Les Cabinotiers minute repeater tourbillon sky chart - Vacheron Constantin
This one-of-a-kind model combines three major complications - minute repeater, tourbillon and sky chart - and is adorned with an invisible setting.

Ably meeting the highest technical, aesthetic and artistic challenges, the one-of-a-kind Vacheron Constantin models created by its Les Cabinotiers department are heirs to the prestigious history of the cabinotiers, these Geneva’s most experienced watchmakers who exercised their talent in workshops bathed in natural light and known as cabinets in the 18th century.

The Les Cabinotiers minute repeater tourbillon sky chart piece follows in the wake of the Celestia Astronomical Grand Complication 3600 and the Symphonia Grande Sonnerie 1860 created by the Les Cabinotiers department in 2017.

Sideral time 

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 guilloché pattern. The pure design and the sparkle of precious stones highlights the tourbillon at 6 o’clock and serves as a reminder that this watch with its minute repeater function belongs firmly within the Fine Watchmaking universe.

This cosmic vision is further enhanced by the sky chart appearing on the case-back. In this depiction of 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.

Calibre 2755

To drive the various functions of this technical watch, Vacheron Constantin’s watchmakers chose to develop a new manual-winding movement specifically dedicated to its

Les Cabinotiers collection. Endowed with a 58-hour power reserve and including 413 components, it is inspired by the Calibre 2755 reserved for the particularly sophisticated models of the Manufacture, notably its exceptionally Grand Complication timepieces.

The watch is fitted with a hand-stitched, black Mississippiensis alligator leather strap with large square scales, saddle-finish. The polished half Maltese cross-shaped 18K white gold folding clasp is set with 12 baguette diamonds (appr. 0.88 ct.)
