Alarm signaling circuit for timepiece

An alarm signaling circuit for a timepiece having settable first and second alarm signal periods and which is capable of external and optional determination of alarming volume comprising:

• a volume control circuit having a variable volume controller which can be externally adjustable and a fixed volume setting means which determines a constant volume;
• a change over switch which selectively changes between said volume controller and said fixed volume setting means in response to a change over control signal;
• and
• a change over control circuit which has a timer section for measuring alarm signaling time and for supplying said change over control signal to said change over switch after a predetermined passage of time from a start of an alarm signaling;
• whereby alarm signaling action at a certain volume is established by said variable volume controller during said first alarm signaling period and alarm signaling action at a fixed alarming volume is determined by said fixed volume setting means in a consecutive said second alarm signaling period.
