Omega Museum Collection 1951 Cosmic: a rare triple-calendar tribute in solid 18k rose gold

The Omega Museum Collection 1951 Cosmic is a limited-edition reissue drawn from Omega's mid-century "Cosmic" triple-date moonphase, reinterpreted for the modern collector. Produced as part of Omega's prestigious Museum Collection, this reference honors a landmark design while presenting it in a warm solid 18k rose gold case. It is a piece defined by restraint, horological heritage, and genuine scarcity.

The deep blue dial frames a triple calendar complication — day, date, and month — paired with an elegant moonphase indicator. Power comes from the Omega automatic Caliber 2601, a self-winding movement with full calendar functions, housed in a square rose gold case. With just 1,951 examples made worldwide, the Cosmic remains one of the more sought-after entries in the Museum Collection.
