The Sky Watcher tourbillon mechanism features a unique design with three distinct axes of rotation: one around the vertical axis of the clock, another around the horizontal axis, and a third relative to the central axis of the inner sphere. The clock is powered by a mainspring, which stores potential energy, and this energy is gradually released in a controlled manner to drive the movement.
