An electronic timepiece includes a frequency supply for providing a relatively high frequency time base signal, a frequency converter responsive to the time base signal to provide a relatively low frequency time unit signal, timing signals, and a plurality of word pulses indicative of plurality of data words representing time data concerning the current time, and a set of additional data other than the time data. A primary register is arranged to store the time data and the additional data, and display means displays the time data and the additional data. An external control member is adapted to provide an input signal when actuated, and an indexing signal is generated in response to the input signal. A secondary register is arranged to store a plurality of sets of additional data and is operable to transfer each set of additional data to the primary register in a sequential manner as the first mentioned set of additional data in response to the indexing signal, whereupon each of the sets of additional data is sequentially displayed by the display means.
