Vacheron Constantin Les Cabinotiers Temporis Duo Grand Complication Openface

In the world of watchmaking, whenever VACHERON CONSTANTIN unveils a new creation from its Les Cabinotiers collection, it’s as if a thunderous symphony breaks through the silence. The newly launched 2025 Les Cabinotiers Temporis Duo Grand Complication Openface is precisely such a resonant high note — a masterpiece that instantly captivates the eye with its overwhelming presence.

Three Grand Complications in One

The new Les Cabinotiers timepiece brings together three major complications — minute repeater, split-seconds chronograph, and tourbillon — showcasing Vacheron Constantin’s relentless pursuit of technical limits while continuing its 270-year horological heritage, redefining the standards of modern haute horlogerie.

What makes this watch particularly special is not just the inclusion of these three iconic complications, but how harmoniously and elegantly they are integrated. Encased within a 45mm rose gold case, these functions are executed with precision and artistry, achieving a perfect balance between technical prowess and aesthetic finesse — every visible aspect is mesmerizing.

Refined Movement and Artistic Openworking

The heart of the watch is the upgraded 2757 S movement, evolved from the 2757 caliber introduced in 2022. It retains its complex architecture while enhancing performance and integrating openworked aesthetics for greater refinement in both technique and artistry.

This timepiece does not intend to hide its complexity. Instead, it proudly reveals its mechanical soul through the transparent sapphire crystal dial and caseback. The entire movement is laid bare, almost without concealment. The ultra-thin 0.5mm transparent sapphire dial is itself a marvel, treated with alternating polished and satin finishes. It is accented with a 5N rose gold ring and gray NAC-coated hour markers, giving the watch a distinct and layered sense of quality.

Design Details and Chronograph Harmony

The deep green chronograph hands echo the green alligator leather strap, paired with a bold 45mm rose gold case — together they form a dynamic tension between modernity and classic elegance. From overall proportions to the interplay of details, everything demonstrates Vacheron Constantin’s mastery of aesthetic logic.

At 6 o’clock, the tourbillon cage is prominently displayed, inspired by the brand’s iconic Maltese cross. It rotates once per minute, with a small seconds hand mounted on its axis. What makes this tourbillon even more remarkable is its use of a rare spherical balance spring — allowing it to expand and contract concentrically, thus improving the isochronism of the balance wheel and enhancing the stability of timekeeping.

The time display is positioned on a sub-dial at 9 o’clock, showing hours and minutes, while the 30-minute chronograph counter at 1–2 o’clock helps indicate the split-seconds timing result. In addition, the dial offers a broad view of the intricate openworked movement, letting one fully appreciate the formidable complexity behind this watch.

Precision Engineering and Material Innovation

The Les Cabinotiers Dual-Time Grand Complication Openworked watch is powered by the hand-wound caliber 2757 S — a micro-architectural marvel composed of 696 components. It has a diameter of 33.3mm and an astonishingly thin profile of only 10.4mm — an extraordinary feat considering it houses three major complications.

Vacheron Constantin’s engineers and watchmakers have cleverly applied various modern materials to overcome technical hurdles. For example, titanium and nickel-phosphorus electroformed gears are used in the chronograph train to ensure smoother transmission; aluminum is used for the chronograph seconds hand to reduce weight; and silicon components — which require no lubrication — are employed in the split-seconds clamps and isolators to reduce friction and wear.

These innovations not only lighten the movement’s load but also allow the watch to maintain a 50-hour power reserve while operating complex functions. The 18,000vph frequency ensures precise 1/5-second chronograph timing, and the dual-column wheel mechanism provides both crisp and reliable operation.

Finishing, Tradition, and the Spirit of the Cabinotiers

The caseback reveals the beauty of hand-finished craftsmanship — blackened bridges with sandblasted and mirror-polished finishes form striking contrasts. The minute repeater’s governor even bears the hand-engraved initials "JMV" of the brand’s founder, embodying artisanal finesse and a spirit of heritage.

Minute repeaters have always been the most emotionally resonant complication in haute horlogerie. The repeater in this Les Cabinotiers creation features a Flying Strike Governor — a unique mechanism that uses centrifugal and centripetal force to regulate the chiming rhythm. This ensures that the chime is pure and serene, without any ticking noises — only the clear, crisp sound of metal hammers striking gongs, like a miniature concert crafted for each chime, released with a push of the slide.

If assembly is the process by which a watch is born, then finishing is where the soul of the craft is instilled. The finishing time for the 2757 S movement is twice as long as the assembly time — a fact that redefines our understanding of watchmaking. Every bevel, every polish, every brushed stripe on the bridges is done by hand. Even on the repeater governor, one can find the founder Jean-Marc Vacheron’s initials “JMV” meticulously hand-engraved — a subtle testament to the brand’s history and the artisan’s spirit.

The Watchmaker’s Masterpiece

Staying true to the “Les Cabinotiers” tradition, the watch is completed entirely by a single master watchmaker — from finishing, assembly, to final adjustment — showcasing the ultimate in artisanal value and Vacheron Constantin’s unwavering commitment to high watchmaking.

What is perhaps most awe-inspiring and admirable is that this entire Les Cabinotiers Dual-Time Grand Complication Openworked timepiece is the work of a single master watchmaker, who was responsible for every stage — from hand-finishing, assembly, regulation to casing. This is not just a continuation of traditional craftsmanship, but the truest manifestation of the Les Cabinotiers spirit upheld by Vacheron Constantin.

Whenever one peers through the openworked dial to observe the movement in action — the gears turning, the balance wheel oscillating, the hammers striking — it’s as if the watch is whispering to its wearer: “This is the art of time.” Within the 270-year legacy of Vacheron Constantin, this piece marks yet another breathtaking achievement, prompting us to reflect anew — how far can the limits of watchmaking truly go?
