Abstract: The invention relates to a timepiece transmission device (100), particularly for a timepiece mechanism (110) and specifically for an automaton chain (5) of a timepiece movement (120). Said timepiece transmission device includes: a first device (1), particularly a first freewheel device (1), for unidirectionally connecting a first portion (1a) to a second portion (1b); and a brake (2) arranged so as to brake, particularly by means of friction, the first portion in relation to the second portion.
