Overseas Perpetual Calendar Skeleton Ultra-Thin

Vacheron Constantin Overseas Perpetual Calendar Ultra-Thin 4300V/220R The Vacheron Constantin Overseas Perpetual Calendar Ultra-Thin Skeleton – Ref. 4300V/220R is a pinnacle expression of modern haute horlogerie, combining extreme mechanical sophistication with refined sport-luxury aesthetics. Crafted in 18k rose gold, this reference showcases one of the most advanced perpetual calendar movements ever produced in an exceptionally elegant and wearable form. The fully skeletonized dial offers a breathtaking view of the perpetual calendar mechanism, displaying day, date, month, leap year, and a beautifully integrated moon phase. Blue sapphire calendar discs contrast sharply against the warm rose-gold architecture, creating depth, clarity, and a distinctly contemporary visual identity. At its heart beats the legendary Caliber 1120 QPSQ, one of the world’s thinnest automatic perpetual calendar movements. Hand-finished to the uncompromising standards of the Geneva Seal, the movement exemplifies Vacheron Constantin’s mastery of ultra-thin watchmaking and traditional haute horlogerie decoration. The watch is completed by the integrated 18k rose gold Overseas bracelet, inspired by the Maltese cross and engineered for exceptional comfort and balance. Despite its complexity, the 4300V retains the versatility and elegance that define the Overseas collection. The reference 4300V/220R is not simply a perpetual calendar — it is a transparent statement of heritage, innovation, and absolute refinement.
