Claims

[Scope of utility model registration request]

A time standard 21, a frequency divider circuit 22 that divides the frequency of the output signal of the time standard, a drive circuit 23 that operates based on the output signal of the frequency divider circuit, and a coil 41 and a rotor 6 driven by the drive circuit. A timepiece mechanism consisting of a timepiece step motor 28 comprising a plate-shaped stator 42, and an indicator wheel train 25, 26 that is driven by the step motor and operates a timepiece second hand 44 a timepiece minute hand 62 a timepiece hour hand 61; and a gate circuit 33 that passes a signal at an intermediate stage of the frequency dividing circuit in response to an input signal generated by an external operating member 31; a chronograph drive circuit 27 that operates in accordance with an output signal of the gate circuit; activated coil 45
a chronograph step motor 28 consisting of a rotor 18 and a plate-shaped stator 43; and a chronograph second hand 14a which is driven by the chronograph step motor and has a driving cycle of 1 second or less.
The chronograph mechanism includes a chronograph indicator wheel train 29, 30 that operates the chronograph minute hand 12a, and a coil 41 for the timepiece mechanism.
The coil winding portions of the chronograph coil 45 and the chronograph coil 45 do not overlap in plane, and the chronograph coil 45 is formed to be smaller than the clock mechanism coil 41, and has a drive cycle shorter than that of the timepiece drive step motor. An analog chronograph crystal watch, characterized in that it is equipped with a timer 60 that stops a chronograph step motor drive signal having a short effective value and a small effective value after a predetermined period of time.
