An alarm clock includes a time indicator, a first alarm for sounding a first alarm at a preset time, a manual rotary bezel provided rotatable relative to the time indicator outside same for setting a time elapsing from the alarm time, and a second alarm for sounding a second alarm when the time set by the rotary bezel has elapsed since the preset time. After the first alarm is sounded at the alarm time, and after the time set by the rotary bezel has elapsed, the second alarm is sounded. The time interval after which the second alarm is sounded is set by a simple operation and two-staged sounding ensures proper awakening of the sleeper.

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.

An alarm signalling electronic timepiece including an alarm signalling circuit which generates alarm signal at a preset hour, and a sound circuit which generates signalling sound by the alarm signal. This timepiece includes a timer counter which can memorize and subtract preset time and which can supply the alarm signal to the sound circuit after the set time elapses from the start of down count from a a time start circuit which holds the time memorized in said timer counter until the alarm signal from the alarm signalling circuit changes and which starts counting in said timer counter when the alarm signal changes, and external switches which externally switch over to work or cancel said time start circuit, whereby plural and different alarm signalling hours can be set with more simplicity.

The combination of a personal electronic clock related device with a limited automatic multiple recall alarm suspension control means comprising an involuntary alarm suspension control circuit including an extended audio control means and a governing means. The personal electronic clock related device having internal audio alarm control means and internal sound emission means for allowing the emission of an audible alarm call sound to be broadcast at a set time. The extended audio control means is coupled with the internal audio alarm control means, and further coupled with the internal sound emission means interrupting the emission of the audible alarm call sound from being broadcast. The governing means is jointly coupled with the internal audio alarm control means and simultaneously activated when the audible alarm call sound is to be broadcast. The governing means including primary and secondary output control means cooperatively allowing an involuntary control signal to be discharged. The extended audio control means is further coupled in connection with and activated by the involuntary control signal for allowing the emission of the audible alarm call sound to be broadcast. The primary output control means are arranged specifically allowing the audible alarm call sound to be very infrequently momentarily broadcast for extremely brief periods of time. The secondary output control means allowing the audible alarm call sound to be continuously broadcast after the audible alarm call sound has been accordingly broadcast a preceding number of times, whereby, for consistently allowing the emission of the audible alarm call sound produced by the personal electronic clock related device to be momentarily broadcast and then involuntarily suspended for a substantially lengthy period of time for a limited number of times prior to being continuously broadcast, according to the direction of the limited automatic multiple recall alarm suspension control means. The limited automatic multiple recall alarm suspension control means may further include a means for optionally allowing the personal electronic clock related device to be independently operated.
