Vacheron Constantin Les Cabinotiers Minute Repeater Tourbillon Sky Chart

Incorporating three major horological complications – minute repeater, tourbillon and sky chart – this one-of-a-kind timepiece was created by the watchmakers of the dedicated Les Cabinotiers department of Vacheron Constantin.

Following the footsteps of the Celestia Astronomical Grand Complication 3600 and the Symphonia Grande Sonnerie 1860 created by the Vacheron Constantin Les Cabinotiers department in 2017, this high technical complication watch successfully associates three high horology complications: the minute repeater function, a tourbillon and a depiction of the starry heavens.

Showcasing the technical art of horology along with the aesthetic values of the Manufacture, this new creation echoes the consummate skills that have given rise to the Vacheron Constantin most emblematic and technical models.

The white gold case of Les Cabinotiers minute repeater tourbillon sky chart features a powerful aesthetic contrast: the bezel and lugs set with baguette-cut diamonds illuminate a pure black dial punctuated by baguette-cut diamond hour-markers and accentuated by a central guilloche pattern. This subtle contrast between the pure design and the sparkle of precious stones highlights the tourbillon at 6 o’clock.

The sky chart appearing on the case-back depicts the night sky above Geneva, the Milky Way, constellations and stars shine brightly as if viewed through a telescope. The celestial tableau performs one full spin on its axis in 23 hours and 56 minutes, corresponding to sidereal time.

The concave dial shape accentuates the depth effect. In keeping with horological standards, an ellipse drawn on the sapphire crystal emphasises the exact position of the constellations when the wearer consults the watch. Finally, this fascinating sight is complemented by indications of sidereal time, months and cardinal points.

The new manual-winding high complication movement specifically dedicated to the Les Cabinotiers collection is endowed with a 58-hour power reserve.
