ENGLISH
CAUTION
!
1A watch with water resistance for daily life 30m (3 bar) can be used
during face-washing, etc. but cannot be used in an environment in which
it will be submerged in water.
2A watch with reinforced water resistance for daily life I 50m (5 bar) can be
used while swimming, etc. but cannot be used during any type of diving
including skin diving.
3A watch with reinforced water resistance for daily life II 100m or 200m (10
or 20 bar) can be used while skin diving, but cannot be used while scuba
diving using oxygen tanks or saturation diving using helium gas, etc.
4Keep the crown pushed in at all times (in the normal position) while using
the watch. If the crown is the screwed-down type, check that it is securely
screwed down.
5Do not operate the crown underwater, or while the watch is wet. Water
may enter the interior of the watch and defeat the water resistance.
6If your watch is non-water resistant, beware of splashes of water (during
face washing, rain, etc.) and sweat. If the watch becomes wet from water
or sweat, wipe the moisture off with a dry, soft cloth.
7Even with a water resistant watch for everyday use, avoid directing
strong jets of mains water onto the watch. Water pressure above the limit
can apply, which may defeat the water resistance.
8With a water resistant watch for everyday use, rinse sea water off the case
after exposure, then wipe it thoroughly to avoid corrosion and other effects.
9The interior of the watch contains some amount of moisture, which may
cause fogging on the inside of the glass when the outside air is cooler
than the internal temperature of the watch. If the fogging is temporary
it causes no harm inside the watch, but if prolonged, or if water enters
the watch, consult your place of purchase and do not leave the problem
untreated.

ENGLISH
(2) Shock
1Be sure not to carry the watch when you engage in
strenuous sports, whereas playing such light sports as golf,
etc., will not adversely influence the watch.
2Avoid a violent shock such as dropping the watch on the
floor.
(3)Magnetism
1If the watch is left at a location with strong magnetism for an extended
period of time, the components may be magnetized, resulting in
malfunction. Be careful.
2The watch may temporarily speed up or slow down when exposed to
magnetism. Precision is restored when placed away from magnetism. In
such a case, reset the time.
(4)Vibration
The watch may lose precision if subjected to strong
vibrations such as from riding motorcycles, using
jackhammers, chain saws, etc.
(5)Temperature
In environments below and above normal temperatures (5°C-35°C), the
watch may malfunction and stop.
Do not use the watch at high temperatures, such as in a sauna. The
watch may heat and cause burns.
(6)Chemicals, Gases, etc.
Utmost caution must be exercised when coming into contact with gases,
mercury, chemicals (paint thinner, gasoline, various solvents, detergents
containing such components, adhesives, paint, drugs, perfumes,
cosmetics, etc.), and so forth. Such may cause discoloration of the
watchcase, watchband, and dial face. Discoloration, deformation, and
damage to various resin-based component parts may also occur.

(7) About accessory parts
CAUTION
!
Do not attempt to disassemble or modify this product.
WARNING
!
Store the bracelet/strap pin and other small parts out of the reach of
children.
If any small parts are swallowed, immediately contact a doctor.
(8)Allergic reactions
CAUTION
!
If you develop a skin rash or your skin becomes abnormally irritated due
to contact with the watch or strap, stop wearing the watch immediately
and consult a doctor.
(9)About “luminous light”
Some watch have luminous light on the hands and dial.
The luminous light is a safe paint that stores sunlight and artificial light
without using any radioactive material, and emits that light in a dark
setting. As the paint discharges the stored light, it will become dimmer
over time. The amount of light emitted and the time that light is emitted
depends on various factors when the light is stored, such as the shape
of the glass, the thickness of the paint, surrounding brightness level, the
distance from the watch to the light source, and the light absorption level.
Please note that when not enough light energy is stored, the watch may
emit weak light or emit light for only a short time.
(10)Water resistant watchband
Some products employ leather and nylon bands on which a special
treatment to resist perspiration and water absorption have been applied.
Please understand that the water resisting effect of this watchband can
be lost depending on the period and conditions of use.

• To remove salt water from the case or bracelet/strap, first make sure
the crown is securely tightened. Then, rinse it with fresh water to
prevent rusting.
• Do not use chemical agents to rinse the watch or soak the watch.
(12)Changing the interchangeable watchband
Depending on the model, some watches come with interchangeable
watchbands.
Please contact your dealer or our service center if you want to change
the watchband.
◆HOW TO IDENTIFY THE CALIBER NUMBER
Check the caliber number by referring to the model number of your watch or
the case code on the watch’s case back.
1. Searching by 13-digit model number
Check the 13-digit model number on the guarantee supplied with your watch.
You can also see the number on the product tag put on the watch. Its fourth
and fifth digits indicate the caliber number of your watch.
Example: If the model number is “RE-AT0001L00B”, the caliber number is “AT”.
2. Searching by the case code
See the case code on the case back of your watch like XXXX-XXXX.
The first three digits indicate the caliber number.
Example : When the case code is “F6R4-UAA0”, the caliber number is “F6R”.
* The place of case code may vary and its letter size may be small and
difficult to see depending on the characteristics of watches.
* The pictures and illustrations on this manual may differ from the actual
appearance of your watch but the function and operation procedures are
the same.

◆ 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.
