Accuracy Measurement System for Mechanical Watch via the Computer's Built-in Microphone

This paper presents a new system for measuring the accuracy of mechanical clocks using the computer's built-in microphone. The system is based on the analysis of acoustic signals generated by the balance wheel of the watch and offers an innovative and affordable method to assess the dynamic accuracy of time in real conditions. The accuracy of a mechanical watch is an important parameter related to multiple factors such as oscillations, shocks and vibrations that affect its precise functioning. In this context, the developed system provides a readily applicable alternative to measure and improve the accuracy of watches using standard computational devices and acoustic analyses. The proposed methodology contributes to expanding the possibilities of investigating the dynamic characteristics of mechanical watches in the scientific community and metrology research.
