Abstract

PURPOSE:To obtain a multi-functional analog watch which is difficult to stop at low temperature by displacing the driving timings of two or more pulse motors to reduce the load of a battery. CONSTITUTION:A signal from a crystal oscillator 1 is supplied through a frequency divider 2 to the 1st drive circuit 3 for counting and through a delay circuit 2b to a day feeding 2nd drive circuit 4. The drive circuit 3 generates drive pulses at every two seconds with phase difference of one second from its output terminals 3a, 3b to a pulse motor 5 so as to this move a hand. On the other hand, the drive circuit 4 generates similar drive pulses delayed from the output terminals 4a, 4b to a pulse motor 15 so as to thus rotate a day feed wheel 21. Thus, since the drive pulses are displaced in phase with each other, even if two pulse motors are used, it reduces the load to the battery 50 which is difficult to stop it at low temperature.
