* 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.

* The position of the crown may vary on some models.

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 time, first turn the crown to the left to loosen the screw

lock.

(2) After setting the time, turn the crown to the right while pressing in, until it

stops turning to securely tighten the screw.

ENGLISH



HOW TO SET THE TIME

(1) When the second hand comes to a

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.

Turn

Counterclockwise

Turn Clockwise

ENGLISH

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

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

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.
