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 horological movement includes an indicator, a mechanism for driving this indicator in jumps, a wheel platform having a first axis of rotation, a driving finger for driving the indicator, and a spring having a first end attached to the wheel platform for rotation therewith and a second end attached to the driving finger for rotation therewith.

The mechanism limits the rotation of the lever in a first direction when the spring is being loaded and the indicator is making its next jump, the lever being able to rotate in the opposite direction to the first direction, thus allowing the driving finger to radially retract, towards the first axis of rotation, under the action of a radial force exerted on this driving finger.

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.
