A method for operating a timepiece transmission system comprising: - a frame , - a first mobile comprising a first toothset ; - a second mobile comprising a second toothset , said second mobile meshing with the first mobile and being intended to be driven by the first mobile; and - a third mobile comprising a third toothset , said third mobile being intended to mesh with the second mobile and intended to be driven by the second mobile; the meshing of the first toothset with the second toothset being irreversible, the first mobile being able to drive the second mobile in both directions and the second mobile being able to drive the first mobile only in one direction, and the meshing of the third toothset with the second toothset being irreversible, the third mobile being able to drive the second mobile in both directions and the second mobile being able to drive the third mobile only in one direction, the first mobile being pivoted about a first staff on the frame, the second mobile being pivoted about a second staff on the frame, and the third mobile being pivoted about a third staff on an element that is movable relative to the frame, or an operating method of timepiece mechanism comprising such a timepiece system or an operating method of timepiece comprising such a timepiece system, the method comprising the following steps: - moving the movable element from a first position, in which the second and third toothsets mesh, to a second position, in which the second and third toothsets do not mesh; - correcting a timepiece indication by rotating the second mobile in a first direction and in a second direction, - moving the movable element from the second position to the first position. - a frame , - a first mobile comprising a first toothset ; - a second mobile comprising a second toothset , said second mobile meshing with the first mobile and being intended to be driven by the first mobile; and - a third mobile comprising a third toothset , said third mobile being intended to mesh with the second mobile and intended to be driven by the second mobile; the meshing of the first toothset with the second toothset being irreversible, the first mobile being able to drive the second mobile in both directions and the second mobile being able to drive the first mobile only in one direction, and the meshing of the third toothset with the second toothset being irreversible, the third mobile being able to drive the second mobile in both directions and the second mobile being able to drive the third mobile only in one direction, the first mobile being pivoted about a first staff on the frame, the second mobile being pivoted about a second staff on the frame, and the third mobile being pivoted about a third staff on an element that is movable relative to the frame, or an operating method of timepiece mechanism comprising such a timepiece system or an operating method of timepiece comprising such a timepiece system, the method comprising the following steps: - moving the movable element from a first position, in which the second and third toothsets mesh, to a second position, in which the second and third toothsets do not mesh; - correcting a timepiece indication by rotating the second mobile in a first direction and in a second direction, - moving the movable element from the second position to the first position. - moving the movable element from a first position, in which the second and third toothsets mesh, to a second position, in which the second and third toothsets do not mesh; - correcting a timepiece indication by rotating the second mobile in a first direction and in a second direction, - moving the movable element from the second position to the first position. <EOS>
