High Watchmaking Boundaries

Innovation at the heart
of watchmaking excellence


Technical Exploration

Pushing the limits
of mechanical innovation

Pushing limits in watchmaking is not merely about adding functions, it is about redefining architecture. In 2026, Vacheron Constantin explores complexity through three dimensions: finesse, transparency and absolute mechanical scale.

The exploration of finesse

New Utra-thin manufacture
calibre 2550

With the introduction of the new self-winding ultra-thin movement Calibre 2550, Vacheron Constantin redefines the balance between slenderness and performance. This self-winding movement achieves an impressive 80-hour power reserve within just 2.4 millimeters thickness, an achievement where refinement and robustness coexist in perfect equilibrium.

Ultra-Thin self-winding movement

Precision at the
micron level

Seven years of research and development, aimed at enhancing performance, led to the design of an innovative architecture combining a micro-rotor, a suspended double barrel and a compact single-level gear train. Calibre 2550 makes its debut in a new watch crafted in 950 platinum and measuring 39.5 mm in diameter: the Overseas Self-Winding Ultra-Thin.

Calibre 2755 is one of Vacheron Constantin’s emblematic movements. Designed to accommodate the noblest complications of Haute Horlogerie, it integrates a tourbillon regulator and a minute repeater mechanism. True to its spirit of innovation, the Maison now presents a skeletonised version of this movement, an achievement that required one full year of development.

An architecture of Contrast

Light, depth and mastery

The skeletonised Calibre 2755 TMR SQ is enhanced by nine meticulous finishing that underscores its complexity. Compared to a traditional calibre, this stage requires four times more time due to the minute size of the movement’s 471 components, housed within a thickness of just 6.1 mm.

To accentuate the depth effect, components are distinguished by their tones. In addition to brass and steel parts, anthracite-treated components further enhance contrast.


The summit of complexity

At the edge of possibility

Where mechanical knowledge becomes monumental


Time in its grandest form

La Quête du Temps

Created as a monumental astronomical automaton, La Quête du Temps extends the exploration of complexity beyond the wrist. Uniting thousands of components, musical choreography and Métiers d’Art, it transforms mechanical mastery into a theatrical expression of time itself.

A Historic Milestone

Reference 57260

With 57 complications and eight years of development, the Reference 57260 marked a defining moment in contemporary watchmaking. Introducing unprecedented calendar systems and a new chronograph architecture, it demonstrated that complexity, when mastered, becomes a coherent mechanical universe.

Beyond the Frontier

The Berkley Grand Complication

Surpassing its predecessor with 63 complications, The Berkley Grand Complication integrates astronomical indications and the first perpetual Chinese calendar ever realised mechanically. More than a record, it embodies intellectual endurance and the relentless pursuit of horological knowledge.
