Timepiece wheel set with a unidirectional wheel rotating in only one direction in cooperation with a ratchet wheel, which is movable inside a ratchet wheel chamber, comprising a click that rotates integrally with this wheel, which forms a one-piece component comprising at least one spring-arm, at the end of which, on a first side, a beak cooperates directly with the toothing of a ratchet wheel in an operating position in which this spring-arm is free, and on a second side, a first hook can cooperate with a second hook of complementary shape, comprised in this one-piece click, in a rest position in which this spring-arm is in an extended position, the elasticity thereof allowing this first hook to be hooked or unhooked with respect to this second hook by the action of an operator, by maximum elongation of this spring-arm and/or by the tilting of this end.

A stop pawl for a horological movement, including a body provided on the periphery with a lug for latching with the toothing of a ratchet; a hub intended to cooperate freely in rotation with a fixed rod according to an angular displacement between an active position meshing the lug with the toothing of the ratchet and an inactive position, via intermediate positions; wherein the pawl includes at least one device for returning the pawl during its angular displacement, from the inactive position to the active position; and wherein the return device and the body are made in one piece. A horological movement and timepiece can include such a pawl.

A disengageable winding device (1) for a barrel (2) provided with a spring, comprising a ratchet (3) mounted on a winding arbor such that it is rigidly connected thereto, the winding arbor being an arbor for winding the barrel (2), the rotation of which winds up the barrel (2), and a winding gear train (40) meshing with the ratchet (3), the rotation of the winding gear train (40) driving the rotation of the ratchet (3) and that of the winding arbor.

The mechanical timepiece movement with power reserve indication comprises at least one barrel system connected to a winding wheel of a differential gear and an unwinding wheel of the differential gear. An intermediate wheel of the differential gear is connected to a cam wheel set to drive it in rotation via a reducing stage. A rack, which acts on a power reserve indicator, is in contact with the cam wheel set. When the power reserve is at zero, a locking part of the rack comes into contact with a locking member to lock the movement at an unwinding output of the barrel system or in contact with the unwinding wheel of the differential gear.
