* 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 or caseback.
CAUTION
① A 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.
② A 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.
③ A 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.
④ Keep 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.
⑤ Do not operate the crown underwater, or while the watch is wet. Water may enter the interior of the watch and defeat the water resistance.
⑥ If 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.
⑦ Even 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.
⑧ With 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.
⑨ The 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.
(2) Shock
① Be 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.
② Avoid a violent shock such as dropping the watch on the floor.
(3) Magnetism

② The 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.

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.
(11) Precautions when diving

Watches with “DIVER’S 200m” or “DIVER’S WATCH 200m” marked on its dial or case back are designed to be able to be used when scuba diving (air diving, water depth of up to 200m).
- This watch is not designed for saturation diving. Do not use this watch when saturation diving.
- Do not use this watch in water depths of 200m or deeper.

[Precautions before diving]

(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.

(3) Drive system: Mainspring Winding (Hand-winding)
(4) Running time : At least 50 hours
The stated daily accuracy is in the following conditions:
• After 24 hours at room temperature with the mainspring wound fully and the dial facing up.
- Due to the characteristics of the automatic winding watch, the time may deviate from the stated “daily accuracy” depending on the following conditions: amount of time the watch is worn each day, position of the watch, movement of your arm, winding condition of the mainspring.
- Determine the deviation from not just a day but a period of about a week.
Product specifications may change without notice, for improvement.

♦ 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.

◆ POWER RESERVE INDICATOR
The power reserve indicator shows how much the watch is wound, allowing you to see how much longer the watch will run at a glance. The time pointed to by the power reserve hand is the remaining time. When the power reserve hand indicates the 50 or F mark, the mainspring is fully wound.

natural_image

* The remaining time shown is only an approximation. The time shown may be different from actual remaining time.
This product is also equipped with an automatic winding function. When it is worn on the wrist, the movement of the arm will wind the mainspring.
The amount that the mainspring is wound will depend on the movement of the arm.
If you do not wind, the power reserve hand will move toward zero as time passes.
◆ 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.

◆ HOW TO USE THE INTERNAL ROTATING INDICATOR RING
Please notice that some models come with an internal rotating indicator ring, which should be used properly.
Turn the crown for the internal rotating indicator ring to set the ▽ - mark to the position of the minute hand.
The position of the internal rotating indicator ring to which the minute hand is pointing after some time has elapsed indicates the elapsed time.
Setting the mark to the desired time also allows you to know the remaining time.
