A watch formed by a mechanical movement incorporating a mechanical resonator, including a display displaying the actual time, a correction device formed by a device for detecting the passage of at least one hand through at least one reference time position and by an electronic correction circuit allowing an overall time error for the display to be determined, and a device for braking the mechanical resonator. The correction device is arranged such that it can correct the actual time displayed as a function of the overall time error (loss or gain) previously determined. For this purpose, the correction device is arranged such that the braking device can act on the mechanical resonator during a correction period to vary the running of the drive mechanism of the display, in order to correct the actual time displayed.
