Vacheron Constantin Traditionnelle Perpetual Calendar Skeleton

The Vacheron Constantin Traditionnelle Perpetual Calendar Skeleton (ref. 43172/000P-9236) is a beautiful creation that puts its mechanics on full display. Its 39mm platinum case frames a fully skeletonized movement, revealing the intricacies of the perpetual calendar in motion.

The finely engineered caliber displays the day, date, month, and 48‑month leap‑year cycle, automatically accounting for the varying lengths of months and leap years. As a result, the calendar will not require manual correction until the year 2100.

Hand-finished to meet the rigorous standards of the Geneva Seal, this Vacheron Constantin is a truly wearable piece of horological art for those who appreciate exceptional mechanical craftsmanship. This well-preserved example is offered complete with its Certificate of Origin and Guarantee, Geneva Seal Certificate, user manual, presentation box, and outer packaging.
