ABSTRACT:
A time synchronizer is disclosed for an analog timepiece. An electronic circuit 20 is disclosed which generates a direct current pulse upon receipt of an input signal from a remote source. Circuit 20 is operable in two separate modes through outputs from a timekeeping output 25 and a time correction output 38. The time correction mode operates through a feather switch 35 having a contact 35b which rides in a cam 34 of a rotating wheel 33 which moves in synchronization with hands 12A and 12B of an analog timepiece.
