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.

Winding device (1000) including motorisation means (2) driving a watch holder (1) carrying at least one automatic watch (100) with a movable oscillating mass, and measuring means (3) measuring the amplitude of the resonator of each watch (100), and watch (100) identification means (300), providing the identification of a particular watch (100) to control means (200) including an internal database (400) with the history of the amplitude measurements of the resonator of this particular watch (100) and/or the value of its nominal amplitude, and/or communication means (500) communicating with an external database (600) for extracting these values.

A timepiece movement includes: a barrel wheel; a ratchet wheel; a rotary weight; a transmission wheel that causes the ratchet wheel to rotate; a pawl lever that engages with the transmission wheel, is interlocked with the rotary weight, and performs forward/backward movement in directions of approaching and moving away from the transmission wheel; a base panel; and a wheel train bearing provided between the base panel and the rotary weight. The pawl lever and the transmission wheel are positioned between the base panel and the wheel train bearing. The transmission wheel is pivotally supported by the wheel train bearing. The wheel train bearing is provided with a release portion for releasing the pawl lever and the transmission wheel from engagement therebetween by moving the pawl lever.
