Smart watch winding device

A watch winding device comprising:

• at least one energy source, arranged to power at least one motor, arranged either to turn a winding crown of a manually wound watch, or to drive at least one oscillating weight of a self-winding automatic watch, or to rock at least one self-winding automatic watch;
• control circuitry which includes first acoustic measuring circuitry which incorporates a sensor for acoustic measurement of an oscillator of at least one watch placed in a winding position, said control circuitry being arranged to analyse signals transmitted by said first acoustic measuring circuitry and to compare said signals to target values which correspond to the watch winding device to regulate an operation of at least one said motor by starting said motor when an operating amplitude of said oscillator is less than or equal to a first, minimum value, and by stopping said motor when the operating amplitude of said oscillator is higher than or equal to a second, maximum value, said first acoustic measuring circuitry arranged in a fixed position in a base behind an entry orifice;
• and
• at least one acoustic duct, which places a receiving port located inside a chamber for housing the watch, in communication with a transmitting port, and wherein said control circuitry controls a drive motor, which determines the motion and position in space of said transmitting port, in order, during a programmed or user-initiated operation to measure the rate of the watch fixed inside said housing, to position and immobilise said transmitting port in an indexing position facing said sensing opening and in immediate proximity to the latter or to the contact thereof.
