From Watches & Wonders 2020: Vacheron Constantin’s Overseas Perpetual Calendar Ultra-Thin Skeleton

The new watch from Vacheron Constantin will not require any intervention—neither for its calendar indications nor for the moon phases—until March 1, 2100

The world’s oldest watch manufacture in continuous production for over 265 years, Vacheron Constantin, highlights the expression of haute horlogerie values at this year’s Watches and Wonders Geneva online platform. The maison explored new territory for its Overseas collection with the latest Overseas Perpetual Calendar Ultra-Thin Skeleton.

For one, “skeletonization” is regarded by connoisseurs as a watchmaking complication in itself and is indeed a special mark of craftsmanship. This technique, which consists of finely open-working a mechanical movement by hollowing out its components without compromising their reliability, is an extremely complex undertaking.

Hence, while retaining its dynamic design, the aesthetic of this new watch is transfigured by a sapphire dial inviting the wearer on a journey to the heart of the extremely thin 4.05mm open-worked perpetual calendar movement. In this new gold-clad version, the prestige of a precious metal case and bracelet is now complemented by the maison with a contemporary and horologically sophisticated look.

Up front, the dial is entirely open-worked, which is a feat in itself as it reveals its mechanical intricacies beneath a transparent sapphire crystal. On top of the dial are applied 18K 5N pink gold hour-markers, the Maltese cross emblem as well as day, date and month-counter rings. This design ensures that the watch is perfectly legible while allowing the wearer’s gaze to roam freely through the heart of the movement and admire its hand-crafted finishing.

On the other hand, the transparent caseback also stages a fascinating watchmaking show with open-worked gear trains and oscillating weight—for the first time in the Overseas collection—in order to highlight the stylized design shaped like a Maltese cross and also the self-winding Calibre 1120 QPSQ, which has been hollowed out, finished and decorated, so as to exalt the functional beauty of the mechanism.

Speaking of the Overseas Perpetual Calendar’s mechanism, the movement behind this watch will not require any intervention—neither for its calendar indications nor for the moon phases—until March 1, 2100. Meanwhile, like all models in the Overseas collection, this exceptional watch offers a modular touch via a simple and convenient bracelet/strap interchangeability system.

Above all, in a quest for transparency coupled with highly sophisticated skills mastered by very few watchmaking artisans, the new Vacheron Constantin’s Overseas Skeleton Perpetual Calendar watch surely perpetuates the travel-driven spirit of the collection.
