Two-directional date corrector mechanism for a date mechanism, date mechanism, timepiece

A date mechanism of a timepiece including a two-directional date corrector mechanism controlled by an actuating pull-out piece pivotally mounted about a first pivot axis, for a date mechanism of a timepiece, said date mechanism comprising:

• a twenty-four hour wheel driven by a movement of said timepiece;
• a date updating finger mounted to pivot integrally with said twenty-four hour wheel about a second pivot axis;
• a date driving star-wheel;
• and
• said corrector mechanism comprising a corrector star-wheel distinct from said date driving star-wheel, said corrector star-wheel pivotally moveable about a third pivot axis distinct from said second pivot axis and located between said finger and said date driving star-wheel,
• wherein said corrector star-wheel is permanently meshed with said date driving star-wheel, a daily motion of said finger to update a date being only transmitted to said date driving star-wheel via said corrector star-wheel, and
• wherein said corrector star-wheel is arranged to be uncoupleable from said finger under an action of an uncoupling mechanism controlled by said pull-out piece, said uncoupling mechanism having at least two positions including at least a first coupling position in which said corrector star-wheel is arranged to mesh with said finger, and at least a second uncoupling position in which said corrector star-wheel is released from said finger to enable the date to be corrected by pivoting of said corrector star-wheel causing said date star-wheel to pivot, and
• wherein said second pivot axis of said finger is fixed, whereas said third pivot axis of said corrector star-wheel is moveable, and
• wherein said uncoupling mechanism includes a mechanism of relative movement of said third pivot axis of said corrector star-wheel relative to said second pivot axis of said finger, to move said third pivot axis.

• the date mechanism includes only two layers:
• an under layer including the twenty-four hour wheel and at least a part of the pull-out piece, and
• an upper layer including the finger, the corrector star-wheel, and the date driving star-wheel.
