An assembly including horological movement support, a motor plate of a timepiece and a fastener fastening the support to the plate. The fastener includes a self-tapping screw having a body that passes through a hole in the support. A recess in the plate or support is tapped when the screw is screwed into the recess. The shape of the recess has a variable width, which is wider at the opening extending to a smaller diameter at the bottom of the recess, the shape corresponding to that of the body of the screw.

A bolt (10) configured to limit the axial travel of a moving body (21) of a horological movement (20). The bolt includes a head (11) arranged at the end of an arbor (12) extending according to a longitudinal axis of revolution, the head (11) extending radially with respect to the arbor (12) and including over a portion of its periphery, a radial addendum (110) configured to be arranged opposite said moving body (21), and including, at the interface with the arbor (12), a bearing base (111) through which the bolt (10) is configured to rest against a structure (22) of the horological movement (20).

The invention concerns a device for holding a wheel set of a timepiece movement comprising a lever, intended to be mounted to slide via guide means on the main plate of the timepiece movement between a first and a second position.

According to the invention, the lever comprises, at a first end, a locking beak intended to cooperate with means for holding the wheel set to hold and to guide the wheel set in rotation in the first position and to leave the wheel set free in the second position, the lever being arranged to be able to move in translation, between the first position, called the retracted position, and the second position, called the deployed position.

A motor module for a horological movement, the motor module including a plate bearing one or more cogs, and a cog bridge mounted on the plate, wherein the cog bridge includes a device for clipping the cog bridge onto the plate.
