The new Vacheron Constantin Les Cabinotiers Minute Repeater Tourbillon Sky Chart is one-of-a-kind model combines three major complications, minute repeater, tourbillon and sky chart and is adorned with an invisible setting. The Minute Repeater Tourbillon Sky chart is exceptional in every respect, combining three major complications housed in a white gold case set with 112 baguette-cut diamonds.
This signature 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.
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.
The 413-part movement is based on the hand-wound calibre 2755 beating at 18,000 vibrations per hour and with 58 hours of power reserve. It is regulated by a one-minute tourbillon and integrates a minute repeater. Turning the watch over, the sky chart, which appears on the case-back, depicts the night sky above Geneva, the Milky Way, constellations and stars.
The Milky Way, constellations and stars perform one full rotation in 23 hours and 56 minutes, corresponding to the sidereal time. 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 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.
