TIMEPIECE REGULATING MECHANISM |
摘要 |
In a timepiece driven by a vibrator, a spring having a spring constant much lower than that of the vibrator is coupled to the vibrator. The effective length of the spring is adjustable by varying the point of contact between a regulating mechanism and the spring. Adjustment of the vibration frequency can be effected from the exterior of the timepiece and can be carried out step-wise.
