发明名称 Pointer electronic timepiece, operating method and control program thereof
摘要 A pointer electronic timepiece (1) has a plurality of step motors, a plurality of pointers (11 to 18), and a plurality of external operation members of a winding crown (5) and buttons (6, 7). The pointer to be adjusted is selected from the plurality of pointers (15 to 18) by operating one of the buttons (6) while drawing out the winding crown (5) to a second stage and the other button (7) is operated to adjust the position of the selected pointer. Since the position of the pointers (15 to 18) driven by three step motors can be adjusted by the two buttons (6, 7), the number of the external operation member is not necessary to be increased even when the pointers (15 to 18), i.e. the step motors, are increased, so that the size and thickness of a movement-holder and cost thereof can be reduced and operability during adjustment can be improved.
