To control the rate of a mechanical watch with high precision. [Solution] In mechanical watches, A sensor detects the vibrations of the balance, and the cumulative frequency is compared with the clock cumulative frequency of the reference oscillator to calculate the rate error. Based on this error, a control method is determined, and mechanical energy is injected into the balance by an actuator to control the rate. For even more precise control, abnormal vibrations are recorded to evaluate the reliability of the measurements and adjust the control strategy accordingly. In addition, if sensor detection is difficult, it is supplemented by phantom counts estimated from the reference oscillator. If necessary, it is also possible to identify external factors using auxiliary sensors. When high reliability is required, sensors with different detection principles can be duplicated and cross-verified. This configuration enables implementation at various levels, from basic rate control to advanced adaptive control.
