HOW TO SET THE TIME AND CALENDAR
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.
In a case that the watch is completely stopped due to a shortage of stored
electrical energy, recharge the watch until the second hand resumes the
normal one-second interval movement, and then reset the time and calen-
dar. (Refer to “IF THE SECOND HAND STARTS MOVING AT TWO-SECOND
INTERVALS” on page 19.)
HOW TO SET THE TIME
If your watch has a screw lock type
crown, unscrew the crown first, and
then pull it out to the second click.
To set the second hand exactly, pull
out the crown to the second click at a
moment the second hand is pointing to
the 12 o’clock (“0” second) position.
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 19. )
1. Pull out the crown to the second click.
The second hand will be stopping on
the spot.

To set the time accurately, advance
the minute hand 4 to 5 minutes ahead
of the correct time, and then turn it
back to the exact time.
3. Push the crown back into the original
position. The watch immediately starts
ticking.
To set the second hand exactly, push
the crown back into the original position
in accordance with a time signal.
