Abstract

PURPOSE: To establish the analog chronograph crystal watch by using specific chronograph mechanism.
CONSTITUTION: The chronograph converter 28 in response to the signal having shorter period than the watch consisting of the coil 45, stator 43, rotor 18, chronograph gears 17 to 13, and gear 12 as minute pointer indication, is connected to the frequency division circuit 22 via the chronograph drive circuit 27 and gate circuit 33. Thus, when the external operation member 31 such as stem and botton is operated, the gate circuit 33 is operated with the internal input signal 32, and frequency division signal passing through the gate circuit 33 is shaped at the chronograph drive circuit 27 similarly as normal watch, it is converted into the rotary movement with the chronograph converter 28, and the measuring tims is indicated with the chronograph indication wheels 30 via the chronograph wheels 29.
