Requests and Cautions Regarding this Watch
(Mechanical Watch with Auto-Winding Function)
* Although the mainspring will be wound automatically when the watch is
worn on the wrist, the mainspring will wind down aer about 2 days and
the watch will stop if it is removed from the wrist.
* Make sure to adequately wind the mainspring before setting the time (hour
and minute hands).
* If the time is set without the mainspring being adequately wound, the
second will oscillate back and forth 2-3 seconds.
ere are two ways to wind the mainspring: winding by turning the
crown to the right by hand, and winding by shaking the watch gently. e
second hand may rarely oscillate back and forth if the mainspring has
been wound by shaking the watch to the side with excessive force
However, this has no eect on the functions or performance of the watch.
Even if the crown is turned further aer the mainspring is fully wound,
there will be no damage caused to the mainspring.
<Adjusting the metal band or other parts of the watch>
Do not attempt to adjust the metal band by yourself. Doing so may result
in damage to the watch through dropping it, or injury to yourself from the
repair tools. Please contact your dealer or Customer Support Center for
adjustment of the metal band; otherwise, adjustment may not be possible or
may not be free of charge.

1. Features
Self-Winding Movement
• A self-winding movement is employed in which the watch mainspring is
wound automatically by movement of the hand when worn, and the force
of the mainspring is then used to drive the movement (watch).
Automatic winding
When worn on the wrist, the normal movement of the arm will wind the spring. Please
make sure to wear it for at least 8 hours daily. In case most of your work is at a desk and
there is little arm movement, it may result in insucient winding. In such cases, please
wind manually.
Manual winding
Rotate the crown clockwise in position 0 to wind the spring.
If the watch has stopped, rotating the crown around 40 times will result in sucient
winding of the spring.
When fully wound, further rotating the crown will not damage the spring.

3. Before Using
is watch is a mechanical watch (self-winding). Before using, disengage the screw
down locking crown and turn it to the right by hand to wind the watch mainspring.
When the mainspring is in the fully wound state (suciently wound), the watch will
continue to run for about 40 hours. In order to ensure that the watch continuously
provides a stable time display, always wear the watch on your wrist to keep the
mainspring adequately wound. If the watch is only worn for short periods of time,
wind the mainspring manually by turning the crown by hand.
Note:
A screw down locking crown is employed to
enhance the water resistance of the watch.
When operating the crown, rst turn it to the
le to disengage the screw lock. Once you have
nished operating the crown, always make sure
to return the crown to the normal position and
then turn it to the right while pushing it in so
that the screw lock is securely engaged.
[General Reference for Winding Mainspring when Completely Unwound]
• Aer rst loosening the screw down locking crown, turn it to the right
about 40 revolutions to fully wind the mainspring.
Keep the mainspring adequately wound either by turning the crown by hand or
by wearing the watch on your wrist for at least three hours each day.
If the watch is only worn for short periods of time, turn the crown by
hand to keep the mainspring fully wound. Since this watch employs a
slip mechanism that automatically disengages the mainspring when fully
wound, it cannot be over-wound.

• is date displayed by this watch is based on a 31-day month. e date
must be changed by operating the crown on the rst day of the following
month in those months with less than 31 days (months having 30 days and
February).
5. Using the Rotating Bezel
e rotating bezel can be used as a reference for elapsed time during diving or
for the amount of time remaining relative to a predetermined amount of time.
[Setting the Rotating Bezel]
•Only turn the rotating bezel to the le. It cannot be rotated in the
opposite direction (to the right) to prevent the risk of incorrect operation.

After a certain amount
of time has elapsed, the
elapsed time can be
determined from the

CAUTION To avoid injury
• Be particularly careful when wearing your watch while holding a small child, to
avoid injury.
• Be particularly careful when engaged in strenuous exercise or work, to avoid injury
to yourself and others.
• Do NOT wear your watch while in a sauna or other location where your watch may
become excessively hot, since there is the risk of burns.
• Be careful when putting on and taking o your watch, since there is a risk of
damaging your ngernails, depending on the manner in which the band is fastened.
CAUTION Precautions
• Always use the watch with the crown pushed in (normal position). If the crown is
of the screw lock-type, make sure it is securely locked.
• Do NOT operate the crown when the watch is wet. Water may penetrate into the
watch, causing deterioration of water resistance.
• If water enters the watch or the watch fogs up and does not clear up even aer a
long time, consult your dealer or Customer Support Center for inspection and/or
repair.
• If a watch of upgraded water resistance for daily use is immersed in sea water or
subjected to excessive perspiration, thoroughly rinse with fresh water and wipe
completely dry with a so cloth.
• If seawater enters the watch, place the watch in a box or plastic bag and immediately
take it in for repair. Otherwise, pressure inside the watch will increase, and parts
(crystal, crown, buttons, etc.) may come o.
