A power reserve display mechanism includes a differential (22) having: a first input (22a) connected to a ratchet (16) of a barrel (24) and to an oscillating mass automatic winding system, a second input (22b) connected to the drum of a barrel (24), an output (22c) connected to a display system. The display system includes at least one disc (40) provided with digits for displaying numbers between a minimum number and a maximum number. Moreover, the disc is connected to the output (22c) of the differential (22) via a reduction train (26), arranged such that the display system displays the minimum number when the barrel is empty and the maximum number when the barrel is maximally loaded. The reduction train and the automatic winding system are arranged such that the disc advances by one pitch each time the oscillating mass performs on revolution. |
