Method and system for winding and for performing diagnostic of automatic watches

Abstract

A method for winding and for performing diagnostic of an automatic watch, the method comprising recording sound signals of a watch by means of an acoustic sensor (S10), determining, on the basis of the recorded sound signals, a first group of characteristics comprising at least one of the physical characteristics of the watch (S12), determining, on the basis of the first group of characteristics, the type of the watch (S14), continuously rotating the watch until the winding level of the watch mechanism reaches 100% (S20), measuring again sound signals of the watch and determining a second group of characteristics comprising at least one of the physical characteristics of the watch mechanism corresponding to its winding level 100% (S28). The method comprises maintaining the watch in a resting position for a predetermined period of time, thereby providing a given winding level to the watch mechanism (S30), measuring, after said period of time, sound signals of the watch by means of the acoustic sensor, and determining, at the given winding level of the watch mechanism, at least one characteristic belonging to the second group of characteristics (S32), measuring ambient temperature of the watch (S34), pairing said characteristic determined at the given winding level and the measured temperature (S36), determining the relationship between the given physical characteristic and the given temperature from the data pairs consisting of the different ambient temperatures and the characteristics determined at the given winding level (S38), - calculating, on the basis of the relationship thus determined, the value of the given physical characteristic belonging to a given temperature (S39). A system (1) for performing the method according to any one of claims 1-5, the system (1) comprising a watch winding device (10) having at least one acoustic sensor (12) for measuring sound signals of a watch, a temperature sensor (13) for measuring the ambient temperature, a control unit (14), a data storage unit (16) and an interface (18), a server (80) in wireless communication with the interface (18) including a database (90) and an artificial intelligence-based learning and analysis algorithm installed thereon, a data input and display device (100) in wireless communication with the server (80).
