摘要： A device for measuring a characteristic magnitude of the operation of a timepiece movement is disclosed, in which measuring pulses are generated in response to vibrations of the movement for measuring the time intervals between vibrations reflecting the operation of the movement. The generation of measuring pulses is allowed only within a short window of constant duration following a blocking period which starts after the occurrence of a measuring pulse and has a duration depending on the duration of the penultimate preceding time interval between measuring pulses.

摘要： A method of and apparatus for measuring the amplitude of oscillation of the balance of a timepiece movement having an escapement adapted for disengagement and engagement, successively, the balance having a predetermined angle of lift. The time intervals between successive disengagement and engagement are measured, as are the durations of vibration of the balance. The number of pulses of a first frequency which are produced during at least one of the measured time intervals is counted. The number of pulses of a second frequency produced during at least one of the vibration durations also is counted. The first and second frequencies have a predetermined relationship with respect to each other. The number of counted pulses of the second frequency is divided by the number of counted pulses of the first frequency to thereby attain a quotient which is equal to the amplitude of oscillation.
