Device () for selecting a clock function from a rewinding function and m correction functions, m&#x3e;1, comprising a control member (), notably a staff, able to select the rewind function by movement of the control member in a first direction and to select sequentially one function from m correction functions by movement of the control member in a second direction.

Mechanism for rewinding and/or correcting at least one clock function and device for selecting a clock function

At least some of the uniformly distributed teeth of one of the antibacklash partner toothed wheel units, of this backlash-compensating gear train for a horological mechanism, have elastic parts (D) that are flexible in the direction of the respective thicknesses of the teeth. Some of the teeth are capable of temporarily transmitting a torque considerably greater than the normal drive torque. Two adjacent teeth (D, D) capable of temporarily transmitting a torque considerably greater than the normal drive torque each comprise one flank (D, D) integral with a more rigid part (D), and one flank (D, D) integral with a more flexible part (D, D), the two more rigid parts (D) of the two teeth (D, D) being adjacent.

This timekeeper comprises a first timer (), means () for connecting it selectively to the train of the timekeeper (T), a second timer (), a synchronous coupling between the first () and second () timers, and fly-back means () for said timers (). An auxiliary motive source (') is in a driving relationship with the second timer () and a one-way coupling () is situated between the first () and second () timers to regulate the speed of movement of the latter at a predetermined ratio with the speed of movement of the first timer () while allowing one-way relative movement of the first timer () relative to the second () when the latter is in the stop position and one-way relative movement in the opposite sense of the second timer () when the first timer () is in the stop position.
