Smart watch winding device

A watch winding device, either for mechanical watches or electronic watches with a mechanical energy source, comprising at least one energy source, arranged to power at least one motor, arranged either to turn the 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, said device comprising control means which include first acoustic measuring means which incorporate sensor means for acoustic measurement of the oscillator of at least one watch placed in the winding position, said control means being arranged to analyse signals transmitted by said first acoustic measuring means and to compare said signals to desired values which can be parameterized to regulate the operation of at least one said motor by starting said motor when the 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, wherein said first acoustic measuring means are arranged in a fixed position in a base behind an entry orifice, wherein said device includes at least one acoustic duct, which places a receiving port located inside a chamber for housing a watch, in communication with a transmitting port, and wherein said control means control drive means, which determine the motion and position in space of said transmitting port, in order, during a programmed or user-initiated operation to measure the rate of a 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.
