Greatly appreciated by connoisseurs, the 4.05 mm in-house Calibre 1120 QP gives life to a new Traditionnelle perpetual calendar ultra-thin designed for women's wrists. This 36.5 mm-diameter model reflects Vacheron Constantin's grand tradition of horological complications, notably interpreted through ultra-thin versions. Its 18K white gold case bears the identity codes of the Traditionnelle collection featuring meticulous handcrafted finishing. Its gem-set bezel and its dial graced with delicately shimmering mother-of-pearl have been meticulously designed to ensure optimum legibility of the calendar indications.
