■ 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 your arm automatically winds the mainspring of the watch.
※ Observe the power reserve indicator to check the amount of the remaining power.
⇒ ■ "POWER RESERVE INDICATOR" page 53
※ When first using the 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.
CAUTION
※ 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.

■ POWER RESERVE INDICATOR

The power reserve indicator lets you know the winding state of the mainspring
（the amount of the remaining power） .
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.）
Power reserve indicator
※ 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 each day, observe the power reserve
indicator to check the level of the remaining power. If necessary, manually wind the mainspring.
