Overseas Perpetual Calendar Ultra-Thin in 18K Pink Gold

Discover the absolute pinnacle of sports luxury and Haute Horlogerie with the Vacheron Constantin Overseas Perpetual Calendar Ultra-Thin (Ref. 4300V/220R-B547). Masterfully combining the robust, travel-inspired architecture of the iconic Overseas collection with one of watchmaking’s most prestigious and demanding complications, this masterpiece is designed for the modern connoisseur.

Iconic Design Meets Ultra-Thin Elegance

The striking 41.5 mm case is crafted from solid 18K 5N pink gold, featuring the collection’s signature six-sided bezel inspired by the Maltese cross. Despite housing a highly complex perpetual calendar mechanism, the watch boasts an astonishingly slender profile of just 8.1 mm, ensuring it slips effortlessly beneath a tailored cuff while maintaining a commanding presence. A sapphire crystal caseback allows for an unobstructed view of the masterful mechanics inside.

The Captivating Translucent Blue Dial

Perfectly complementing the warmth of the pink gold is a mesmerising translucent blue lacquered dial. Finished with a sunburst satin base and a velvet-finished flange, it captures and reflects light beautifully. The dial features perfectly balanced sub-dials displaying the day, date, month, and leap year cycle, alongside a stunning moon phase indicator at 6 o’clock. The 18K pink gold hour markers and hands are treated with a luminescent coating, ensuring exceptional legibility in all conditions.

The Legendary Calibre 1120 QP/1

At the heart of this timepiece lies the legendary Calibre 1120 QP/1, an ultra-thin self-winding mechanical movement bearing the prestigious Hallmark of Geneva (Poinçon de Genève). Measuring a mere 4.05 mm in thickness, this extraordinary calibre intelligently accounts for leap years and will not require a calendar adjustment until the year 2100. It features a spectacular 22K gold openworked oscillating weight, shaped like a compass rose, and delivers a power reserve of approximately 40 hours.

Ultimate Versatility: The Interchangeable System

A defining feature of the modern Overseas collection, this timepiece offers unparalleled versatility through Vacheron Constantin’s ingenious interchangeable strap system. It is delivered with three beautifully crafted options: a solid 18K 5N pink gold bracelet with half-Maltese cross links, a sporty blue rubber strap, and an elegant blue Mississippiensis alligator leather strap. This allows you to seamlessly adapt the watch to any environment or occasion in seconds, entirely without the need for tools.
