The Grand Prix d’Horlogerie de Genève has announced it has awarded the Mechanical Exception Watch Prize to Vacheron Constantin’s Les Cabinotiers Celestia Astronomical Grand Complication 3600

An exceptional timepiece, 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.

The watch has been in five years of development, expertly crafted by a dedicated watchmaker to push the limits of innovation and excellence. 

Collectors and connoisseurs have praised this watch for its engineering and its technical sophistication. It features a fully integrated 514-part calibre measuring a mere 8.7 mm thick.

In his acceptance speech, Louis Ferla, CEO Vacheron Constantin, said, “It is truly an honour for a Maison of connoisseurs such as Vacheron Constantin to win this prize for excellence, awarded by a jury also composed of recognised experts and connoisseurs. The Celestia is a model perfectly reflecting our DNA: watchmaking expertise and a profoundly human adventure perpetuated since 1755, along with a spirit of innovation and a consistently forward-driven approach that enables us to continually push technical boundaries.”
