Vacheron Constantin Overseas Perpetual Calendar Skeleton Boutique Edition – 4300V/120R-B642

Vacheron Constantin Overseas 4300V/120R‑B642 housed in a 41.5 mm rose gold case, the open worked dial reveals the fully skeletonized automatic Calibre 1120 QP SQ, a micro‑rotor movement with perpetual calendar complications: including day, date, month, leap‑year indication, and a moon‑phase. The moon‑phase display at 6 o’clock, charmingly rendered with twin gold moons against a star‑spangled sky, is balanced by subdials for the calendar functions and a discreet baton‑style hour and minute hands, all crafted in pink gold. It offers a 40‑hour power reserve, complete with the prestigious Hallmark of Geneva certification for fine finishing, protected by dual sapphire crystals and offering 50 m water resistance.
