Mechanical A mechanical timer for setting a snooze time for an alarm mechanism controlling a mechanical actuator cooperating with a striking mechanism controlled by a timepiece movement, comprising including a first control means able to be actuated at a first moment by a user during the playing of an alarm chime to disengage the actuator and momentarily stop the chime, and comprising timing means including a timer arranged to automatically cause the alarm chime to play again at a second moment, after a predefined duration from the first moment, this timer including a second control means able to be actuated by a user to set this predefined duration, and a release cam indirectly controlled by the first control means and arranged to control the pivoting of a hammer lever, which, depending on its angular position, releases or locks the actuator to allow or respectively prevent the playing of an alarm chime.

Disclosed is a timepiece including a case, a movement and a vibration-generating device intended to produce a sound, the latter two accommodated in the case, a device for amplifying the vibrations from the vibration-generating device, and a membrane receiving the amplified vibrations and generating a sound to outside the timepiece. The vibration-amplifying device includes a lever pivotally mounted on a support in a pivoting plane non-parallel to the plane of the membrane and actuated by a transmission member cooperating with the vibration-generating device to transmit the vibrations to the lever, the lever being integral with the membrane at least translationally in the pivoting plane so a movement of the transmission member, generated by vibration of the transmission member linked to the vibration-generating device and transmitted to the membrane by way of the lever actuated by the transmission member, generates an amplified movement of the membrane for an amplified sound.

Disclosed is a mechanical wristwatch including a case having a middle, a back cover and a bezel, a vibration-generating device for generating vibrations which are intended to produce at least one sound, which is accommodated in the case, a vibration-amplifying for amplifying the vibrations generated by the vibration-generating device, and a membrane arranged to receive the amplified vibrations and generate a sound from the inside to the outside of the wristwatch. The vibration-generating device is a rotary element having a reading surface including at least one groove arranged to generate sounds. The wristwatch also includes a unit for rotationally driving the rotary element, an actuator for such unit, and a transmission member arranged to cooperate with the rotary element to transmit, to the vibration-amplifying device, the vibrations generated by the groove during rotational movement of the rotary element.
