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.
