Vacheron Constantin – Overseas Perpetual Calendar Ultra-Thin Skeleton in White Gold and Overseas Perpetual Calendar Ultra-Thin in White Gold

Vacheron Constantin expands their Overseas collection by adding two new sporty-chic perpetual calendar watches in white gold

The two latest ultra-thin perpetual calendar iterations – a skeleton version and another with a blue dial – come in a new white gold case. They embody an art of diversity reflected in the three interchangeable bracelet/straps delivered with each watch.

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.

These timepieces demonstrate an equally admirable ability to adapt to the demands of modern life with their interchangeable bracelet/straps in white gold, blue alligator leather and blue rubber. The leather and rubber straps are each fitted with an 18K white gold pin buckle and an ingenious patented device enables tool-free changes in just seconds.

In 2016, the Overseas collection was reinvented with a view to exploring new horizons. A new aesthetic signature and new calibres were unveiled. One of the most recent embodiments of this approach was the perpetual calendar ultra-thin skeleton model introduced in 2020 in a pink gold version and rewarded with a prize by the Grand Prix d’Horlogerie de Genève (GPHG) that same year.

Perfectly embodying the technical and aesthetic expertise of the Maison, this watch is now presented in a new white gold interpretation exclusively available from Vacheron Constantin boutiques.

The sapphire crystal of this version reveals a truly magnificent sight: 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 open-worked 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.

Skeleton-working calibres as complex as this perpetual calendar with its 276 components, while ensuring both legibility and reliability, is an integral part of the Maison’s expertise. The gaze is naturally drawn to the intricate inner workings of the movement, while also reading the time on the applied 18K white gold hour-markers as well as the day of the week, date and month indications on the dial counters.

Whereas watches indicating the day of the week, date and month require constant adjustments in step with months of 28, 29 and 30 days, the Overseas perpetual calendar ultra-thin skeleton watch will not require the slightest intervention until the year 2100 – an ultimate user-friendly feature.

The Overseas perpetual calendar ultra-thin flaunts its technical complexity with all the inherent elegance and distinction of the collection. This model with its timeless design is instantly recognisable: a hexagonal bezel evoking the Maltese cross, a fluted crown, polished and satin-brushed finishes, a translucent lacquered dial with facetted and luminescent gold hour-markers and hands… This watch exudes a sense of total harmony wherever it may find itself.

Its blue lacquered dial with a sunburst satin finish features an aura of relaxed elegance, displaying the hours, minutes, perpetual calendar indications – meaning the day of the week, date, month and leap year by 48-month counter – 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. Achieving such a performance with such a thin movement, comprising 276 components, called for authentic prowess in terms of both construction and miniaturisation.

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.
