Vacheron Constantin expands its Overseas line with a striking new tourbillon rendered in titanium and set off by a rich, deep-red dial. The choice of titanium underscores the collection’s dual personality—sporty yet refined—offering exceptional strength with featherweight comfort. Hallmark of Geneva certified and powered by the ultra-thin calibre 2160 (just 5.65 mm thick), the watch houses a tourbillon regulator while remaining supremely wearable.

Titanium proves an ideal material for this purpose: about 30% stronger than steel yet roughly half its weight, it conveys both resilience and agility. Vacheron Constantin first introduced titanium into the Overseas family in 2009, later using it for the Everest models developed with explorer Cory Richards, and has since pushed the metal’s potential with fully titanium tourbillon executions. This latest iteration follows earlier titanium tourbillon references and arrives with a new, dramatic dial color.

The deep-red dial is finished with a sunburst satin-brushed surface and a lacquered flange, treatments that emphasize the watch’s horological pedigree and draw the eye toward the tourbillon aperture. The grade 5 titanium case receives the same careful aesthetic treatment: polished bevels on the bracelet links, vertical satin brushing on the case face, and a bezel whose profile recalls the Maltese cross, combining circular satin brushing with a sandblasted ring. The result is an ultra-thin silhouette—just 10.39 mm from crystal to caseback—that reads both technical and elegant.

Designed for versatility, the model is offered with an integrated titanium bracelet that closes with a triple-blade folding clasp and a comfort-adjustment mechanism allowing up to 4 mm of additional wrist circumference. For a change of mood, two quick-change rubber straps in deep red and white are supplied, each fitted with an interchangeable grade 5 titanium folding clasp that can be swapped without tools.

At the heart of the watch sits the automatic tourbillon calibre 2160, a movement with a 31 mm diameter and a profile of only 5.65 mm. Its ultra-thin architecture incorporates a tourbillon cage and a peripheral oscillating weight—featuring a guilloché 916/1000 gold segment—that winds bidirectionally and delivers an 80-hour power reserve. By placing the winding mass at the periphery and integrating it with the bridges, the movement achieves a reduced overall thickness while offering an unobstructed view of its mechanics.

The openworked tourbillon cage uses a peripheral drive that removes the need for a central pinion, optimizing energy transfer from the mainspring barrel to the balance wheel. This technical choice enhances efficiency and contributes to the movement’s slender profile.

Finishing is executed to the highest standards, with 188 components that play with light across the movement. The mainplate is circular-grained, the bridges bear hand-beveled edges and Côtes de Genève, the wheels are grained, and the screws are chamfered and polished. Even the tourbillon shank is delicately supported—small details that collectively attest to meticulous craftsmanship.

But let’s dig even deeper with this new creation, and find out what Mr. CHRISTIAN SELMONI, Style and Heritage Director at Vacheron Constantin, has to say about the new Overseas Tourbillon…

Has titanium become an essential material in the Overseas collection?

Vacheron Constantin’s attraction to titanium dates back some fifteen years. Initially, this material was preferred for the case components, helping to reinforce the collection’s sporty and robust character. The last four years have been marked by the emergence of timepieces made entirely of titanium with integrated bracelets, which have established themselves as a preferred alternative to the steel watches in the Overseas collection. Titanium is particularly prized for its inherent qualities: hypoallergenic, lightweight, and possessing high mechanical and corrosion resistance. In short, it is a material perfectly suited to the Overseas spirit, a watch designed to withstand the rigors of travel.

Is a tourbillon model, known to be fragile, compatible with the concept of a sports watch?

Since the invention of the tourbillon in the early 19th century, watchmaking technology has undergone major advancements. These advancements concern not only materials science but also crucial elements such as shock-absorbing systems that protect the regulating organs. These two elements combined now make it possible to create tourbillon watches suited to an active lifestyle with a sporty elegance unthinkable just a few decades ago. Add to that a case made entirely of titanium, and you have a slim, lightweight, and robust watch with exemplary precision thanks to its tourbillon regulator, which compensates for the effects of gravity.

Why this deep red color?

The Overseas watches form a collection that lends itself beautifully to new color explorations. This became clear when the Maison introduced a pink hue on certain women’s models and, more recently, intense green or gold dial colors. From there, it was interesting to continue by introducing new variations that bring a touch of originality. The deep red color, elegant and intense, fits perfectly into this vision.
