Abstract:
1. An inverter device, intended to equip a timepiece movement, including first and second toothed wheels intended to be driven simultaneously in opposite rotation directions by a mechanism of the timepiece movement, said first and second wheels both being coaxial with an output toothed member, intended to be kinematically connected to a pivoting member of the timepiece movement, and are mechanically connected to said output member by first and second unidirectional transmission members, respectively, adapted to transmit to said output member rotation of one wheel or the other in a single predefined rotation direction and to prevent the transmission of rotation of said output member, in said predefined rotation direction, to one or the other of said wheels, wherein each of said unidirectional transmission members includes two teeth that are substantially diametrically opposite and have asymmetrical shapes, and is mechanically connected to said output member in such a manner as to be constrained to rotate therewith whilst being able to be moved between first and second extreme positions in a radial direction with reference to said output member, wherein each of said first and second wheels includes a plate, having a first radius R
