Abstract

A multifunction correction device (100) for a case (2) of a timepiece including a horological movement (1) having at least one function corrector (10, 12) for carrying out various functions of activating, selecting, resetting and/or correcting a piece of information derived from the current time of the horological movement. A control member (130) is capable of moving in rotation about the axis of revolution (X-X) of a control stem (120) between a plurality of angular positions and a protrusion (123) is configured such that the rotation of the control member (130) modifies the angular position of the protrusion (123) about the axis of revolution (X-X) and relative to the horological movement (1).
