Vacheron Constantin is right up there as one of the few passionate, luxury watchmakers existing today, who have mastered the art of producing exceptional timekeepers for centuries. The maison’s love for craftsmanship and excellence in horological complications has led to the creation of two very elegant Overseas timepieces, both exemplifying technical and aesthetic perfection. Meet the Overseas Perpetual Calendar Ultra-Thin and Overseas Perpetual Calendar Ultra-Thin Skeleton.
Overseas Perpetual Calendar Ultra-Thin
The new Vacheron Constantin Overseas Perpetual Calendar Ultra-Thin is presented for the first time in an 18K 5N pink gold case and bracelet or alligator leather / blue rubber strap, along with a translucent blue lacquered dial. A spirited combination that endows this model with a distinctive new personality. The watch’s precious metal bracelet features links inspired by the shape of the Maltese cross, the emblem of the maison.
The brilliance of the gold extends to the blue dial, whose hour-markers, hands and moon discs are also made of 18K 5N pink gold. While the blue-lacquered gold dial captivates the eye with its sunburst satin finish, the counters are distinguished by their snailed decoration, while the gold-rimmed minute-rack opts for a velvet finish. These delicate decorations contrasting with the vertical-brushed of the case endow the blue dial with its full strength of character.
With a thickness of just 8.1mm, the new Overseas Perpetual Calendar Ultra-Thin is remarkably slim. CALIBRE 1120 QP/1, a mechanical self-winding movement developed and manufactured by Vacheron Constantin beats inside the 41.5mm case. It drives the hours, minutes, perpetual calendar function – with the day of the week, date, month and leap year shown on a 48-month counter – as well as moon phases.
CALIBRE 1120 QP/1 is 4.05mm thick and comprises 276 components that keep track of calendar irregularities with no need for correction until the year 2100. Beating at a frequency of 19,800 vibrations per hour the watch delivers a comfortable 40-hours of power reserve.

Overseas Perpetual Calendar Ultra-Thin Skeleton
Ladies and Gentlemen, brace yourselves to experience pure brilliance. In this new gold-clad version, Vacheron Constantin highlights the expression of Haute Horlogerie values with its skeletonised dial, allowing the wearer to experience the thrill of the inner workings of the extremely thin (4.05 mm) openworked perpetual calendar movement and the marvel of how the gears capture time with utmost precision. The transparent caseback also stages a fascinating watchmaking show starring the gear trains and the NAC-treated oscillating weight with its segment in 22K gold, which is also openworked for the first time in the Overseas collection so as to highlight its stylised design shaped like a Maltese cross.
Skeletonisation is an art in itself. The technique involves finely openworking a mechanical movement by hollowing out its components yet without compromising their reliability. It is an extremely complex undertaking: a quest for transparency coupled with highly sophisticated skills mastered by very few watchmaking artisans. Today, Vacheron Constantin is one of the rare Manufactures capable of openworking calibres as complex as perpetual calendars and ultra-thin movements. For the new Overseas Perpetual Calendar Ultra-Thin Skeleton all components of the 1120 QPSQ calibre have been hollowed out, finished and decorated, so as to exalt the functional beauty of the mechanism.
To fully match the style of Overseas, the movement has benefited from special finishing work, entirely performed by hand. Multiple skills have thus come into play so as to endow the mechanism with the sought-after aesthetic perfection. Straight-graining the surfaces to give them a satin-brushed finish; bevelling straight lines and curves to make the create light effects; circular b rushing, sunburst finishing, circular-graining and polishing to ensure varied reliefs: while the use of all these ancestral craftsmanship techniques has served to highlight the beauty of the components, an anthracite grey shade obtained by means of an NAC electrolytic treatment gives the mechanism a very modern face. The dial bears 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 gaze to roam freely through the heart of the movement and admire its hand-crafted finishing.
While watches with simple calendars – indicating the day, date and month – require constant adjustments according to months with 28, 29 and 30 days, the Overseas Perpetual Calendar ultra- thin skeleton watch will not require any intervention until March 1, 2100, neither for its calendar indications nor for the moon phases. Achieving such a performance with a movement that slim – yet housing 276 components – called for authentic feats of design and miniaturisation.
Like all models in the Overseas collection, this exceptional watch offers a modular touch via a simple and convenient bracelet/strap interchangeability system. Fitted with a gold bracelet whose satin- brushed half Maltese cross-shaped links underline the elegance of the timepiece, it also comes with two additional straps in blue alligator leather and blue rubber.
