1. A state of display correction device for correcting the state of display of a watch or respectively of a movement, said watch or respectively said movement including at least one basic oscillator arranged to generate oscillation at a nominal frequency N0, with an initial variation of rate value DI, the state of display correction device comprising:
a state of display correction oscillator arranged to generate oscillation at a correction frequency NC; and
control means arranged to control the oscillation of said state of display correction oscillator,
wherein said state of display correction device is arranged to subject said entire watch or respectively said entire movement to oscillation generated by a master oscillator and to a modulated motion generated by said state of display correction oscillator, and
wherein the control means is interfaced with means for measuring the state of said watch or respectively of said movement, comprised in said state of display correction device.
