Abstract (en)

[origin: EP0548659A1] The invention relates to a timepiece. This timepiece comprises: - a clockwork movement (1) including a motive or connecting pinion (2), - an internally toothed crown (6) associated with a first display device, such as a calendar display, and with a jumper spring (8), - a driving runner (10) including a driving wheel (12) controlled by the motive pinion (2) and transmitting to the crown (6), by way of a prominent tooth (14), a motive couple received from the motive pinion (2), this runner (10) moreover including a hub (16) which is mounted free in rotation with respect to the movement and which supports the driving wheel (12) elastically by way of an elastic arm (22), this timepiece being characterized in that the elastic arm (22) which supports the driving wheel (12) has essentially a C shape enfolding the hub (16), whilst the driving wheel (12) meshes directly with the motive pinion (2). The invention applies to a timepiece of the mechanical or electromechanical type. <IMAGE>
