Claims (1)

[Claims for Utility Model Registration] An oscillator, a frequency dividing circuit that divides the signal from the oscillator and outputs a plurality of pulse train signals with different periods, a watch dial covered with a cover glass, and this watch. The touch switch group is divided into a plurality of regions, and each touch switch group is provided for each part of the cover glass that covers each region, and when all the touch switch groups are not operated, one
a fast-forward circuit that outputs a pulse train signal with a divided period and a pulse train signal with a shorter period than the pulse train signal when any one of the touch switches is turned on; a motor; and a pulse train signal output from the fast-forward circuit. a drive circuit that converts the pulse signal into a pulse signal that drives the motor, a wheel train driven by the motor, and hour and minute hands that drive the clock face by the wheel train and display the hours and minutes of the time. A timepiece comprising: an hour hand position detection circuit that counts pulse train signals from the fast forward circuit to detect in which area of the watch dial the hour hand is located; and which area of the touch switch group is located. a memory circuit that memorizes whether a touch switch located at the touch switch is operated and outputs a memory signal, and holds the memory signal until an area where the touch switch is located matches an area where the hour hand is detected by the hour hand position detection circuit; an initial reset circuit that outputs a reset signal for resetting the hour hand position detection circuit until the touch switch group is operated for the first time after the power is turned on; A pulse signal having a period is outputted, and when the touch switch group is operated, a first fast-forward signal having a period shorter than one minute is outputted from the frequency dividing circuit, and when a storage signal is outputted from the storage circuit. a switching gate circuit that outputs a second fast-forward signal having a shorter period than the first fast-forward signal from the frequency dividing circuit; and a switching gate circuit that outputs a second fast-forward signal having a shorter cycle than the first fast-forward signal; an initial fast-forward circuit that supplies a second fast-forward signal to the drive circuit and also supplies an output signal from the switching gate circuit to the drive circuit while the initial reset circuit is not outputting. A clock correction device.
