ELECTRONIC TIMEPIECE

PROBLEM TO BE SOLVED: To adjust an electronic timepiece to prescribed time accuracy and to cause the accuracy to be maintained after a theoretical regulation pattern is cut off while keeping the regulation pattern from short-circuiting to another adjoining theoretical regulation pattern and to a bottom plate. SOLUTION: In this electronic timepiece, theoretical regulation patterns 42 to 46 formed on a circuit substrate 30 incorporated in a movement 10 are cut off to change the setting of a logical regulation circuit 86, thereby adjusting the time accuracy. This electronic timepiece is equipped with the bottom plate 20, the circuit substrate 30 incorporated in an upper surface of the bottom plate 20, a clearance hole 21 bored in the bottom plate 20, a theoretical regulation pattern cut-off hole 31 opened in the circuit substrate 30 and disposed in an upper part of the clearance hole 21, and cut-off parts (a) of the regulation patterns 42 to 46 provided in the area of the cut-off hole 31. The cut-off parts on the side connected to the regulation circuit 86 are provided at a distance keeping it from contacting with the clearance hole 21 in the bottom plate 20 and at a distance keeping it from contacting with another adjoining theoretical regulation pattern when the regulation patterns 42 to 46 are cut off.
