Abstract: A mechanism having at least a function of measuring an arbitrary elapsed time is provided, which disables the function from being reset after the function is started, and enables the function to be reset after the function is stopped. The function is continuously held in an electrical ON state after being started, except when being normally stopped. This provides a time measurement device and method in which an electrical operating state and a mechanical operating state can coincide.

Abstract: 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.

Abstract: An electronic timepiece without system failure at the time of transfer from the power-saving mode to the display mode is provided. A power-saving control circuit 400 controls drive of a date dial displaying a date when updating a date display, which has been stopped in a power-saving mode, to a current date at the time of transfer from the power-saving mode to the display mode. The power-saving control circuit 400 outputs a date dial drive inhibiting signal, which prohibits drive of the date dial 75, to a date-updating control circuit 300, if a voltage VDD of a power source unit B is less than or equal to a low threshold voltage V1. It outputs a date dial deceleration driving signal, which drives a date dial 75 with a predetermined speed slower than a normal update speed when transferring to the display mode, to a date-updating control circuit 300, if a source voltage VDD is equal to or less than a high threshold voltage V2.

Abstract: In a time measurement device (1000) having, at least, both a function of measuring standard time and a function of measuring any elapsed time, when a predetermined amount of time passes from a temporary suspension of a watch hand in position in the middle of the measurement of the elapsed time, the suspension of the watch hand is automatically released and the watch hand is driven to a watch hand position indicating the elapsed time. Provided thereby is the time measurement device which automatically releases the temporary suspension state in time measurement after the predetermined amount of time, thereby shortening the temporary suspension time and reducing power consumed to drive the watch hand to an originally expected watch hand position at the release of the temporary suspension.
