◆ AUTOMATIC AND HAND WINDING MECHANISM
(1) This is an automatic winding mechanical watch (with a
hand winding mechanism).
(2) The mainspring is wound by natural movements of your
arm when wearing the watch on your wrist.
In addition, you can also wind the mainspring by turning
the crown.
(3) If your watch stops, either swing the watch back and forth
ten or more times or turn the crown to wind the mainspring in order to
restart the second hand.
After it starts moving, set the calendar and time.
(4) When winding the mainspring, slowly turn the crown to the right
(clockwise) while in its normal position.
Turning the crown to the left (counterclockwise) merely turns the crown
uselessly and does not wind the mainspring.
You can wind the mainspring fully by turning the crown to the right about
30 times from a stopped position.
The crown can still be turned after the mainspring is fully wound. Either
use the above count or use the markings on the power reserve indicator
when winding the watch.
(5) Even if the mainspring is fully wound, it will not be over-wound due to the
slip mechanism.
(6) This watch will run approximately 50 hours after it is fully wound. If it is
not wound enough, the watch may lose accuracy. In order to maintain the
watch's accuracy, we recommend wearing the watch at least 8 hours a day.
 MODELS WITH SCREWED-DOWN CROWN
Depending on the model, you may not be able to pull the crown out without
unscrewing it (models with screwed-down crown).
Operate this type of watch as follows:
(1) Before setting the date and time, first turn the crown counterclockwise to
loosen the screw lock.
(2) After setting the date and time, turn the crown clockwise while pressing
in, until it stops turning to securely tighten the screw.
