Abstract (en)
[origin: WO0101203A1] A mechanical timepiece, comprising a timed annular balance rotating angle control mechanism formed so that it generates a static electricity when the rotating angle of a timed annular balance (140) comes to a specified threshold value or higher and does not generate the static electricity when it does not exceed the specified threshold value, wherein the control mechanism can be controlled so that the deflection angle of the timed annular balance comes within a specified range, whereby the mechanical timepiece becomes accurate because a variation in its rate is small even when a time elapses after it is fully wound.
