PROHIBITED Do not use this watch while diving when...
• Do not use your watch while diving when the watch stops or exhibits any abnormal operation.
CAUTION Diving with the watch
• Persons using the diver’s watch are strongly recommended to receive proper instruction and
training pertaining to diving and observe those rules at all times.
• Please use this watch properly only after you fully understand the operating procedures and
cautions.
Using this watch other than as indicated in this instruction manual may result in failure of the
watch to function properly.
• Check the water-resistant indications on the watch face or the case back. Never dive beyond
the indicated depth.

English
CAUTION Before diving
• Check items below before diving
- Make sure that the watch is fully wound.
- Make sure that the watch is running correctly (check the movements of the time/calendar/
second hand)
- Make sure that the crown is pushed all the way in and locked in place.
- Make sure that the band is firmly anchored to the watch body.
- Make sure that there are no cracks or other damage to the watch band or the glass face.
- Make sure that the register ring rotates properly.
CAUTION During diving
• During diving, never operate the crown. Operating any of them in water may cause trouble
including deterioration of water resistance.
• Be careful not to hit the watch against hard objects such as equipment or rocks.
CAUTION After diving
• After making sure that the crown is locked in place, make sure the watch is free of seawater,
mud and sand using fresh water. Wipe completely with a dry cloth.

Characteristics of Mechanical watches
About time accuracy of mechanical watches
The time accuracy described on this instruction manual is the static accuracy
at normal temperature. The accuracy of mechanical watches may get out of the
described range depending on the following three usage conditions or other
reasons.
• Winding amount of the mainspring
• Attitude
• Usage environment (temperature, magnetism, impact, etc.)
Winding amount of the mainspring
Mechanical watches keep accuracy most stably when the mainspring is sufficiently
wound.
Attitude
Accuracy of mechanical watches varies affected by gravity. The accuracy varies
as the result that may take various attitude while worn and gravitate to a different
direction every moment.

8
Characteristics of Mechanical watches
Usage environment (temperature, magnetism, impact, etc.)
• Metal parts are used for the part for keeping accuracy in mechanical watch. The
accuracy varies affected by their thermal expansion and contraction.
• Metal parts are used in mechanical watches. Magnetism affects them and
accuracy of the watches in consequence. Do not bring them close to things which
have or generate strong magnetism.
• Strong shocks may also affect the accuracy.
Maintenance
Mechanical watches may become inaccurate due to insufficient lubrication or worn
parts. Have the watch disassembled and cleaned (overhaul) every 2-3 years (charge
basis). It may be difficult to restore the watch from degradation after long-term use
to its initial performance even after repairs.

English
■Water-resistant to 200m
• This watch is a scuba diver’s watch (water-resistant to 200m). You can use it
for scuba diving with air tanks, but must not be used in a helium-enriched
atmosphere (e.g. saturation diving).
■Automatic winding movement
• A automatic 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 mainspring.
[Manual winding]
Rotate the crown clockwise while it is in position to wind the mainspring.

Band adjustment
We recommend seeking the assistance of an experienced watch technician
for sizing of your watch. If adjustment is not done correctly, the bracelet may
unexpectedly become detached leading to loss of your watch or injury.
Consult an authorized service center.
Protective stickers
Be sure to remove any protective stickers that may be on your watch (case back,
band, clasp, etc.). Otherwise, perspiration or moisture may enter the gaps between
the protective stickers and the parts, which may result in a skin rash and/or
corrosion of the metal parts.

Before using
How to use a specially designed crown
Unlock the crown prior to operate your watch.
Unlock Lock
Screw down
crown
Rotate the crown
counterclockwise until
it releases from the
case.
Push the crown in to the
case. With gentle pressure
towards the case, rotate the
crown clockwise to secure
it to the case. Be sure to
tighten firmly.

Requests and cautions regarding this watch
(Mechanical watch with automatic winding function)
• Although the mainspring will be wound automatically when the watch is worn on
the wrist, the mainspring will wind down after 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 hand
will oscillate back and forth 2-3 seconds.
There are two ways to wind the mainspring: winding by turning the crown to the
right by hand, and winding by shaking the watch gently. The 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 effect on the functions or performance of the watch.

Mainspring
Note:
A screw down locking crown is employed to enhance the water resistance of the
watch. When operating the crown, first turn it to the left to disengage the screw
lock. Once you have finished 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.
This watch runs using the power of the mainspring.
• Once the mainspring is wound fully, it will run for about 40 hours.
• Sufficient winding ensures stable and accurate movement.
About winding the mainspring
This watch is an automatic winding mechanical watch. (You can also wind the
mainspring manually.) The mainspring is wound by swinging your arm. It is
recommended to wear the watch for more than 8 hours a day. If you do not move
your arms much in your daily life, for example you spend a lot of time sitting at
a desk, the mainspring may not be wound sufficiently. In such cases, wind the
mainspring manually.

Mainspring
Winding the mainspring manually
Turn the crown to the right (clockwise) in position .
• When the watch stops, turning the crown about 40 times will wind the
mainspring fully.
• When the mainspring is wound fully, turning the crown further does not damage
the mainspring.

English
Setting the time and calendar
• Avoid correction of the date and day when the watch hands are between the hours
of 9:00 PM and 4:30 AM. Correcting the date and day during this time period
may prevent the date from changing on the following day. Set the date and day
after the hands have moved outside this time period.
• The date displayed by this watch is based on a 31-day month.Re-set the correct
date at the start of March, May, July, October and December.
