![]() | ![]() | ![]() | ![]() | ![]() | ||
| Non water resistant | Watch without WATER RESIST-ANT on back cover of watchcase. | × | × | × | × | × |
| Water resistant for daily life | Watch with WATER RESISTANT on back cover of watchcase. | ○ | × | × | × | × |
| Reinforced water resistance for daily life I | Watch with 50M (5BAR) on back cover or dial face along with WATER RESISTANT on back cover of watchcase. | ○ | ○ | × | × | × |
| Reinforced water resistance for daily life II | Watch with 100M (10BAR), 150M (15BAR), 200M (20BAR) on back cover or dial face along with WATER RESISTANT on back cover of watchcase. | ○ | ○ | ○ | × | × |
* 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.
WARNING
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.
CAUTION
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
① If 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.
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 vi - brations such as from riding motorcycles, using jackham- mers, chain saws, etc.

natural_image

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.

Do not attempt to disassemble or modify this product.

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"
Some products 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.
◆ 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 “☐DJ02002B☐”, the caliber number is “DJ”.
2. Searching by the case code
See the case code on the case back of your watch.
The first two digits indicate the caliber number.

◆ AUTOMATIC WINDING AND HAND WINDING MECHANISM
(1) This is an automatic winding (hand winding) mechanical watch.
(2) The mainspring is wound by natural movements of your arm when wearing the watch on your wrist.
It is also wound by rotating the crown.
(3) If your watch stops, winding the mainspring by rotating the crown or swing the watch back and forth ten or more times to re-start the second hand. After it starts moving, set the date and time.
(4) To wind the mainspring, ensure that the crown is in its normal position and slowly turn it to the right (clockwise).
Turning the crown to the left (counterclockwise) will have no effect.
When the watch is in a stopped state, the mainspring can be wound sufficiently by rotating the crown approximately 20 times. In order to the crown will still rotate even when the mainspring is fully wound. (This is not a fault). Avoid winding the watch more than necessary.
Since the crown will rotate even when winding is complete, wind the watch using the scale on the power reserve indicator as a guide.
(5) This watch will run approximately 40 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 (dual time), first turn the crown to the left to loosen the screw lock.
(2) After setting the date and time (dual time), turn the crown to the right while pressing in, until it stops turning to securely tighten the screw.

natural_image
Illustration of a hand holding a wristwatch with an arrow indicating rotational motion (no text or symbols)◆ MODELS WITH A SCREWED-DOWN BUTTON RING \*EJ (40G) only
Depending on the product, some models may have a configuration that allows the button ring (ring on the outer periphery) to be locked (fixed) into place by being screwed down.
Use the following operating method for this type of watch.
- When wanting to use the buttons, first turn the button ring to the left, and then loosen it until the screw stops.
* The buttons may not be able to be used if the button ring cannot be loosened enough. Do not turn it more forcefully than necessary. - After finishing using the buttons, turn the button ring to the right, and firmly tighten it until the screw stops.
* Do not tighten it more forcefully than necessary.
◆ 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.
The remaining time shown is only an approximation. The time shown may be different from actual remaining time.

text_image
Technical diagram of a wristwatch with hand and dial indicators, showing front and back views and measurement markings.Power reserve hand
This product has an automatic-winding system which comes with a power reserve indicator function. The mainspring will be automatically wound by your natural arm movements while you wear it on your wrist. The power reserve hand is pointing to the fully-wound position (40H). The amount the watch is wound will change with the frequency of your arm movements and the length of time you wear the watch, so the hand will not always point to the fully wound position. If you remove the watch from your arm and do not wind manually, the power reserve hand will move toward zero as time passes.
◆ HOW TO SET THE TIME [ DE(40A), DJ(40P), EL(40N)]
(1) Pull out the crown to the second click when the second hand reaches the 12 o'clock position.
(The second hand will stop.)
(2) Turn the crown clockwise and set the current time.
* Since this watch comes with a calendar, make sure that you set either a.m. or p.m. without fail. The date changes at [twelve o'clock midnight].
* When setting the time, first bring the hand back slightly later the actual time and then move it forward to the actual time.
(3) Press the crown in to the normal position.

◆ USING THE ROTATING INDICATOR BEZEL
Please notice that some models come with a rotating indicator bezel, which should be used properly.
Turn the bezel 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 bezel. 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 bezel reversely since it comes with a protection mechanism for preventing wrong operation by force or shock. Figures on the bezel could also help you to read the current time easily.
