Abstract:
1. A correction mechanism for a function display indicator for a movement or a timepiece, wherein said movement or said timepiece includes, directly or indirectly mounted on a plate: first control means for at least a first function, connected to first display means and capable of occupying a let down position or at least one wound control position; second control means for a second function, distinct from said first function, connected to second display means and capable of changing, under the effect of an action by a user, from a let down rest position to a wound control position for the instantaneous release of said second function, wherein at the end of said instantaneous release, said second control means is returned to said let down rest position by return means; said second control means is distinct from said first control means; display means for a third function, different from said first and second functions, formed by said indicator, which includes drive means for the driving thereof; wherein said correction mechanism includes a first mobile part, which is arranged to be driven by said first control means and occupies a letting down position when said first control means occupies said let down position, or a winding position when said first control means occupies said wound position; and wherein said correction mechanism includes a second mobile part, which is arranged to be driven towards an actuating position, by said second control means when, at the same time, said first mobile part is in said winding position and said second control means changes from said let down position to said control position, in order to modify the position of said indicator, and said second mobile part is arranged to be held in a rest position, in which said second control means does not exert any action on said indicator from which said second control means is disconnected, when said first mobile part is in said letting down position or when said second control means is in said let down position, and further wherein said second mobile part includes a second support surface, arranged to cooperate, when said first mobile part is in said letting down position, in abutment with a first support surface comprised in said first mobile part, under the action of elastic return means which is comprised in said correction mechanism and is permanently abutting against a return support surface comprised in said second mobile part; and wherein said elastic return means is arranged to push said second mobile part towards said first mobile part and to subject said second mobile part to a pivot torque that tends to move it away from said indicator.
