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.)

* The continuous operating time of the watch may vary depending on the condition of use,
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, observe the power reserve
indicator to check the level of the remaining power. If necessary, manually wind the
mainspring.

The watch either stops
or is running down.
* This watch is configured so that the spring cannot be over-wound.
Once the mainspring is fully wound, the mainspring slips inside, disengaging the winding
mechanism. When this happens, you can still turn the crown without damaging the watch,
however, please refrain from excessive operation of the mainspring.

HOW TO USE Power reserve indicator
HOW TO USE
How to wind the mainspring
○ This watch is an automatic winding type (with manual winding function).
○ The mainspring can be sufficiently wound automatically by natural movement of the arm
while normally worn on the wrist. In addition, it can be wound by turning the crown.
Please see the power reserve indicator to check the level of the remaining power.
“How to read the power reserve indicator”→ P. 16
○ When starting to use a stopped watch, it is recommended that you turn the crown to wind
the mainspring. To wind the mainspring, unscrew the crown and turn it at the normal
position clockwise (12 o’clock direction) slowly. If you turn the crown counterclockwise
(6 o’clock direction), it will turn free. Six full rotations of the crown will provide the power to
run the watch for approximately ten hours.
“Screw down crown”→ P. 15
○ If you wear the watch for twelve hours per day consecutively for five to eight days, the watch
will be fully wound.
* Under a low-temperature condition (below 0°C), always keep at least one-fifth of the watch
power shown by the power reserve indicator.

○ Do not adjust the date when the time the watch indicates is between 9:00 p.m. and
1:00 a.m.
If the date is adjusted in this condition, the date may not change properly the following day,
or a malfunction may occur.
○ If you set the date when the time the watch indicates is between 9:00 p.m. and 1:00 a.m.,
pull out the crown to the second click, and turn it counterclockwise (6 o’clock direction) to
advance the hour hand until it passes 1:00 a.m. temporarily, and then set the date.
How to set the time and date
This watch is equipped with the date display function. The date changes once every 24 hours
at around midnight.
Therefore, if the a.m./p.m. is incorrectly set, the date will change around 12:00 p.m.
