Abstract: The timepiece comprises at least one pushbutton (9), at least one control member actuable by the pushbutton (9) and a device (10) for locking the pushbutton (9), and is characterized in that the locking device (10) is arranged to permit the pushbutton (9) to occupy an unlocked axial position, from which it can be pressed to actuate the control member, and a locked axial position, nearer the interior of the timepiece than the unlocked axial position and in which the control member is not actuated.

Abstract: The timepiece comprises a case (1), a mechanism (6) disposed in the case (1) and a rotatable control member (10) manipulable by a user, and is characterized in that the rotatable control member (10) is movable in translation relative to the case (1) in a direction substantially perpendicular to the axis (A) of the rotatable control member (10), between first and second positions, and in that in at least one of these first and second positions a rotation of the rotatable member (10) controls a function of the mechanism (6).
