Celebrating Vacheron Constantin’s 270th year of continuous operation, this 18K 5N pink gold watch is set with 80 round-cut diamonds. Centred on the dial is a moon phase that needs adjustment only once per 122 years, its a star-studded sky subtly echoed by the alligator strap. This watch, a limited release of 270 pieces, boasts a meticulously worked mother-of-pearl dial, decorated with a specially created Maltese cross pattern. Its manual-winding movement bears a discreet anniversary signature and a "côte unique" finish. The Traditionnelle Collection’s characteristic styling is found in the stepped, round case and lugs, slender bezel and fluted caseback, railway-type minute track and Dauphine-type hour and minute hands.
