Abstract
There is provided an electronic timepiece basic circuit comprising a pulse generating circuit for generating 1 Hz pulses, a first terminal group having a plurality of terminals including a terminal connected to the output terminal of the pulse generating circuit, a second terminal group having terminals to be connected to the terminals of the first terminal group, respectively, 10 scale counters coupled with the second terminal group, 6 scale counters connected to the 10 scale counters, a display unit, and a decoder which is coupled with the 10 scale counters and the 6 scale counters and decodes the contents of the 10 and 6 scale counters and delivers the decoded contents to the display unit. The first and second terminal groups are properly coupled to each other. The combination of the 10 scale counters and the 6 scale counters is properly modified so as to form a 12, 24, or 60 scale counter, as necessary.
