“La Musique du Temps®” Les Cabinotiers Minute repeater ultra-thin

The unique Les Cabinotiers ultra-thin minute repeater models, featuring 41 and 39 mm diameters, beat to the rhythm set by the 1731 calibre, an ultra-thin movement with meticulously developed acoustics.

Their pure, refined style is accentuated by Grand Feu enamel dials adorned with precious stone hour-markers. The small model is also graced with a row of brilliant-cut diamonds on its lugs and bezel.

The history of the 1731 calibre

The main characteristic of the 1731 calibre (thus named in a nod to Jean-Marc Vacheron’s birth year) is its extreme thinness for a minute repeater movement. At just 3.90 mm, it is only slightly thicker than its predecessor – the 1755 calibre dating from 1992 – because of its impressive 65-hour power reserve. It took four years to solve this most complex equation: to create a minute repeater movement, combining slimness, a pure sound, pleasing aesthetics, reliability and robustness.

Moreover, the technical feats are not confined to the challenge of extreme thinness, since the 1731 calibre is equipped with one of the most ingenious devices developed in 2007 for the 2755 movement – another member of this exclusive family of minute repeater calibres – a flying strike governor that is entirely silent, unlike conventional lever-type governors, and is tasked with regulating the rate at which hammers strike the gongs.

Acoustics, the real raison d’être of a minute repeater, was the focus of attention. To ensure the sound is crystal clear and perfectly harmonious, several different technical choices had to be made. The gongs are thus not only connected to the case middle so as to amplify the sound, but also superimposed, rather than aligned side by side.

The two pink gold cases are designed to form a single entity with the movement, in a composition that incorporates such subtle parameters as the circulation of air between the mechanism and the case in order to ensure optimal note propagation.

The case has also been seamlessly constructed so that the elements can interact metal to metal and thus increase the amplitude of the sound.

A pair of aesthetes

Both Cabinotiers Minute repeater ultra-thin – The dance of stones models are presented in 18K 5N pink gold cases, respectively measuring 41 mm and 39 mm in diameter.

The latter is the first ladies’ minute repeater model offered by the Maison in this size. Its bezel is adorned with brilliant-cut diamonds, which also sparkle on the lugs, as well as on the crown set with a cabochon.

Both versions feature a Grand Feu enamel dial, one of the most demanding enamelling techniques, whose eggshell white colour makes a perfect match with the classicism of the models.

The 18-carat gold dauphine-type hands complete this aesthetic harmony, punctuated by hour-markers in ruby.

A sonic print certified by Abbey Road Studios

Sound and music have always played a role in the Maison’s partnerships, the latest of which is with Abbey Road Studios, a name closely associated with iconic artists such as The Beatles, Adele and Oasis.

In collaboration with the studios, Vacheron Constantin launched its Fiftysix® collection, backed by the “One of not Many” campaign.

The partnership also has a role to play for “La Musique du Temps®”, as Vacheron Constantin entrusts Abbey Road Studios with recording the unique sound of each model.

“Above and beyond extremely similar values, Abbey Road Studios and Vacheron Constantin work closely together on creative collaborations involving both content creation and sharing expertise. Entrusting the production of the sound prints of our pieces to an internationally recognised expert in the recording world is an integral part of our collaborative endeavours,” explains Laurent Perves, CMO Vacheron Constantin.

For the first time, the repeater watches from the “La Musique du Temps®” range have a unique sound imprint, recorded and certified by Abbey Road Studios.

“The opportunity to capture the sonic identity of these incredible timepieces is a privilege,” explains Jeremy Huffelmann, Head of Partnerships at Abbey Road Studios.

“These recordings perfectly encapsulate the shared values of craftsmanship, expertise and excellence that define our collaboration, whilst forever preserving the personality of these singular timepieces.”
