Vacheron Constantin Overseas Perpetual Calendar Ultra-Thin Skeleton

Vacheron Constantin expands its Overseas collection by launching the brand new Overseas Perpetual Calendar Ultra-Thin Skeleton model. Dressed in an 18K 5N all-gold case, this new timepiece perpetuates the travel-driven spirit of the Overseas collection and combines the refinement of precious metal with the nobility of its ultra-thin open-worked complication movement. The 41.5 mm-diameter case houses the prestigious Calibre 1120 QPSQ, which combines an extraordinary aesthetic with Haute Horlogerie values.

The prestige of a precious metal case and bracelet is complemented by the extreme sophistication of an ultra-thin open-worked perpetual calendar movement, giving the timepiece a contemporary and sophisticated look. The self-winding Calibre 1120 QPSQ has been much appreciated by collectors for its reliability, its extreme precision and its performance.

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 open-worked for the first time in the Overseas collection so as to highlight its stylised design shaped like a Maltese cross.

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. 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 ultrathin skeleton watch will not require any intervention until March 1, 2100, neither for its calendar indications nor for the moon phases.
