Vacheron Constantin Overseas Perpetual Calendar Skeleton Ultra-thin

Vacheron Constantin Overseas Perpetual Calendar Ultra-Thin Skeleton reference 4300V/120G-B946 is a masterful fusion of sporty elegance and haute horlogerie complexity. Encased in an ultra-thin 41.5mm 18K white gold profile that stands at just 8.1mm thick, this timepiece houses the entirely skeletonized, automatic caliber 1120 QPSQ/1, which is visibly finished with modern gray NAC-treated bridges and an openworked 22K gold rotor shaped like a Maltese cross. The transparent sapphire dial features complex yet highly legible calendar indications, including a 48-month leap year sub-dial at 12 o'clock, date at 3 o'clock, day of the week at 9 o'clock, and an astronomical moon phase displaying twin gold moons against a star-studded sky at 6 o'clock.
