English

* 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 over-winding.

* The orientation of “the power reserve indicator” may slightly vary depending on

the model.

● Remarks on the automatic mechanism of the mainspring

The correlation between the number of hours the watch is worn and the winding state

of the mainspring is provided below for your reference. 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.

The mainspring of the watch becomes fully wound when it is worn for twelve hours

for three to five consecutive days.

* 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.

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.)
