Abstract: There is provided a device (100) for maintaining or limiting the shake, in at least one direction, of a timepiece component (30) The device includes a stationary structure (20) arranged to abuttingly receive at least one surface of the component (30), and a rotary bolt (10), cooperating with the stationary structure (20). The rotary bolt (10) is rotatable about an axial direction (A) between a first angular position, referred to as the unlocking position, allowing the component (30) freedom of movement and a second angular position, referred to as the locking position, limiting the travel of the component (30) relative to the stationary structure (20) in the at least one direction, and characterised in that the second angular position, referred to as the locking position, of the rotary bolt (10) is secured by a resilient return (3).

Abstract: A horological movement provided with an indicator and includes a mechanism for driving this indicator in jumps, the mechanism including a wheel platform, a rigid part defining a driving finger, and a spring having a first end attached to the wheel platform for rotation therewith and a second end attached to the rigid part for rotation therewith. The mechanism is arranged so that the spring contracts when this spring is loaded to generate a jump by the indicator. An angular displacement of the driving finger relative to the wheel platform is then limited, when the spring is contracted, by an angular stop attached to the wheel platform for rotation therewith. The indicator and the mechanism are arranged so that a jump by the indicator cannot occur, in normal operation, before the angular displacement is stopped by the angular stop, after a loading of the spring preceding this jump, and thus corresponds to a predetermined angular distance (?).

Abstract: A method and device for coupling a rigid element with a spring when assembling or mounting a horological device includes the steps of rigidly attaching the first end of the spring to a support and of positioning the support and the rigid element in an initial relative position in which a coupling member, carried by the spring at its second end, is located on one side of a stressing ramp which is opposite a specific recess in the rigid element and from which the rigid element and the support can undergo a relative movement (MR) in a first direction (D1). A relative movement is applied between the support and the rigid element in the first direction so that the coupling member comes to bear against the stressing ramp and then follows this stressing ramp, which is configured to thus move the coupling member towards the axis of rotation by stressing the spring. The relative movement is continued until the coupling member penetrates at least partially into the specific recess.
