OVERSEAS SELF-WINDING HIGH JEWELLERY First fully gem-set model for the Overseas 35 mm self-winding

Two new Overseas self-winding 35 mm pieces in 18K white gold and 18K 5N pink gold, fully set with 1,430 brilliant- and baguette-cut diamonds.

Each model is presented with two additional, interchangeable straps in shiny alligator leather and rubber, with an interchangeable diamondset buckle.

The self-winding Manufacture movement, calibre 1088/1 with a 40- hour power reserve displays hours, minutes and central seconds, as well as the date in an aperture Vacheron Constantin opens a new chapter for the Overseas selfwinding 35 mm model, introducing two high-jewellery versions for the first time, in 18K white gold and in 18K 5N pink gold, powered by the Manufacture movement, calibre 1088/1. Originally created in 2023, the 35 mm Overseas case was conceived as a timepiece to suit all discerning wrists in any situation. Its more streamlined dimensions make it intrinsically comfortable to wear, while retaining all of the aesthetic codes and inherent functionality of its larger Overseas counterparts.

The dazzling craft of gem-setting

Vacheron Constantin has been on a quest for excellence in the art of gem-setting since the 19th century, when it added the craft to its repertoire of métiers d’art. At that time, timepieces were not only confined to a waistcoat pocket but were also worn as jewellery and fashion accessories. The new Overseas Self-Winding 35 mm

High Jewellery watch is adorned with a total of 1,430 diamonds (~12.58 cts) and combines two cuts: brilliant and baguette.
The Maltese cross motif on the bezel – a signature of the Overseas collection, inspired by Vacheron Constantin’s emblem – is highlighted by the radiance of 60 invisibly set baguette-cut diamonds (~ 2.28 cts). Invisible setting is particularly challenging for the gem-setter as it creates a seamlessly gem-covered surface on which the stones appear to float above the gold surface with no visible means of support. First, the gem-setter creates a framework of gold rails, only 0.2 mm to 0.4 mm thick, which forms a secure grid structure that remains hidden once the gemstones are slotted into it. After creating the frame, the artisan must cut a tiny V-shaped groove along both sides of each diamond, to match the position and dimensions of the rails with a tolerance of only 0.02 millimetres, thus ensuring that the stones sit flush, with no gaps, overlaps or visible metal. This setting technique is so meticulous that it can take several hours for just one stone.

The serene beauty of the invisibly set baguette stones contrasts with the multifaceted sparkle of brilliant-cut diamonds on the dial and 18K gold bracelet. The dial is elegant and functional, displaying only the essentials of time and date, in order to maximise the visual impact of the snow-set diamond background – comprising 314 brilliant-cut diamonds (~ 1.65 ct). Combining artistry and precision, snow setting is another highly demanding technique, in which the gemsetter covers the entire surface of the gold dial base in diamonds of varying diameter, set in an order that appears to be random. In fact, the placement of every stone must be meticulously judged, to leave an absolute minimum of metal between the stones so that the entire surface refracts and reflects the light, like the effect of the sun on a sparkling field of snowflakes. Against this glittering backdrop, 12 baguettecut diamonds serve as hour markers. The lugs and 18K gold bracelet are also snow-set, with a total of 884 brilliant-cut diamonds (~ 6.95 cts), with each link of the bracelet set separately before being carefully assembled.

One watch, three styles

Introduced to the Overseas collection in 2023, the 35 mm diameter case is designed not only to correspond with a modern aesthetic, but also to be suitable for any situation and comfortably worn by everyone regardless of wrist size. Its versatility is underlined by the easy interchangeability of its diamond-set gold bracelet and two straps that are delivered with the watch: one in white rubber and one in shiny alligator leather. Adding a vivid splash of colour to the otherwise monochrome palette of the watch, the white gold model comes with a brilliant blue alligator-skin strap, while the pink gold model is delivered with a fuchsia-coloured alligator-skin strap. Each is secured with an 18K white gold or 18K 5N pink gold pin buckle to match the case metal; set with 62 brilliant-cut diamonds (~0.33 ct), the buckle may also be interchanged to fit another strap of the owner’s choice. As with all Overseas models, the owner needs no tool to easily and quickly change the bracelet, straps or buckle at will. Echoing the Maltese Cross motif found on the bezel the bracelets are outfitted with the easy-fit system inherent to the Overseas collection since 2016, a hidden micro-adjustment that provides the wearer with flawless comfort.

Vacheron Constantin’s self-winding calibre 1088/1

Calibre 1088/1 sets the pace for the Overseas SelfWinding High Jewellery, driving the hours, minutes, central seconds and date in an aperture. The central seconds is also outfitted with a stop-seconds function, ensuring to-the-second accuracy when setting the time. The 144-component automatic movement operates at a frequency of 4Hz and is equipped with a 40-hour power reserve. Visible through the transparent sapphire crystal case back, the movement is very finely finished and features visible Côtes de Genève decoration and bevelled bridges, as well as the Overseas collection’s emblematic 22K gold rotor adorned with a compass rose.

Vacheron Constantin Overseas Grand Complication Openface

THE FIRST MINUTE REPEATER IN THE OVERSEAS COLLECTION

HAUTE HORLOGERIE PROWESS

The Vacheron Constantin Overseas Grand Complication Openface is the outcome of a long process to meet the challenge of integrating a grand complication mechanism into an elegant case. In addition to a tourbillon and a perpetual calendar, this movement incorporates a minute repeater, a first in the collection. Generally speaking, water resistance is difficult to achieve with minute repeater calibres due to the sliding mechanism in the case-side that activates the repeater. The challenge with this model was to ensure the water-resistance of the Overseas case, while adapting its lines to Calibre 2755 QP. This required a year and a half of research and development and involved a complete redesign of the caseback to create space for the minute repeater mechanism while maintaining the slender curves characteristic of Overseas watches. With a diameter of 44.5 mm and a height of 13.1 mm, the proportions of this new Overseas case deftly balance the collection’s adventurous character with a spirit of elegance.

AN EMBLEMATIC CALIBRE

One of Vacheron Constantin’s emblematic movements, Calibre 2755 QP benefits from developments made for the Tour de l’Île watch presented in 2005 and brings together three major horological complications. With its 602 components contained within a diameter of 33.30 mm, it incorporates a perpetual calendar with date, day, month and leap-year cycle indications. In addition to this calendar mechanism, which requires no correction before 2100 – a non-leap secular year – there is a minute repeater.

To govern the cadence of the repeater mechanism, which strikes the hours, quarters and minutes on demand, the Maison’s watchmakers developed a centripetal regulator, a proprietary device that allows the hammers to be struck at the precise intervals required to obtain the correct musical sequences. Totally silent, this regulator features two centrifugal weights that act as a motor brake on the axis of rotation, smoothing the flow of energy released by the repeater spring.

In keeping with Vacheron Constantin’s attention to detail, particular attention has been paid to the aesthetics of this governing device, which is visible through the sapphire caseback. An arc-shaped bar secures the regulator; crafted in 750/1000 gold its rounded form requires a full day of meticulous hand- polishing. Beneath it, the circular-grained inertia weights are engraved with the initials of Jean-Marc Vacheron, who founded the Maison in 1755.

AN EMBLEMATIC CALIBRE

The same high standards were applied to the finishing of the tourbillon bridges, which involved rounding the convex profile as well as tapering it towards the fixing screws, then hand- polishing each bridge to a perfect shine. Their architecture was also reviewed, particularly on the reverse side, where it has been made more open and visually lighter. This allows full appreciation of the tourbillon’s ballet, which is enhanced by the relatively slow tempo of 18,000 vibrations per hour (2.5 Hz). Commensurate with the complexity of Calibre 2755 QP, the movement finishes also include mirror-polished repeater hammers, bevelled and satin-brushed bridges, circular satin-brushed wheels, and bridges decorated with Côtes de Genève.

A SPORTY AND CONTEMPORARY AESTHETIC

With its grade 5 titanium case and integrated bracelet, the Overseas Grand Complication Openface watch remains true to the spirit of the collection. Its sporty, contemporary character is enhanced by the transparency of the sapphire dial, which reveals the beauty and complexity of the movement. Applied to the transparent sapphire, the 18-carat white gold hour-markers appear to be floating in space, amplifying the airy aesthetic.

To enhance legibility and create a dynamic contrast with the grey and silver tones of the movement components, the circles surrounding each of the time and calendar indications are treated with a blue metallised finish. The surface of each metallised circle is then engraved in white with the various indications – dates, days, months, years and minutes.

Viewed through the sapphire dial the avant-garde spirit of the watch is highlighted by the contrast between the anthracite grey hue of the NAC galvanic treatment on the bridges and the silvery tone of the rhodium-plated wheels. The mix of finishes on the case and bracelet amplifies the contemporary aesthetic with a visually captivating play of light and reflections. On the bezel, sandblasting combines with polishing and satin-brushing – a new signature for titanium-cased models in the Overseas collection. Like the other pieces in the collection, the model’s titanium bracelet, fitted with a comfort system, is interchangeable without tools and two additional straps – one in blue alligator, one in blue rubber – are offered with the watch.
