Vacheron Constantin Overseas Perpetual Calendar Blue Sapphire 4307V/220G-236C

Vacheron Constantin Overseas Perpetual Calendar Ultra-Thin Skeleton High Jewellery reference 4307V/220G-236C is a highly exclusive, off-catalogue masterpiece crafted from 18K white gold. This extraordinary sports timepiece measures 41.5 mm in diameter. Its most distinguishing visual hallmark is a spectacular, six-sided bezel set with 60 factory baguette-cut blue sapphires, which intricately frames a fully openworked, skeletonized dial. Through the sapphire crystal, it reveals the exceptional hand-finishing and complex mechanics of the in-house Calibre 1120 QPSQ/1 self-winding movement, which features a velvet-finished blue minutes track and dark multi-counter rings to track the day, date, month, leap year, and moon phase. Completing its elite luxury aesthetic is an integrated white gold bracelet built with Maltese cross-inspired links and a versatile quick-change system.
