This year’s edition of the Grand Prix d’Horlogerie de Genève has awarded the Mechanical Exception Watch Prize to Vacheron Constantin’s Les Cabinotiers Celestia Astronomical Grand Complication 3600. Five years of development and the involvement of a dedicated master-watchmaker were required to create this exceptional model that pushes the limits of innovation and excellence.
This tourbillon watch with a three-week power reserve features 23 essentially astronomical complications appearing on the front and back dials, providing time read-off in three modes – civil, solar and sidereal – each driven by its own gear train. This model acknowledged by the industry, collectors and connoisseurs for its engineering and its technical sophistication houses a fully integrated 514-part calibre measuring a mere 8.7 mm thick.
Pursuing the path traced by Reference 57260 – the world’s most complicated watch equipped with 57 complications – which won the Special Jury Prize in 2015, the Celestia Astronomical Grand Complication 3600 is a bright new star in the Fine Watchmaking firmament.
