Vacheron Constantin Les Cabinotiers Celestia Astronomical Grand Complication

About this reference

The Vacheron Constantin Les Cabinotiers Celestia Astronomical Grand Complication 3600, reference 9700C/000G-B184, was introduced in 2017 as a unique piece following five years of development. This 18k white gold timepiece is valued for the manual-wind caliber 3600, an integrated movement featuring 23 complications across two dials, including civil, solar, and sidereal time displays. The movement utilizes six barrels to achieve a three-week power reserve while maintaining a thickness of 8.7mm. Collectors prioritize this reference for its technical complexity, as it incorporates a mareoscope, a transparent sky chart, and a perpetual calendar. Because it was produced as a single-piece edition, it rarely appears on the secondary market; however, its original retail price was approximately $1,000,000, and current valuations remain in the high-six to low-seven-figure range. This specific reference won the Mechanical Exception Watch Prize at the 2017 Grand Prix d’Horlogerie de Genève.
