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, including a first control 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 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 able to be actuated by a user to set this predefined duration, and a release cam indirectly controlled by the first control 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.
