    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 power source comprised of a mainspring for undergoing rewinding movement to generate a rotational force. A front train wheel undergoes rotation in accordance with a rotational force generated during rewinding movement of the mainspring. An escapement/speed-control device controls rotation of the front train wheel. The escapement/speed-control device has a balance with a hairspring for undergoing alternately repeating rotational movement in left and right directions. An escape wheel and pinion undergoes rotation in accordance with rotation of the front train wheel. A pallet fork controls rotation of the escape wheel and pinion in accordance with rotational movement of the balance. A switch mechanism outputs an ON signal when a rotation angle of the balance reaches a predetermined threshold angle or greater, outputs an OFF signal when the rotation angle of the balance does not exceed the predetermined threshold angle. A rotation angle control mechanism supresses rotation of the balance when the switch mechanism outputs an ON signal.

    摘要： According to a rate adjusting method, the movement of a mechanical timepiece is first assembled. The assembled movement is then disposed in a vertical position, and the rate is measured with respect to a plurality of vertical positions. On the basis of the result of this rate measurement, the magnitude and direction of the positional difference vector are calculated. On the basis of the result of this calculaton, the amount of weight to be added to or subtracted from the annular balance of the movement is calculated and the positions on the annular balance where this amount of weight is to be added to or to be subtracted from is calculated. Based on the results of these calculations, the amount of weight is added to or subtracted from the annular balance at the calculated positions.
