Vintage Girard-Perregaux / Galt & Bro. Ladies Diamond Cocktail Watch

A sophisticated mid-20th-century ladies' cocktail wristwatch, double-signed by the prestigious Swiss manufacturer Girard-Perregaux and the historic Washington D.C. retailer, Galt & Bro. The timepiece features a rectangular stainless steel or white gold cases (hallmark not clearly visible, but typical of the era), measuring approximately 15mm in width excluding the fluted setting crown. The silver-tone dial exhibits Arabic numerals at 12, 3, 6, and 9 o'clock, interspersed with applied dot indices, and is fitted with leaf-shaped hour and minute hands. A primary design highlight is the ornate filigree scrollwork at the top and bottom lugs, each set with what appear to be three single-cut diamonds, totaling six stones for the piece. The watch is integrated with a 'cobra' or 'serpentine' style expandable link bracelet. The condition shows moderate antique patina, with visible tarnishing on the case edges and minor scratches on the acrylic crystal. The dial shows light foxing consistent with an age ranging from the 1940s to the early 1950s. The craftsmanship reflects the high-quality mechanical movement standards of Girard-Perregaux, coupled with the luxury retail branding of Galt, known for serving the U.S. presidential families.
