Timepiece (1) including a case (11) in which systems (3, 5, 7, 9) are mounted for operating the timepiece, controlled by control members (15, 21, 19) that project from the case, at least one of the control members (15, 19, 21) cooperating with an anti-shock device (33, 35) mounted in the case (11) and including a main component (91, 111), which is moveably mounted relative to the case (11), characterized in that the main component (91, 111) includes a permanent mechanical connection with the part (63, 41) of each system (25, 23) to which the at least one control member is attached, which enables the component to be reversibly uncoupled from the at least one control member (15, 19, 21) when a force greater than a predetermined threshold is exerted on the at least one control member and in that the mechanical connection is of the sliding type, and includes a jumper spring (95, 115) elastically mounted relative to a pin (96, 116).
