HOW TO USE
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 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 operating time of the watch may vary depending on the condition of use,
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
indicator to check the level of the remaining power. If necessary, manually wind the
mainspring.

* This watch is configured so that the spring cannot be over-wound.
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.
