Abstract
A pawl system () for a wheel () of a drivetrain for winding a horology barrel (), including (i) a pawl () having at least one tooth () intended to collaborate with a toothset () of the wheel (); and (ii) an element () for activating and deactivating the pawl, which is arranged so that, when it is in a first configuration, the at least one tooth () of the pawl collaborates with the toothset () directly or indirectly, notably under the effect of a return force returning the at least one tooth () of the pawl against the toothset (), and, when the activation and deactivation element is in a second configuration, the at least one tooth () of the pawl does not collaborate with the toothset () or a return force returning the at least one tooth () of the pawl against the toothset () is reduced.
