How to read the power reserve indicator

1
･ 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.)
