Abstract
The present invention provides a timpiece including clock and timer sections which can be operated solely or in association with each other. When the clock and timer sections are combined with each other, the start of the timer section is controlled by an alarm signal from the clock section such that two different alarm functions can be attained. The alarm signal is preferably in the form of an alarm output or alarm pause output. The clock and timer secitons may be connected into a unit or mechanically disconnected from each other. When the clock section can be separated from the timer section, the state of connection therebetween and the life of a battery used can warningly be indicated.
