<Notes on generating power and power reserve amount>
l
Number of swings and power reserve
• W
hen the power reserve in the rechargeable battery is depleted and the watch stops
completely, swing the watch for a few seconds at a rate of 2 to 3 times a second, and then check
if the direct drive indicator hand moves to the 0 position from the standby position. After the
direct drive indicator hand returns to the 0 position, charge the watch either by manual winding
or by swinging the watch, observing the movement of the direct drive indicator hand.
•
I
f the direct drive indicator hand remains moving at 2-second intervals, swing the watch
approximately 500 times at a rate of 2 to 3 times a second. By doing so, the direct drive
indicator hand will start moving at 1-second intervals.
If the
direct drive indicator hand still remains moving at 2-second intervals after this, continue
swinging the watch further until the second hand starts moving at 1-second intervals.
*
After the direct drive indicator hand resumes its 1-second-interval movement, if no
further power is generated subsequently, the watch will stop operating within three
minutes. While the direct drive indicator hand is moving at 2-second intervals, and no
further power is generated, the watch will stop operating within one minute.
l
Number of crown turnings and power reserve
• T
urning the crown 60 times within approximately one minute will generate the power reserve of
approximately 6 hours.
* The
amount of power generated by manual winding varies depending on the manner
in which you turn the crown, such as the speed or the length of strokes of turning the
crown.
