Vacheron Constantin Drops New Les Cabinotiers Model

Vacheron Constantin has once again pushed the boundaries of haute horlogerie with the release of a singularly exclusive creation: the Les Cabinotiers Temporis Duo Grand Complication Openface. This one-of-a-kind wristwatch unites three of watchmaking’s most demanding complications—minute repeater, split-seconds chronograph, and tourbillon regulator—into a single mechanical marvel, powered by the highly sophisticated Calibre 2757 S.

Housed in a 45mm 5N pink gold case, the timepiece showcases a striking open-faced sapphire dial and caseback, providing a clear view into the intricate workings of the 696-component movement. The transparent display not only highlights Vacheron Constantin’stechnical ingenuity but also its dedication to exceptional hand-finishing, with bevelled, polished, and engraved surfaces enhancing the kinetic artistry of the calibre.

The Calibre 2757 S represents a feat of engineering and design. The single push-piece chronograph employs a dual column-wheel mechanism to manage both standard and split-seconds timing functions, accurate to 1/5th of a second. Lightweight materials such as aluminium and silicon have been used to optimise performance, reduce friction, and extend the power reserve to an impressive 50 hours, even with the chronograph running.

A standout feature is the minute repeater’s silent centripetal governor, which ensures the clarity and precision of each chime, devoid of mechanical noise. Meanwhile, the tourbillon—located at 6 o’clock—features a rare spherical hairspring, enhancing isochronism by maintaining a perfectly concentric expansion and contraction of the spring. The Maltese cross-inspired tourbillon cage further reflects the Maison’s heritage.

Design elements also elevate this timepiece into a work of horological art. The open sapphire dial, a mere 0.5 mm thick, is adorned with gold-ringed counters, NAC-treated markers, and olive green aluminium chronograph hands that match the alligator leather strap.

A testament to craftsmanship, the decoration of each component demanded twice as long as the assembly. True to 18th-century traditions, one master watchmaker oversaw the entire creation process from finishing to final adjustment.

With the Temporis Duo Grand Complication Openface, Vacheron Constantin continues its 270-year legacy of technical excellence, artistic mastery, and devotion to the preservation of traditional Swiss watchmaking.
