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.
[ For your information ]
1.
Number of swings and power reserve
·
When the watch stops completely, swinging it approximately 400 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, indicating that approximately one day of power has been reserved.
If the second hand still moves at two-second intervals after 400 swings, swing the watch further until
it moves at one-second intervals.
·
While the second hand is moving at one-second intervals, 350 to 400 swings will reserve up to one
day of power.
2.
Power reserve indication and duration of charge until the watch stops operating
·
Cal. 3M62A is equipped with a power reserve indicator. The current power reserve can be checked
using the second hand at the press of the power reserve indicator button.
Note: Immediately after the watch is charged by swinging it from side to side, the indicator may show
power reserve larger than the actual one. In that case, leave the watch untouched for 10 to 15
minutes, and then, check the power reserve.
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.
If the voltage obtained has increased more than 0.04 V from the initial voltage assuming that the initial
voltage is within the range between 0.5 V and 1.0 V, the automatic generating system is operating
normally.
