2025 Vacheron Constantin 4300V/220R-B642 Overseas Perpetual Calendar Ultra-Thin Skeleton Rose Gold 41.5mm

The Vacheron Constantin Overseas Perpetual Calendar Ultra-Thin Skeleton 4300V/220R-B642 combines haute horlogerie with the sporty character of the Overseas collection, featuring a 41.5mm case and integrated bracelet crafted in 18K 5N pink gold. Its transparent sapphire dial reveals the intricately openworked Calibre 1120/3 QPSQN/1 beneath, accented by blue calendar counters and a moon-phase display for striking contrast and exceptional depth. Measuring just 8.1mm thick, the ultra-thin automatic movement provides hours, minutes, day, month, leap-year indication, moon phase, and a perpetual calendar engineered to remain accurate until 2100. Finished to the exacting standards of the Hallmark of Geneva and visible through the sapphire caseback, this sophisticated Overseas pairs exceptional mechanical complexity with Vacheron Constantin’s refined finishing and versatile integrated design.
