Omega Diamond / Yellow Gold Cocktail Ladies Watch

A refined example in ‘New Old Stock’ conditions of mid-century Omega design, this 1961 ladies cocktail watch balances elegance with technical nuance. Crafted in 18k yellow gold to the brand’s higher manufacturing standard, it houses the elusive calibre 690—a rare, ultra-small manual movement prized by collectors for its precision and scarcity. The white gold bezel is discreetly adorned with 16 brilliant cut diamonds, adding just the right measure of formality without overstatement. Measuring modestly on the wrist, this piece remains purposeful and wearable, true to its era. Offered here as a full set, including original inner and outer boxes along with the purchase certificate, it represents an increasingly uncommon level of completeness. In hand, the quality distinction of this example becomes immediately clear—setting it apart from 98% of Omega’s timepieces from the same era.
