Overview
A planetary system on a vertical movement
The Jacob & Co. Astronomia Tourbillon, reference AT100.31.AC.SD.A, in an 18-carat black gold case, 50 mm across and 25 mm high. Its titanium dial sits over a base of 18-carat black gold and aventurine, on a black alligator strap with an 18-carat black gold deployant buckle.
The case, caseback and base dial are 18-carat black gold, and the hands are blued.
Astronomia Tourbillon is Jacob & Co.’s wrist-sized model of a planetary system. A vertical platform with four arms rises from an aventurine base and makes a full revolution around the central axis in 10 minutes. The complications take the form of planetary bodies: a tourbillon, a diamond moon, an Earth globe and a rotating dial.
Hand-wound calibre JCAM10 has 365 components, 42 jewels and a 60-hour power reserve. Jacob & Co. describes it as a three-dimensional movement built on a central vertical axis. The hour and minute dial turns on a patented differential, counter-rotating against the platform at matching speed, so it stays upright and readable. This version is limited to 18 pieces.
