Vacheron Constantin Overseas Perpetual Calendar Ultra-Thin Skeleton 41 mm Pink Gold

The Vacheron Constantin Overseas Perpetual Calendar Ultra-Thin Skeleton 41 mm in 18K pink gold is a breathtaking display of openworked artistry and mechanical brilliance. It unites the timeless elegance of the Overseas collection with the intricate transparency of haute horlogerie — a timepiece where every detail, every bridge, and every wheel becomes a celebration of craftsmanship.

The fully openworked dial reveals the beating heart of the Caliber 1120 QPSQ/1, a self-winding perpetual calendar movement that measures just 4.05 mm in thickness. Through its carefully skeletonized bridges and NAC-treated components, one can admire the flawless architecture and rhythmic harmony of the perpetual mechanism — tracking day, date, month, leap year, and moon phase without interruption until 2100.

The blue-toned skeleton dial contrasts beautifully with the pink gold case and bracelet, reflecting light with remarkable depth. The 22K gold oscillating weight, visible through the sapphire crystal back, is engraved with a wind rose — a signature of the Overseas spirit and its tribute to global travel and exploration.

With its ultra-thin 8.1 mm profile and interchangeable strap system, this timepiece blends technical mastery with effortless versatility. The result is not just a watch, but a sculptural expression of perpetual motion — refined, rare, and resoundingly modern.
