Claims

[Scope of Claim for Utility Model Registration] A first gear train that normally displays the time using a pointer;
a second wheel train that performs a clock operation different from the normal time and some digits of the normal time; a first motor that drives the first wheel train; and a second motor that drives the second wheel train. a motor; a first motor that drives the first motor;
a second drive circuit that drives the second wheel train; a switch selection circuit that outputs a signal by operating an external switch; and a plurality of pulses that drive the motor based on the output of the switch selection circuit. A signal is selectively output to the first and second drive circuits to display the normal time in the first wheel train and the second wheel train or to perform a timekeeping operation different from the normal time in the second wheel train. The first wheel train drives the hour and minute hands of the normal time display, and the second wheel train drives the second hand of the normal time and a timekeeping operation different from the normal time, and the second hand of the timekeeping operation different from the normal time. An electronic watch characterized by being configured to drive hour and minute hands on a display.
