How to wind the mainspring
This watch is a self-winding watch equipped with a manual winding mechanism.
- When the watch is worn on the wrist, the motion of the wearer's arm winds the mainspring of the watch.
- When first using a stopped watch, it is recommended that you manually wind the mainspring by turning the crown.
■ Guide for winding state of the mainspring
Self-winding: The mainspring of the watch becomes fully wound when the watch is worn for twelve hours per day for three to five consecutive days.
Manual-winding: It is possible to wind up for appropriately 10 hours by rotating the crown 5
times.
Observe the power reserve indicator to check the winding state of the mainspring.
* "Power reserve indicator" → P. 15
* This watch is configured in such a way that the mainspring cannot be over-wound.
Even if you turn the crown after the mainspring is tully wound, the mainspring will not wind up any more. Even if you continue to turn the crown, it will not damage the watch, however, please refrain from operating the crown excessively.
* Under a low-temperature condition (below 0 °C), please keep at least one-sixth of the watch power shown by the power reserve indicator. There are possibilities that the watch may stop.
EN 13
■ How to wind the mainspring by using crown (Hand winding)
1 With extra care so as not to press the crown in, slowly turn it in the direction of the arrow.

* There are time zone differences around the world based on time offsets from Coordinated Universal Time (UTC). The world is divided into 24 time zones where each part has a time difference of one hour. This system is adopted internationally in such a way that one full rotation of the earth corresponds to 24 hours (one day).
Depending on the country or the region, daylight saving time (summer time) is adopted individually.
* Daylight saving time, being defined as time difference +1 hour, is a system that advances the time by 1 hour during summer time to prolong the daylight hours.
* Time difference and daylight saving time are subject to change depending on the conditions of the respective countries or regions.

(The direction and the amount to turn the rotating bezel can be determined by the following method. [The direction and the amount to turn the rotating bezel] E
is calculated as,
[Time difference from UTC of 24-hour hand, C] - [Time difference from UTC of the region you wish to know, D]
E=C-D
In this example, the 24-hour hand indicates Japan time, and therefore, C = +9.
a) As an example, If the time of a region you wish to know belongs to the time zone of UTC, the time difference from UTC is "0" and hence.
D=0
UTC can be read as "1:00" on the rotating bezel scale.
* If E is a positive number *-, turn the rotating bezel clockwise. If it is a negative number *-, turn it counter clockwise.
b) As another example, if you wish to know the time of the region "Los Angeles", the time difference from UTC is "-8 hours", so D = -8 E = C - D = (+9) - (-8) = +17
Turn the rotating bezel 17 hours clockwise (Result: Same as the counter clockwise rotation of 7 hours)
Los Angeles time can be read as "17:00". * When this intended usage is no longer needed, please return the original position "24" mark of rotating bezel to 12 hour position.
* "List of time zone differences in major regions of the world" • P. 33
EN 38
■ In the case of 24-hour hand being set to different time zone
Three different time zones can be read by turning the rotating bezel.
[Example] When displaying 10:08 AM Japan time with the hour and minute hands, and displaying Paris time with the 24-hour hand.
Time difference from UTC of "Paris" where the 24-hour hand is set, C = +1
Time difference from UTC of "Bangkok" that you wish know from now on, D = +7 E=C-D= (+1) - (+7) = -6
Turn the rotating bezel counterclockwise and set.

"CROWN"→P.12
Lumibrite
If your watch has Lumibrite
Lumibrite is a luminous paint that absorbs the light energy of sunlight and lighting apparatuses in a short time and stores it to emit light in the dark. For example, it exposed to a light of more than 500 lux for approximately 10 minutes. Lumibrite can emit light for 3 to 5 hours. Please note, however, that, as Lumibrite emits the light it stores, the luminance level of the light decreases gradually over time. The duration of the emitted light may also differ slightly depending on such factors as the brightness of the place where the watch is exposed to light and the distance from the light source to the watch.
In general, when coming from a place that is bright to a place that is dark, it takes human eyes some time to adapt to the darkness making it difficult to see objects initially. (Dark adaptation)
* Lumibrite is luminous paint that stores and emits light, which is harmless to human beings and the environment, containing no toxic materials such as radioactive substances.
| Condition Illumination | ||
| Sunlight | Fine weather 100,000 lux | |
| Cloudy weather 10,000 lux | ||
| Indoor (Window-side during daytime) | Fine weather more than 3,000 lux | |
| Cloudy weather 1,000 to 3,000 lux | ||
| Rainy weather less than 1,000 lux | ||
| Lighting apparatus (40-watt daylight fluorescent light) | Distance to the watch: 1 m 1000 lux | |
| Distance to the watch: 3 m 500 lux (average room luminance) | ||

| Keep the watch more than 5 cm away from magnetic products.(JIS level-1 standard) | |
| Keep the watch more than 1 cm away from magnetic products.(JIS level-2 standard) | |
If the watch becomes magnetized and its accuracy deteriorates to an extent exceeding the specified rate under normal use, the watch needs to be demagnetized. In this case, you will be charged for demagnetization and accuracy readjustment even if it happens within the guarantee period.
The reason why a watch is affected by magnetism
The built-in regulating mechanism is provided with a magnet, which may be influenced by a strong external magnetic field.
EN 44
Band
The band touches the skin directly and becomes dirty with sweat or dust. Therefore, lack of care may accelerate deterioration of the band or cause skin irritation or stain on the sleeve edge. The watch requires a lot of attention for long usage.
Metallic band
- Moisture, sweat or soil will cause rust even on a stainless steel band if they are left for a long time.
- Lack of care may result in a rash or cause a yellowish or gold stain on the lower sleeve edge of shirts.
- Wipe off moisture, sweat or soil with a soft cloth as soon as possible.
• To clean the soil around the joint gaps of the band, wipe it out in water and then brush it off with a soft toothbrush.
(Protect the watch body from water splashes by wrapping it up in plastic wrap etc.)
Clean it off with a soft cloth. - Because some titanium bands use pins made of stainless steel, which has outstanding strength, rust may form in the stainless steel parts.
- If rust advances, pins may poke out or drop out, and the watch case may fall off the band, or the clasp may not open.
- If a pin is poking out, personal injury may result. In such a case, refrain from using the watch and request repair.

● Leather band
- A leather band is susceptible to discoloration and deterioration from moisture, sweat and direct sunlight.
- Wipe off moisture and sweat as soon as possible by gently blotting them up with a dry cloth.
- Do not expose the watch to direct sunlight for a long time.
- Please take care when wearing a watch with light-colored band, as dirt is likely to show up.
- Refrain from wearing a leather band watch other than Aqua Free bands while bathing, swimming, and when working with water even if the watch itself is water resistant enforced for daily use (10-BAR/20-BAR water resistant).
● Polyurethane band
- A polyurethane band is susceptible to discoloration from light, and may be deteriorated by solvent or atmospheric humidity.
- Especially a translucent, white, or pale colored band easily adsorbs other colors, resulting in color smears or discoloration.
- Wash out dirt in water and clean it off with a dry cloth.
(Protect the watch body from water splashes by wrapping it up in plastic wrap etc.) - When the band becomes less flexible, have the band replaced with a new one. If you continue to use the band as it is, the band may develop cracks or become brittle over time.
EN 47
Silicone band
- As for material characteristics, the band is easily dirtied, and may be stained and discolored. Wipe off dirt with a wel cloth or cleaning tissue.
- Unlike bands of other materials, cracks may result in the band being cut. Take care not to damage the band with an edged tool.
| Notes on skin irritation and allergy | Skin irritation caused by a band may result from various factors such as allergy to metals or leathers, or skin reactions against friction on dust or the band itself. |
| Notes on the length of the band | Adjust the band to allow a little clearance with your wrist to ensure proper airflow.When wearing the watch, leave enough room to insert a finger between the band and your wrist. |  |

Notes on guarantee and repair
- Contact the retailer from whom the watch was purchased or SEIKO CUSTOMER SERVICE CENTER for repair or overhaul.
- Within the guarantee period, present the certificate of guarantee to receive repair services.
- Guarantee coverage is provided in the certificate of guarantee.
• For repair services after the guarantee period has expired, if the functions of the watch can be restored by repair work, we will undertake repair services upon request and payment.
● Replacement with functional parts
- Please keep in mind that if original parts are not available, they may be replaced with substitutes whose outward appearance may differ from the originals.
● Inspection and adjustment by disassembly and cleaning (overhaul)
- Periodic Inspection and adjustment by disassembly and cleaning (overhaul) is recommended approximately once every 3 to 4 years in order to maintain optimal performance of the watch for a long time.
- The power transmission gear of the movement of this watch constantly receives force. To ensure that this mechanism works properly all the time, washing parts, changing oil, adjusting accuracy, checking functions and replacing consumable parts on a regular basis are important. The first overhaul after the purchase of your watch is particularly important for preserving long-time use of your watch. According to use conditions, the oil retaining condition of your watch mechanical parts may deteriorate, abrasion of the parts may occur due to contamination of oil, which may ultimately lead the watch itself to stop. As the parts such as gasket may deteriorate, water resistant performance may be impaired due to intrusion of perspiration and moisture. Inspection and adjustment by disassembly and cleaning (overhaul) should be performed by the retailer from whom the watch was purchased, and who specifies "SEIKO GENUINE PARTS." At this time, also request replacement of the gasket and the spring bar.
- When your watch is inspected and adjusted by disassembly and cleaning (overhauled), the movement of your watch may be replaced.
