HOW TO USE
How to wind the mainspring
This watch is a self-winding watch equipped with a manual winding mechanism.
When the watch is worn on the wrist, the motion of the wearer’s arm winds the mainspring of the watch.
When first using a stopped watch, it is recommended that you manually wind the mainspring by turning
the crown.
Guide for winding state of the mainspring
Self-winding : The mainspring of the watch becomes fully wound when the watch is worn
for twelve hours per day for three to five consecutive days.
Manual-winding : It is possible to wind up for appropriately 10 hours by rotating the crown 5
times.
Observe the power reserve indicator to check the winding state of the mainspring.
* “Power reserve indicator” → P. 15
* This watch is configured in such a way that the mainspring cannot be over-wound.
Even if you turn the crown after the mainspring is fully wound, the mainspring will not wind up any more. Even if
you continue to turn the crown, it will not damage the watch, however, please refrain from operating the crown
excessively.
*
Under a low-temperature condition (below 0 ), please keep at least one-sixth of the watch power shown by the power
reserve indicator. There are possibilities that the watch may stop.

BEFORE USE
How to wind the mainspring by using crown (Hand winding)

* “Power reserve indicator” → P. 15

to lock the crown after operating it.
* When setting the time and date after winding,

BEFORE USE
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 stored enough power 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 continuous operating time of the watch may vary depending on the conditions of your usage (such as the
number of hours you wear the watch or the extent of your movement while wearing it).
* 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.
