The Fine Watchmaking firmament welcomes a bright new star: the unique twin-dial
Celestia Astronomical Grand Complication 3600 combines astronomy and the watchmaking art in a celestial white gold composition. Twenty-three essentially astronomical complications appear on the front and back dials of the watch, providing a reading of time in three modes – civil, solar and sidereal – each driven by its own gear train. Embodying the height of technical sophistication, its new fully integrated 514-part caliber measures a mere 8.7 mm thick, while six barrels guarantee three full weeks of autonomy.
Pursuing the path traced by the majestic Reference 57260 – the world’s most complicated watch equipped with 57 complications created for the 260th anniversary of the Manufacture – Vacheron Constantin presented Les Cabinotiers Celestia Astronomical Grand Complication 3600. Featuring an all-new construction, this mechanical masterpiece follows in the eminent wake of a unique creation representing a milestone in the history of mechanical horology. Five years of development starting from a blank page, a dedicated master-watchmaker, along with two years of design, have given life to the one-of-a-kind Les Cabinotiers Celestia Astronomical Grand Complication 3600, displaying 23 complications on its twin dials. This Haute Horlogerie ‘heavenly phenomenon’ is one of the most complex ever made and heir to a proud lineage of astronomical timepieces. Astronomy, the study of celestial objects, is closely bound up with horology. The former seeks to explain the origins, evolution and properties of heavenly bodies. The latter strives to capture and mechanically express the course of time and its perpetual dance with the stars – a challenge successfully met in this watch providing a combined display of civil, solar and sidereal times by means of three separate gear trains.
