<p>A mechanical timepiece, comprising a posture detection part (361) for detecting the posture of the mechanical timepiece, a timed annular balance rotation detection part (276) which is installed to detect a swing angle of the timed annular balance by detecting a variation in static electricity capacity between a timed annular balance static electricity capacity electrode part (240) and a static electricity capacity electrode for detection (250) which varies according to the operating condition of the timed annular balance (140), and a braking part (146) which, when the swing angle of the timed annular balance (140) detected by the timed annular balance rotation detection part (276) is equal to or more than a preset set angle, is formed so that a force to suppress the rotation of the timed annular balance (140) is given to the timed annular balance (140) based on the signals concerning the posture of the mechanical timepiece detected by the position detection part (361).</p> |
