ABSTRACT:
In the movement for an electronic watch with analogue display, hand-carrying arbors 20, 22 have pinions 20a, 22a of very small diameter, rather than wheels. The cell 10 has a diameter which is substantially equal to the radius of the movement plate 2, since the cell extends from the periphery of the movement up to the pinions 20a, 22a. The wheels 28, 30, 34, 40, 42 which drivably connect the motor 8 to the pinions 20a, 22a are arranged in such a manner that there is no overlapping between the cell 10 and the wheels. This makes possible a movement which is both of small diameter and thin.
