Abstract (en)
[origin: CN104714394A] In the control method for an analogue display device fitted to a timepiece movement, the motor (16) is used both for driving a first indicator (4) of a time parameter and a second periodically driven indicator (6). To this end, the motor is controlled such that, when the first indicator is in an operating mode and the second indicator is arranged to remain substantially immobile, said first indicator is driven in rotation by the motor alternately: in a forward direction, to display the time parameter, during a first period in which a periodic actuation wheel set (36) is simultaneously driven in positions of its area of non-actuation (Beta 1 and Beta 2), and in a backward direction, in accelerated mode, during a second period following the first period, before the periodic actuation wheel set is driven in a position of its area of actuation (Alpha 1 and Alpha 2).
