ABSTRACT:
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.
