摘要： A mechanical time piece has a mainspring for generating a rotational force and a front train wheel for undergoing rotation in accordance with a rotational force generated by the mainspring. An escapement and speed control apparatus controls rotation of the front train wheel and has a timed annular balance for undergoing reciprocal rotational movement, an escape wheel and pinion for undergoing rotation in accordance with rotation of the front train wheel, and a pallet fork for controlling rotation of the escape wheel and pinion in accordance with rotational movement of the timed annular balance. A switch mechanism outputs an ON signal when a rotational angle of the timed annular balance becomes equal to or larger than a predetermined threshold angle and outputs an OFF signal when the rotational angle of the timed annular balance does not exceed the threshold angle. A balance rotational angle control mechanism applies a force to the timed annular balance to restrain rotation of the timed annular balance when the switch mechanism outputs the ON signal. The balance rotational angle control mechanism has a balance magnet disposed on the timed annular balance and a plurality of coils for exerting a magnetic force to the balance magnet to thereby restrain rotation of the timed annular balance when the switch mechanism outputs the ON signal and for not exerting a magnetic force to the balance magnet when the switch mechanism outputs the OFF signal.

摘要： A mechanical timepiece has a mainspring for generating a rotational force and a front train wheel for undergoing rotation in accordance with a rotational force generated by the mainspring. An escapement/speed-control device for controlling rotation of the front train wheel has a balance with hairspring for undergoing reciprocal rotational movement, an escape wheel and pinion for undergoing rotation in accordance with rotation of the front train wheel, and a pallet fork for controlling rotation of the escape wheel and pinion in accordance with rotation of the balance with hairspring. A switch mechanism outputs an ON signal when a rotation angle of the balance with hairspring becomes a predetermined threshold angle or greater and outputs an OFF signal when the rotation angle of the balance with hairspring does not exceed the predetermined threshold angle. A position-detecting device detects a position of the mechanical timepiece. A balance-with-hairspring rotation angle control mechanism applies a force to suppress rotation of the balance with hairspring when the switch mechanism outputs an ON signal in accordance with a position of the mechanical timepiece detected by the position-detecting device.
