Electronic timepiece

An electronic timepiece comprising:

• a primary timepiece circuit unit including a frequency supply for providing a relatively high frequency signal, a frequency converter responsive to said relatively high frequency signal for providing a relatively low frequency time unit signal, timing signals, and a plurality of word timing pulses, timekeeping register means including a plurality of shift register stages responsive to said timing signals for dynamic recirculation of data stored in said timekeeping register means, said data comprising current time data and a first set of additional data, said data being stored in a plurality of data storage locations of said timekeeping register such that the contents of each of said data storage locations appear at an output terminal of said timekeeping register means during a time interval corresponding to a predetermined one of said word timing pulses, adder circuit means located in said timekeeping register means and responsive to said time unit signal for periodically updating said current time data, and display means including a plurality of display elements for displaying said time data and said first set of additional data;
• a secondary circuit unit including secondary register means comprising a plurality of register stages responsive to said timing signals of said primary timepiece circuit unit for storing data, said data comprising a second set of additional data which is stored in a plurality of data storage locations of said secondary register means such that the contents of each of said data storage locations appear at an output terminal of said secondary register means during a time interval corresponding to a predetermined one of said word timing pulses of said primary timepiece circuit unit;
• and
• control gate means for controlling the transfer of at least a portion of said second set of additional data from said secondary storage register means to said timekeeping register means to thereby replace at least a portion of said first set of additional data.
