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.
○ A stopped watch can be started by arm movement when it is worn on the wrist, however,
before wearing the watch, wind the mainspring sufficiently and set the time and date. When
winding the mainspring, turn the crown at the normal position clockwise (12 o’clock
direction) slowly. If you turn the crown counterclockwise (6 o’clock direction), it will turn
free.
The mainspring is sufficiently wound when the crown is turned approximately 60 times.
When the mainspring is in the full-winding state, it is designed so that the mainspring slips
if it is overwound. Therefore, it is not necessary to worry about breaking the mainspring,
however, please refrain from excessive operation.
* It is recommended that you wear the watch on your wrist more than 10 hours a day to keep
the mainspring wound up. If the mainspring is not wound up sufficiently, the watch may
lose or gain time. If you use the watch without wearing on your wrist, wind the mainspring
up sufficiently by turning the crown by hand every day at a fixed time.

CAUTION
○ 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 set during this period of time, the date may not change when the next day
comes, or this may cause damage.
○ If the time you want to set is between 7:00 p.m. and 1:00 a.m., first return the time to 6:00 p.m.,
and then turn the crown counterclockwise (6 o’clock direction) so the hands advance in the
clockwise direction to set the time.
○ Due to its gear train mechanism, for setting the time of the mechanical watch correctly, the
hands should be set back once slightly and then set forward to the correct time.
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.
