HOW TO READ THE POWER RESERVE INDICATOR
•
The power reserve indicator lets you know the winding state of the mainspring.
•
Before removing the watch from your wrist, observe the power reserve indicator
to check if the watch has enough power stored 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.)

When the mainspring is fully wound, the crown can be turned further, or the
mainspring may wind without damaging the mainspring itself. The mainspring of
the watch employs a slipping mechanism, an automatic watch specific mecha-
nism, to prevent the mainspring from overwinding.
● Remarks on the automatic mechanism of the mainspring
The mainspring of the watch becomes fully wound when it is worn for twelve hours
for three to five consecutive days. However, the winding state of the mainspring 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. It is recommended that you
observe the power reserve indicator to check the level of remaining power of your
watch.
*
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.
