Jacob & Co.’s Astronomia Revolution makes an entire movement orbit each minute

The Astronomia Revolution accelerates Jacob & Co.’s kinetic concept until the movement platform makes one complete turn each minute. Its arms carry the time display, a double-axis tourbillon and a rotating ruby pointer. Eighteen polished gold mirrors beneath the mechanism amplify the changing views.

The hand-wound JCAM48B uses twin barrels and a high-frequency constant-force mechanism to manage that moving structure. It provides a 36-hour reserve inside a 47mm case that reaches 27mm in height. Introduced in March 2023, the edition comprised eighteen watches across three gold treatments. The photographs show the rose-gold execution, with its red suspended time display.
