Vacheron Constantin: Overseas Perpetual Calendar Ultra-Thin Skeleton

After the success of the Oveseas Perpetual Calendar Ultra-Thin presented in 2019, this year Vacheron Constantin unveils the face of the 1120 QPSQ caliber through the sapphire crystal dial of the new Overseas Perpetual Calendar Ultra-Thin Skeleton.

In this new version, the Brand stages a real Haute Horlogerie show. Among the many components, the undisputed protagonists are 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. 

In addition to the skeleton technique, which consists of finely openworking a mechanical movement by hollowing out its components yet without compromising their reliability, Vacheron Constantin decorated the movement with 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 brushing, 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. 

Inside the gold case “41.5mm diameter X 8.1mm thickness”, the dial bears applied 18K 5N pink gold hour-markers, the Maltese cross emblem as well as day, date and month-counter rings. The calendar does not require any adjustment until March 1st 2100, neither for the day, date and month indications, nor for the moon phases.

Like all models in the Overseas collection, the new Perpetual Calendar Ultra-Thin Skeleton offers a modular touch via a simple and convenient bracelet/strap interchangeability system. Fitted with a gold bracelet, it also comes with two additional straps in blue alligator leather and blue rubber.
