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 Winding state of the mainspring Fully wound Half wound Unwound Number of hours the watch can run Approximately 72 hours (3 days) Approximately The watch either stops 36 hours (1.5 days) or is running down. * The position or design of the displays may differ depending on the model. 20 * 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 mechanism, 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. 21 English
