Vintage Omega Ladies' 14k or 18k White Gold and Diamond Marquise-Shaped Cocktail Watch

This is a luxury vintage women's cocktail watch by Omega, likely dating from the 1960s or early 1970s. The piece features a distinctive marquise-shaped (navette) case crafted in white gold, which is heavily embellished with a halo of round brilliant-cut diamonds. The dial is a sunburst silver or champagne tone with minimalist applied stick indices and the Omega emblem at the 12 o'clock position. The case is flanked by ornate leaf-like diamond-set lugs that transition into a sophisticated multi-strand double-wheat or foxtail link mesh bracelet. A safety chain is visible attached to the clasp area, indicating high-value construction designed to prevent loss. The craftsmanship is indicative of mid-century high-jewelry horology, involving intricate metalwork and pave-set gemstone accents. Condition-wise, the watch shows signs of age-appropriate patina and light surface scratches on the metal and crystal, but the stones appear secure. The movement is likely a manual-wind mechanical caliber, typical for Omega watches of this diminutive size during this era. The overall aesthetic is elegant and formal, representing the pinnacle of feminine evening wear from the period.
