1. A universal device for preparation of a watch including a first crown for gain/loss correction and an oscillating resonator arranged to generate an oscillation at a nominal frequency N0, comprising:
means for winding and for correcting the gain/loss of said watch, comprising at least one robotic manipulator for operating said first crown;
an adjustment device, which includes at least one gain/loss correction device for correcting the gain/loss of said watch, which includes a gain/loss-corrector oscillator arranged to generate an oscillation at a correction frequency NC and to subject said watch to an oscillation at said correction frequency NC and/or to a modulated movement, said gain/loss correction device comprising gain/loss control means arranged to control the oscillation of said gain/loss-corrector oscillator and interfaced with gain/loss measuring means comprised in said universal preparation device for measuring the gain/loss of the watch,
wherein said gain/loss correction device includes an automatic winder for mechanical or automatic watches, and includes at least one watch-holder stand, which is subjected to the oscillations and/or movements generated by said gain/loss-corrector oscillator.
