Manual winding type (the procedure below is the same when you wind up an automatic winding type by hand)
-
Do not pull the crown out.
-
Slowly turn the crown clockwise to wind the mainspring.
-
Please wind the mainspring fully everyday at a fixed time to keep the watch moving accurately.
(If the watch is equipped with the screw down crown, unscrew the crown before pulling it out.)
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)
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.
