Abstract (en)
[origin: WO2021121711A1] The watch (2) is formed by a mechanical movement incorporating a mechanical resonator (14). It comprises a time display (12) and a device for correcting the displayed time, which is formed by a receiver (30) of an external correction signal which is supplied by an external electronic device (40) (in particular a mobile telephone), a braking device (22A) for braking the mechanical resonator and an electronic control unit (28). The correction device is designed to be able to correct the displayed time as a function of a temporal error (delay or advance) contained in the external correction signal. In order to do this, the correction device is designed such that the braking device can act on the mechanical resonator during a correction period in order to vary the rate of the driving mechanism of the display, so as to correct at least the major part of the temporal error in the displayed time.
