Vacheron Constantin Overseas Perpetual Calendar Ultra-Thin 4300V/120G-B102

About This Watch

The Vacheron Constantin Overseas Perpetual Calendar Ultra-Thin is an extraordinary feat: a grand complication housed within a sporty, water-resistant luxury watch measuring just 8.1mm thick. The caliber 1120 QP/1 is an evolved version of the brand's legendary ultra-thin perpetual calendar movement, adapted for the more demanding Overseas environment with improved shock resistance. The 18k white gold case and integrated bracelet give it a cool, contemporary presence while the Maltese cross bezel maintains the Overseas identity. The blue lacquered dial arranges the perpetual calendar displays with remarkable legibility: day and month in twin apertures below 12 o'clock, date by central hand, moon phase at 6 o'clock, and leap year at 3 o'clock. Like all Overseas models, it comes with interchangeable straps, though the white gold bracelet will likely remain the strap of choice for most owners. This watch occupies a unique niche: no other luxury sports watch combines a perpetual calendar with such extreme thinness and Geneva Seal finishing. It is a statement piece for the collector who wants everything — complication, sportiness, elegance — in a single watch.
