An alarm signaling circuit for a timepiece including a volume control circuit having a variable volume controller which can be externally adjusted and a fixed volume setting means which determines a constant volume, a change over switch which selectively changes the controller and the setting means, and a change over control circuit which has a time section for measuring an alarm signalling time and which supplies a change over control signal to the change over switch after a predetermined passage of time from the start of alarm signaling. The alarm signaling circuit performs the alarm signaling action at a certain volume established by the variable volume controller during a first alarm signaling period from a start of alarm signaling till the predetermined passage of time and further performs the alarm signaling action at a fixed alarm volume determined by the fixed volume setting means in a consecutive second alarm signaling period.
