic movements. While the reference is common in stainless steel and yellow gold, the 18k white gold execution is rare and sought by collectors for its "C-Shape" case design attributed to Gerald Genta. This specific variant typically features a sunburst silver or "pie-pan" dial with white gold indices and matching baton hands. The case construction includes a screw-down caseback with the Observatory medallion in relief. On the secondary market, 18k white gold examples generally command between $6,000 and $12,000 depending on the presence of an integrated white gold bracelet and overall condition. A notable production detail is the use of "Sigma" markings on later dials, indicating the use of solid gold components, which often increases the realized price at specialized watch auctions.
