* It is recommended that you use the watch correctly following the above-mentioned scope of usage
after ascertaining water resistance precautions marked on the dial face of the watch or on the back
of the watchcase.

ENGLISH
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.
CAUTION

WARNING

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.
CAUTION

ENGLISH
(7) About accessory parts
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
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”
This watch has 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.

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 10-digit model number
Check the 10-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 second
and third digits indicate the caliber number of your watch.
Example: If the model number is “CUB8A002B0”, the caliber number is “UB”.
2. Searching by the case code
See the case code on the case back of your watch.
A: If the case code is 6 digits, the first two digits indicate the caliber number.
B: If the case code is 8 or 9 digits, the first three digits indicate the movement
number. Search the caliber number corresponding to the movement
number referring to the correspondence table.
Example A Example B
Case code Case code
Example A : When the case code is “UB8A-Q0”, the caliber number is “UB”.
Example B : When the case code is “HM50A7B-4”, the movement number
is “HM5”. The caliber number corresponding the number will be
found “UB” on the table.
* 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.

position of 0 second (12 o’clock), pull out
the crown.
The second hand will stop.
*When your watch was only two hands,
pull out the crown any time because it
does not have the second hand.
(2) Turn the crown to set the time.
To set the time accurately, advance the
minute hand four or five minutes ahead
of the correct time, then move it back to
the correct time.
(3) Press the crown in to the normal
position.

USING THE ROTATING INDICATOR RING
Please notice that some models come with a rotating indicator ring, which
should be used properly.
Turn the ring by pointing the
V mark to the
minute-hand. While certain time goes by, you
can measure the elapsed time from the distance
between minute-hand and figures on the rotating
indicator ring. You can also set the
V mark as a
desired time to remind you how long time is still
remain for an appointment.
You cannot turn the ring reversely since it comes
with a protection mechanism for preventing
wrong operation by force or shock. Figures on
the ring could also help you to read the current time easily.
* Depending on design, anti-reversely and 1 minute “click” sound mechanism
on rotating indicator ring does not apply to some models.
