Abstract

PURPOSE: To enable control of stator position with respect to a rotor in an electronic watch in a simple construction by providing a circular hole at the substrate of a drive unit and the stator and a long groove communicating concentrically with the circular hole thereat and inserting an eccentric driver into the hole and groove.
CONSTITUTION: A circular hole 10 is perforated at a substrate 3, and a long groove 11 communicating concentrically with the hole 10 and having larger width than the diameter of the hole 10 is provided at the stator 2 of an electronic watch. An independent eccentric driver 12 of a plurality of cylinders with parallel error between the axes thereof is inserted between both the hole 10 and the groove 11 to thereby control the stator position with respect to a rotor 1. Thus, it eliminates the step of assembling another eccentric pin thereto and provides simple construction of the drive unit.
