A Secret in Gold
Created in 1942, this extraordinary Vacheron Constantin reference 4266 embodies the artistry of the secret watch, where fine jewelry conceals the precision of Swiss watchmaking. Its bold, geometric 18k pink-gold bracelet opens to reveal a discreet dial, reflecting the sculptural elegance of mid-century design.
Of particular significance is its bracelet, attributed in accompanying historical documentation to celebrated Geneva casemaker Marc Houriet, whose craftsmanship was sought by both Vacheron Constantin and Patek Philippe. Believed to have been produced in very limited numbers, the design is further distinguished by a related sapphire-set example reportedly preserved in Vacheron Constantin's Geneva museum collection.
A rare expression of the maison's jewelry-making heritage, this example is accompanied by a Vacheron Constantin Extract from the Archives confirming its 1942 manufacture, additional historical documentation, and a travel case. Original box and warranty papers are not included.
