Notes
✽ If there is any time difference between the factory default time settings and the local time
in your area, reset the time and calendar before initially using the watch after purchase.
✽ While the watch is in power save mode, the built-in IC computes the time internally at an
accuracy of ± 15 seconds per month which is equivalent to the accuracy of conventional
quartz watches. Therefore, the time relayed from the built-in IC to the hands by the
automatic time relay function may include a certain amount of time loss or gain within the
range of the accuracy of the watch (
±15 seconds per month.) In such a case, reset the time
as needed before starting to wear the watch.
✽ When the watch wakes up from power save mode while it is running on extremely low
electrical power, the second hand starts moving at two-second intervals. (Refer to “ IF THE
SECOND HAND STARTS MOVING AT TWO-SECOND INTERVALS“ on page 17. )
HOW TO WAKE UP THE WATCH FROM POWER SAVE MODE
● In order to “wake up” the watch from power save mode, swing the watch gently
from side to side to recharge it.
✽ Do not pull out the crown to the second click position before performing the following
procedures. This will cancel the time relay function.
Swing the watch from side to side approximately 4 to 6 times rhythmically at
a rate of twice a second, making an arc of about 20 cm as shown in the
illustration below.
✽ No additional benefit is obtained by swinging the watch with
greater vigor.
✽ When the watch is swung, the oscillating weight in the generating
system rotates to drive the mechanism. As it rotates, it gives out
a sound, which is not a malfunction.
1. Only the hour, minute and 24-
hour hands move quickly to indi-
cate the current time which has
been internally retained in the
built-in IC.
2. Then the second hand will follow
quickly to resume the normal
movement.
The second hand
remains still.
