At its heart is the new manually wound Calibre 3670, developed over three years. The movement offers a world-first dual mode of time display, continuous or “on-demand” and features retrograde hour and minute hands in the form of a sculpted human figure. The astronomical display includes a three-dimensional moon phase and a celestial vault fixed to the night sky exactly as it appeared in Geneva on 17 September 1755, the founding date of the Maison, while the reverse dial charts the constellations in real time with extraordinary accuracy. Showcasing a 5 Hz high-precision movement with a six-day power reserve and finished to the demanding standards of the Poinçon de Genève, the Métiers d’Art – Tribute to the Quest of Time fuses four patented innovations with the Maison’s most intricate decorative crafts.
