An object of the present invention is to provide a timepiece rate stabilizer that uses an external reference but does not directly inject mechanical vibrations into the balance, and that can stabilize the rate over a long period of time with extremely low power consumption. [Solution] We provide a rate stabilizer for mechanical watches that is based on a statistical driving method with constant pulse width and amplitude and autonomously switches between four modes based on actual current consumption: normal mode using phase shift, ΔΣ1 bit stream mode, low detune frequency hopping mode, and chirp search mode.Without modifying the hairspring at all, we achieve both rate stability and low power consumption while maintaining constant instantaneous energy.
