Jacob & Co.’s Astronomical Gravitational Tri-Axis Tourbillon in Black Gold, a simplified replica of the celestial body located on the wrist. Novelty leaves an indelible impression. The 3D Calibre JCAM10 pushes the limits of technical possibilities, allowing this watch to present a stunning choreography of axis-based indicators.
The central shaft and the four hands and their modules complete one revolution in 20 minutes. The tourbillon combines a 5-minute rotation around the vertical axis with a 60-second horizontal rotation. On the other side there is a sub-dial with hour and minute indications that are always visible to the owner of the watch. Therefore, the watch face is not overloaded with functions. On the cross axes on either side are a lacquered Earth and a diamond moon. The diamond surface has 288 facets, reflecting all light in all directions, illuminating the starry sky through the tourbillon and free axis. The end result is an unforgettable light show that won’t be repeated twice. Jacob & Co. Astronomia
