Jacob & Co. Astronomia Gravitational Triple Axis Tourbillon Piece Unique

The Jacob & Co. Astronomia Gravitational Triple Axis Tourbillon Piece Unique Ref. AT150.40.AC.SD.A is a one-of-a-kind masterpiece that pushes the boundaries of haute horology. Encased in a 50mm sapphire and 18k rose gold case, this timepiece offers a 360-degree view of its intricate mechanics, protected by a domed sapphire crystal extending over the sides. At its core, the triple-axis gravitational tourbillon rotates on three axes, counteracting the effects of gravity and showcasing constant motion. Surrounding this marvel are three rotating elements: a magnesium globe representing Earth, a diamond-cut moon, and a time display subdial that remains upright thanks to an advanced differential system. Powered by the hand-wound JCAM10 caliber, the movement completes a full rotation every 20 minutes and boasts a 60-hour power reserve. Paired with a blue alligator leather strap and rose gold folding clasp, this unique creation is both a kinetic sculpture and a testament to technical innovation.
