so, set the minute hand a few minutes
behind the correct time, and then slowly
advance it to the desired time.
※ Only the 24-hour and minute hands are to be set first.
Even if the hour hand is indicating incorrect time, or the
date may be altered depending on the position of the hour
hand, it is not necessary to make an adjustment at this
stage.

■HOW TO WIND THE MAINSPRING

This watch is a self-winding watch equipped with a manual winding mechanism. When
the watch is worn on the wrist, the motion of the wearer's arm winds the mainspring
of the watch.
When first using a stopped watch, it is recommended that you manually wind the
mainspring by turning the crown.
●Guide for winding state of the mainspring
Self-winding: ：
The mainspring of the watch is designed to be fully wound when it is worn for twelve hours per day
for three to five consecutive days.
Manual winding:
Five full rotations of the crown will provide the power to run the watch for approximately ten
hours.
Observe the power reserve indicator to check the level of the remaining power.
Refer to "POWER RESERVE INDICATOR" on page 55.
※ The watch employs a device to prevent overwinding of the mainspring. Once the mainspring is fully
wound, the mainspring slips inside, disengaging the winding mechanism. When this happens, you can
still turn the crown without damaging the watch, however, please refrain from excessive operation of the
mainspring.
※ Under a low-temperature condition (below 0℃), always keep at least one-sixth of the watch power shown
by the power reserve indicator.

■POWER RESERVE INDICATOR

The power reserve indicator lets you know the winding state of the main-
spring.
Before removing the watch from your wrist,
observe the power reserve indicator to
check if the watch has stored enough power
to keep running until the next time you wear
it. If necessary, wind the mainspring. (To
prevent the watch from stopping, wind the
mainspring to store the excess power that
will allow the watch to run for extra time.)
※ The continuous operable time of the watch may vary depending on actual use conditions, such as
the number of hours you wear the watch or the extent of your movement while wearing it.
※ In a case where you wear the watch for a short period of time, observe the power reserve indica-
tor to check the level of the remaining power. If necessary, manually wind the mainspring.

■HOW TO SET THE TIME AND CALENDAR

To set the time and calendar, set the 24-hour hand and minute hand first,
and then set the hour hand and calendar.
●How to set the time
1. Make sure that the mainspring is sufficiently wound and the watch is working.
※ When setting the date and time, ensure that the watch is working.
2. Unlock the crown.
Refer to "How to use the screw lock type
crown" on page 52.
3. Pull out the crown to the second click
when the second hand is pointing at
the " 0 " second position. The small
second hand will stop on the spot.
Second hand is pointing at
the " 0 " second position.
7. Turn the crown to set the hour hand.
While turning the crown, the moment the
date changes is midnight. When setting
the hour hand, be sure that AM/PM is set
correctly.
Adjust the calendar also at this point
if necessary.
※ The crown can be turned in either direction
to adjust the date, however, it is recommend-
ed to turn the crown in the direction which
enables you to set the date with a smaller
adjustment.
※ Turn the crown slowly, checking that the
hour hand moves in one-hour increments.
※ When adjusting the hour hand, the other
hands may move slightly. However, this is not
a malfunction.
8. Push the crow n back in to complete the time setting.
