TECHNICAL GUIDE

Cal. 5J32A

2.Close the case back tentatively, and swing the watch

from side to side 200 times at a rate of 2 to 3 swings a second, making an arc of approximately 20 cm.

3. Within 3 minutes after swinging the watch, measure the voltage of the rechargeable battery in the same manner as in step “1” above.

4.Refer to the table below, and decide whether the automatic generating system is normal or defective.

[ Initial voltage and guidelines of normal/defective decision ]

	Initial voltage	Guidelines of normal/defective decision

	0.45 V ~ 1.0 V	After charging, the voltage of rechargeable battery has increased 0.1 V or
	0.45 V ~ 1.0 V	more from the initial voltage.
		more from the initial voltage.

	1.01 V ~ 1.2 V	After charging, the voltage of rechargeable battery has increased 0.05 V or
	1.01 V ~ 1.2 V	more from the initial voltage.
		more from the initial voltage.

*The guidelines specified in the above table apply only when the initial voltage is within the range between 0.45 V and 1.2 V.

*The amount of electricity generated by swinging the watch varies depending on the manner in which you swing it, such the rate of swinging and the size of the swinging arc. Please note, therefore, that checking through the procedure above provides only the guideline of normal/defective decision.

[ For your information ]

1.Number of swings and power reserve

·When the power reserve in the rechargeable battery is depleted and the watch stops completely, swinging it approximately 500 times at a rate of 2 to 3 times a second will start the second hand moving at normal one-second intervals instead of two-second intervals. If the second hand still moves at two-second intervals after 500 swings, swing the watch further until it moves at one- second intervals.

·While the second hand is moving at one-second intervals, approximately 200 swings will reserve up to one day of power.

2.The number of days over which the watch is worn and power reserve

·Wearing the watch continuously for 12 hours will accumulate approximately one and a half additional days of power reserve.

If you wear the watch every day for 12 hours over a period of a week, approximately 10 days of power reserve will be secured in the rechargeable battery. While the power saving function is in operation and the hands are stopped, this amount of power reserve will keep the watch operating for approximately 2 months.

●Checking the manual power save and time relay functions

Cal. 5J32A is equipped with the automatic and the manual power save functions to conserve the stored energy and the time relay function to start the hands moving to indicate the current time as the power save function is canceled.

Note: The checking procedure below can be performed only while the watch is operating. If the watch stops completely, swing the watch until the second hand starts moving at one-second intervals. Swing it further more than 200 times, and then, proceed to the checking procedure.
