How to wind the mainspring
Manual winding type (the procedure below is the same
when you wind up an automatic winding type by hand)
1 Do not pull the crown out.
(If the watch is equipped with the screw down crown, unscrew the crown before pulling it
out.)
2 Slowly turn the crown clockwise to
wind the mainspring.
* When the mainspring approaches full-winding, turning of the crown is heavy more or
less, however, this is caused by reaction force of the wound mainspring, which is not
defective.
* It is structured so that the crown can be further turned in the full-winding state. Although
it is not necessary to worry about cutting the mainspring, refrain from excessive turning.
(2L, 4S, 6L, 6S, 4L and 8L series)
3 Please wind the mainspring fully everyday at a fixed time to keep the watch moving
accurately.
b CAUTION
In case of 68 series watches that have thin movement, it becomes harder to turn the crown
when the mainspring is fully wound up.
Be careful not to keep turning the crown forcibly. Otherwise the mainspring may be cut.
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 adjust the time and date.
* 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.
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.)
