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.)
