Circa 1997 Omega Constellation ladies quartz watch in brushed stainless steel and yellow gold-capped case featuring a diamond-set bezel of approximately 0.30 carats F-G/VVS1-VVS2, a mother-of-pearl dial with single cut diamond hour markers, gold Dauphine hands, and an integrated two-tone bracelet with signed deployant clasp. Case measures 22.5mm; bracelet length 6 5/8 inches; total weight 49 grams.

The Constellation bracelet numbered 865 features the model's signature integrated design — brushed stainless steel center links capped with polished yellow gold edges that flow directly into the tonneau case without visible lugs, creating the seamless, architectural silhouette the Constellation collection has been celebrated for since its debut. The diamond-set yellow gold bezel frames a luminous mother-of-pearl dial set with individual diamond hour markers, giving this watch a level of gem-set refinement that elevates it well above a standard Constellation reference. The signed deployant clasp numbered 6553/865 and the Constellation observatory logo caseback confirm full Omega authenticity throughout.

The Omega Constellation was introduced in 1952 as the brand's flagship precision timepiece, born from Omega's string of victories at the Geneva Observatory chronometry trials and named to commemorate that achievement. By the 1990s the Constellation had evolved into one of the most recognizable luxury dress watch collections in the world, beloved for its integrated bracelet design, precious metal detailing, and gem-set dial options that appealed to a sophisticated female clientele. The caliber 1456 quartz movement powering this reference was engineered to Omega's exacting Swiss standards, delivering consistent accuracy in a movement slim enough to complement the Constellation's elegant proportions. Collectors and watch enthusiasts prize 1990s Constellation references for their honest luxury — genuine precious metal construction, factory diamond setting, and the irreplaceable mother-of-pearl dial material that gives each watch a unique, organic luminosity no painted surface can replicate. This particular reference, with its VVS diamond bezel and full diamond dial markers, represents the Constellation at its most refined and collectible.
