ABSTRACT:
An alarm device of a clock has an alarm time detection mechanism coacting with the time wheels of the clock for detecting a preset alarm time and sound an audible alarm. The audible alarm is terminated in response to manual depression of a call time setter pin and with each depression of the pin, the alarm time detection mechanism is reset to detect a new alarm time so that the new alarm time is determined by the number of times the pin is depressed. A time indicating mechanism indicates the preset alarm time and is automatically adjusted to display the new alarm time dependent upon the number of depressions of the call time setter pin.
