1. A method of determining a motion for a display member of a timepiece, the method comprising:

  • rotating a crown of the timepiece;

    establishing a model for calculating at least one simulated mechanical force and/or torque value from values measured from the rotating crown by a sensor;

    obtaining a physical magnitude from the rotating of the crown;

    inputting the physical magnitude, measured values, and at least one simulated force and/or torque into a Newtonian equation of motion;

    solving the Newtonian equation to calculate a simulated speed for said display member; and

    moving the display member at the simulated speed,wherein the display member is a movable mechanical component that is viewable on the timepiece.
