An electrically energized timepiece movement is provided with motion work the form of a planetary train entirely supported on the frame of a driving motor. Coaxial planet pinions are excentrically located on a minute wheel, one planet pinion engaging a fixed central gear and the other engaging the hour wheel.

An electronic timepiece having an analog time display and a digital alarm setting system for actuating an alarm at a preset time. The timepiece includes a high-frequency time base whose output is applied to a frequency converter yielding low frequency timing pulses, these being applied to a motor for driving the hour and minute hands through a gear train. The alarm setting system includes an electro-optical digital display whose electronic actuator responds to the same timing pulses to provide a digital display concurrent with the analog display, and a microprocessor associated with a data memory adapted to store the digital value of any selected time setting. The microprocessor compares the existing time expressed as digital data with the stored digital value to produce a representative output signal when the existing value is coincident with the stored value. The output signal acts to trigger an alarm generator to produce an alarm for a predetermined period.

An electronic clock, particularly a quartz clock, with a timer signal transmitting stage, an indicator system which at least contains a minute counter and an hour counter, as well as a decoding stage and a digital indicator board, and an alarm system which at least contains a presettable counter associated with the minutes and a presettable counter associated with the hours, the outputs of which presettable counters are able to be locked on the indicator system, and a coincidence stage for comparison of the output signals of the counters of the indicator system with those of the alarm system. Each counter of the alarm system constitutes a forward-rearward-counter, and switches are provided for selection of the counting direction.

An electronic clock having a clock circuit in which reference clock pulses are frequency divided so as to be applied to a time indicating device for stepwise switching the time indication therein one by one unit of time for indicating the time, and the time indication is corrected stepwise one by one unit of time in timed relationship to the reference clock pulses by applying time correction pulses to the clock circuit until the correction of time is achieved. The device for correcting the time indication comprises a time correction signal generating circuit capable of applying time correction pulses of variable frequency to the clock circuit in timed relationship to the reference clock pulses so that the speed of the stepwise correction of time can be arbitrarily adjusted. The clock has a timer and the device for correcting the indication of time of the electronic clock can be used for correcting the time of the timer at which the timer is actuated, by switching the indication of time in the indicating device by the action of the switch means together with the readjustment of the set timer time in the clock circuit.

An electronic timepiece having a first display unit which indicates the present time by means of digital values, and a second display unit of the hand type which displays the time set by an additional function such as alarm function by means of one or more hands.
