    • 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.

    • A method and system for testing the accuracy of the oscillators of electronic clocks includes transforming a frequency signal corresponding to the output of a clock oscillator into a non-sinusoidal signal having the same frequency as the frequency signal and filtering the non-sinusoidal signal to pass a component of the non-sinusoidal signal having a frequency associated with a reference frequency to be compared with the signal passed by the filter such that clock oscillators operating at various frequencies of which the reference frequency is an integral multiple can be tested since the non-sinusoidal signal, which is preferably a sawtooth signal, contains harmonic components corresponding to the reference frequency.
