Abstract (en)
[origin: JP2020052047A] To provide a timepiece assembly comprising a mechanical oscillator associated with an electronic device for controlling its mean frequency.SOLUTION: A timer (2)is provided with a mechanical movement (4), which includes a mechanical resonator (14), a sensor (24) detecting oscillation of the mechanical resonator, and a braking device (26) arranged to generate a braking pulse in response to a control signal (S) provided by a control circuit (22) associated with an auxiliary oscillator. The control circuit is arranged to be capable of detecting negative or positive temporal drift in the oscillation of the mechanical resonator and to generate, in a correction period, in association with the braking device, when the temporal drift corresponds to at least a certain loss, a series of braking pulses which are applied to the mechanical resonator at a frequency F, in a given range of values which is preferably higher than a frequency F(N)=2*F0c/N, F0c being a set point frequency for the mechanical resonator and N a positive integer number.SELECTED DRAWING: Figure 1
