Vacheron Constantin Traditionnelle Chronograph Perpetual Calendar 5000T/000P-B048

About This Watch

The Vacheron Constantin Traditionnelle Chronograph Perpetual Calendar unites two major complications — a column-wheel chronograph and a perpetual calendar — in a single movement. The caliber 1142 QP is manually wound, with the chronograph mechanism providing elapsed time measurement while the perpetual calendar tracks day, date, month, moon phase, and leap year autonomously until 2100. The platinum case adds the density and prestige appropriate for a grand complication of this caliber. The blue dial organizes the multiple displays with remarkable legibility: chronograph sub-dials at 3 and 9, calendar displays interspersed among them, and moon phase at 6. Geneva Seal certification ensures every component meets the most exacting finishing standards. The combination of chronograph and perpetual calendar is one of the most coveted grand complication pairings, requiring extraordinary engineering to prevent the chronograph mechanism from interfering with the calendar's precise operation. This watch represents the upper reaches of Vacheron Constantin's traditional complication capability.
