Abstract:
PROBLEM TO BE SOLVED: To provide a device for checking the self-identification information of a timepiece with a mechanical movement.SOLUTION: A mechanical movement (1) has a checking device which is a passive indicator element (2). The passive element (2) is fixed to a fixed support portion (3) of the mechanical movement. The passive element may be a strip (2) or a plate fixed to the fixed support portion of a regulating member (4), and is configured to vibrate according to one or more clearly defined vibration frequency components following the vibrations of the mechanical movement. The vibration frequency components of the strip or the plate define an acoustic signature specific to a timepiece to allow the authenticity of the timepiece to be determined by a measurement of the acoustic signature using an acoustic measuring system.
