Abstract (en)
[origin: US4676659A] A time indicator for a timepiece is driven by an arrangement comprising a driving train and a transmission assembly. The driving train includes a finger adapted to drive a pinion of small diameter and a circular flange adapted to block a pinion of large diameter. The small and large diameter pinions are coaxial, fixed to one another and compose the transmission assembly. In this manner the time interval in passing from one indication to another is diminished while avoiding the butting phenomenon of teeth resting on the circular flange.
