Vacheron Constantin: Overseas Perpetual Calendar Ultra-Thin White Gold

Presented for the first time in 2020 in rose gold, Vacheron Constantin introduces two new editions of the Overseas perpetual calendar ultra-thin at Watches and Wonders 2021: a skeletonized version and one with a blue dial.

The respective perpetual calendar movements of these two new editions are each framed by a 41.5 mm white gold case. The ultra-thin 4.05 mm 1120 QPSQ/1 skeleton movement is visible from the front, while Calibre 1120 QP/1 can be admired through the caseback of the solid-dial version. 

OVERSEAS PERPETUAL CALENDAR ULTRA-THIN SKELETON

In this model all the components of Calibre 1120 QPSQ/1 have been hollowed out, finished and decorated in such a way as to accentuate the functional beauty of the mechanism. The NAC-coated oscillating weight with its 22K gold segment has also been openworked to highlight its stylised design inspired by the shape of the Maltese cross. 

The finishing work is meticulous: from the straight- graining of the surfaces (to lend a satin-brushed look to the chamfered straight lines) and the curves (to create light effects) to circular brushing, sunburst finishing, circular-graining and polishing (to vary the depth effects), every aspect bears the imprint of the artisans’ golden touch. 

OVERSEAS PERPETUAL CALENDAR ULTRA-THIN

Unmistakable thanks to the hexagonal bezel that evokes the Maltese cross, this model comes with a translucent lacquered dial with facetted and luminescent gold hour-markers and hands. Its blue lacquered dial with a sunburst satin finish, displaying the hours, minutes, perpetual calendar indications and the moon phases. 

This timepiece is driven by the emblematic Calibre 1120 QP/1, an ultra-thin self-winding mechanical movement barely 4.05 mm thick, beating at a frequency of 2.75 Hz and endowed with an approximately 40-hour power reserve. Its perpetual calendar copes smoothly with calendar irregularities and will require no correction until 2100. This calibre is also enhanced by multiple finishing operations hand-crafted in accordance with Haute Horlogerie traditions: Côtes de Genève striped motif, straight-graining, chamfering and circular-graining. In a touch representing the height of chic style, the caseback reveals a 22K gold oscillating weight adorned with a compass rose symbolising the spirit of travel and exploration. 

Like all models in the Overseas collection, the new Vacheron Constantin perpetual calendar ultra-thin are equipped with an ingenious patented device that allows you to replace the strap / bracelet in seconds without using any tools.
