Vacheron Constantin Overseas Perpetual Calendar Ultra-Thin Skeleton 41 mm Rose Gold with Brass Dial

The Vacheron Constantin Overseas Perpetual Calendar Ultra-Thin Skeleton 41 mm in 18K rose gold reveals the full poetry of perpetual motion through an openworked masterpiece of haute horlogerie. A symbol of both transparency and timelessness, this exceptional timepiece unites the spirit of adventure with the artistry of precision craftsmanship.

The openworked brass dial showcases the intricate Caliber 1120 QPSQ/1, a self-winding perpetual calendar movement that measures only 4.05 mm thick. Every bridge and wheel is meticulously skeletonized and hand-finished, offering a mesmerizing view of the perpetual mechanism that tracks day, date, month, leap year, and moon phase with unwavering accuracy — all without adjustment until the year 2100.

Against the architectural interplay of rose gold and the metallic shimmer of the skeletonized brass, the moon phase aperture at 6 o’clock provides a poetic counterpoint, symbolizing the passage of celestial time. The sapphire crystal caseback reveals the 22K gold oscillating weight, adorned with the iconic wind rose — an emblem of Vacheron Constantin’s devotion to travel and discovery.

At just 8.1 mm in thickness, this ultra-thin perpetual calendar is remarkably elegant, complemented by the integrated rose gold bracelet with its polished and satin-brushed finishes. Enhanced with the interchangeable strap system, it offers versatility befitting modern connoisseurs of fine watchmaking.

The result is a transparent expression of perpetual artistry — where form, function, and fine mechanics coexist in perfect harmony.
