WATCHMAKER｜Vacheron Constantin Ultra-Thin Perpetual Calendar: The Pinnacle of Craftsmanship in a 4.05mm Movement

The Vacheron Constantin Ultra-Thin Perpetual Calendar watch showcases the exquisite craftsmanship of the ultra-thin Calibre 1120 QP/1 movement. This self-winding mechanism, with a mere thickness of 4.05 millimeters, encapsulates one of the most challenging complications in watchmaking—the perpetual calendar and moon phase display. Like a miniature mechanical computer, it automatically adjusts the intricate calendar without requiring manual correction until the year 2100. Comprising 276 components, including 36 jewels, the Calibre 1120 QP/1 movement stands as a paragon of miniaturization, epitomizing Vacheron Constantin's horological artistry.
