Art Deco Blancpain “cocktail” 18k White Gold And Diamond Wristwatch

Ladies “cocktail” bracelet watch in the Art Deco style, most likely designed and manufactured during the 1930s–1940s. Such jewellery watches were conceived to combine refined aesthetics with discreet timekeeping, intended for formal and evening wear.
The watch is accompanied by its original Blancpain certificate, issued by Rayville S.A., successors to Blancpain, dated 1962, corresponding to the date of sale or market release, in line with Swiss horological practice of the period.

The watch is entirely crafted in 18k white gold, including the flexible bracelet composed of finely woven links.
The circular case features a diamond-set bezel, with natural diamonds arranged in a surrounding motif, using traditional claw and grain-setting techniques. The small dial is protected by a domed crystal and houses a manual-winding mechanical movement, with ruby jewels referenced on the certificate.

The design presents a harmonious balance between jewellery and timepiece. The restrained sheen of white gold contrasts subtly with the brilliance of the diamonds, framing the dial without excess. The bracelet flows naturally around the wrist, and the clasp is discreetly integrated into the overall structure.

The watch is offered with its original Blancpain certificate, complete with period wax seal. The document confirms manufacture within the brand’s own workshops, the use of high-quality materials, and precise adjustment. The Rayville S.A. designation reflects Blancpain’s historical commercial name used in the mid-20th century.

Very good overall condition. The white gold shows an even, consistent patina. The diamonds are well preserved and securely set. The bracelet remains supple and well proportioned. The certificate displays age-related wear consistent with its date.

An elegant Art Deco ladies bracelet watch combining Swiss watchmaking and fine jewellery craftsmanship, produced by one of Switzerland’s oldest manufactures. A complete and documented example, suitable for collectors and connoisseurs.
