  • the second member is balanced with a counterweight, which cancels out unbalance.
  • the components of the automaton are therefore not sensitive to the spatial positions of the timepiece, in particular when it is a wristwatch.
  • it is not necessary to use a return spring which makes it possible to reduce the torque required for the transmission, and to have a more constant torque. As this is an oscillating movement, the only torque required is due to the acceleration of the components and their inertia with respect to their axis of rotation.
