Abstract (en)
[origin: US2022107607A1] A coiling limitation device for a timepiece barrel includes at least one non-return notch arranged to cooperate with a sliding flange of the spring of the barrel, which is integrated in a watch including a resonator cooperating with an escapement mechanism. This device includes an acoustic device for the acoustic monitoring of the coiling of the barrel of a watch positioned on a receptacle included by the device, which acoustic devices are arranged to identify a click noise during each start of cooperation between the sliding flange and a notch. The device includes piloting devices arranged to stop the coiling of the barrel at the instant of the perception of the click noise or the repetition of the click noise.
