Abstract: A timepiece assembly includes a watch having a mechanical movement and an analogue time display, the running of which is set by a mechanical resonator, and a support for the watch. To correct a time displayed by the analogue display, the timepiece assembly includes a correction system which is formed by a mechanical device incorporated into the watch and by an electrical device incorporated into the support. The mechanical device includes a magnet supported by an elastic blade and is arranged in the watch to brake the oscillating mechanical resonator, for example by applying periodic braking, or to momentarily stop its oscillation by exerting a magnetic force on the magnet with a magnetic field produced by a coil of the electrical device and passing through the case of the watch, to carry out essentially a set correction of the time displayed.

Abstract: A horological movement includes an analogue time display, a gear train, a barrel driving the analogue display via the gear train, and an oscillator formed of a resonator, including a balance and a piezoelectric spring, and a mechanical escapement coupling the balance to the gear train. This horological movement further includes an electric energy source which is associated with the electronic control circuit, which is arranged to be able to control the application of an electrical supply voltage to the piezoelectric spring to excite the oscillator to obtain a functional oscillation of the resonator and then to maintain this functional oscillation. The mechanical escapement is an escapement for counting the alternations of the functional oscillation, to pace the running of the horological movement, without the resonator being able to receive from the barrel via this mechanical escapement enough mechanical energy to maintain the functional oscillation.
