English 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.) Power Reserve Indicator The winding state of the mainspring The number of hours the watch can run 12 Fully wound Approximately 41 hours 1/2 wound Approximately 20 hours Unwound The watch either stops or is running down * When the mainspring is fully wound, the crown can be turned further without damaging the mainspring itself. The mainspring of the watch employs a slipping mechanism to prevent the mainspring from overwinding. * The orientation of "the power reserve indicator" may slightly vary depending on the model. * Power reserve indication is intended only as a guide. Thus, the power reserve indicator may or may not be right over / after the "E" when the watch stops. 13 English
