Method for checking the identity of a mechanical watch movement

摘要

The mechanical movement includes a checking device which is a passive indicator element. The passive element is fixed to a fixed support portion of the mechanical movement. The passive element may be a strip or a plate fixed to the fixed support portion of a regulating member and configured to vibrate according to one or more clearly defined vibration frequency components following the vibration of the mechanical movement. The vibration frequency components of the strip or plate define an acoustic signature specific to the timepiece to allow the authenticity of the timepiece to be determined by a measurement of the acoustic signature using an acoustic measuring system.

1. A method for allocating and for checking a unique code of acoustic identification of a timepiece, which includes a mechanical movement provided with at least one passive indicator element, which is configured to vibrate according to one or more clearly defined vibration frequency components following a vibration of the mechanical movement, wherein the method includes:
starting to operate the mechanical movement to induce shocks in an escapement wheel sets, generating a vibration of the passive indicator element via the vibration of the mechanical movement to define an acoustic signature specific to the timepiece, and checking the code of the acoustic identification of the timepiece by an acoustic measurement of vibration frequencies of the passive indicator element, wherein the passive indicator element includes one end which is fixed to a fixed support portion of the mechanical movement such that the passive indicator element lowers a damping of a signal generated by the mechanical movement.
