Abstract

A motor normally drives a gear-train which controls the hands when the motor is acted upon by pulses it receives from a driving circuit and which come from a divider and a quartz oscillator. In order to set an alarm to the desired time, a stem is moved by means of a crown to a setting position. The gear-train is then driven by a pinion and a wheel meshing with one another. The alarm time is recorded by a counter circuit owing to pulses supplied by a contact of a rotary detector. This time is stored in a memory when a push button is pressed. After the hands are returned to a position indicating the correct time of day, the counter circuit counts the elapsed time, and the alarm is set off when a coincidence circuit detects coincidence between the count of the counter and the data stored in the memory.
