Device for displaying a succession of indications of a time variable for a timepiece

A device (1) for displaying a succession of indications of a time variable for a timepiece, the display device (1) comprising:

• an indicator which carries the succession of indications of the time variable to be displayed or which points to this succession of indications of the time variable to be displayed, this indicator being arranged to be driven by a horological movement so as to move from an initial position to a final position through a succession of intermediate positions in which the display of the time variable passes from one indication to the next indication at a required frequency;
• a mechanism for positioning the indicator in a reference position;
• and
• an actuating device,
• the mechanism for positioning the indicator in a reference position comprising a wolf-toothed rack (90) which drives, corrects and brings back, into the reference position, the indicator carrying the succession of indications of the time variable to be displayed or pointing to the succession of indications of the time variable to be displayed, the driving and correction of the indicator being carried out by driving the wolf-toothed rack (90) by one tooth, the reverse motion whereof is prevented by a pawl (98), and the positioning of the indicator in a reference position being ensured by actuating the pawl (98), which releases the wolf-toothed rack (90), the latter returning to its rest position under the action of a return spring (92), in which the pawl (98) engages with a tooth (102) provided at the end of this wolf-toothed rack (90).
