A monolithic timepiece mechanism made in a single plate of material, including a frame, a first elastic suspension and an inertial regulating member which is connected to the frame by the first elastic suspension so as to be able to oscillate, a blocking mechanism having a blocking member connected to the frame by a second elastic suspension. The blocking member is controlled by the regulating member to be able to regularly and alternatively hold and release a energy distribution member and to regularly transmit energy from the energy distribution member to the regulating member.

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

A mechanical timepiece movement in the form of a modular unit. The movement includes at least one modular unit for performing a particular timepiece function, which is irremovably pre-adjusted by irremovably securing adjustment and/or assembling components included in the functional module after the particular horological function has been adjusted and function checked on the test bench. The pre-adjusted functional module is irremovably secured to a plate included in the movement or included in another pre-adjusted functional module of the movement, or irremovably secured to another pre-adjusted functional module included in the movement.
