regulations are not strictly observed.

Precautions for diving

(Please make sure to observe the following.)

 CAUTION
If there are any malfunctions, contact the retailer from whom the watch was purchased
or SEIKO CUSTOMER SERVICE CENTER.

■ While diving

■ After diving

Please follow the care instructions below after diving.

Rinse the watch in fresh water to wash out all seawater and wipe it thoroughly dry to prevent rust. Avoid pouring running water onto the watch directly from a faucet. Put some water into a bowl first, and then soak the watch in the water to wash it.

  CAUTION
Depending on the environment where a diver’s watch is used, its inner parts or movement as well as its case or band may be affected. We recommend that you have your watch overhauled regularly once every 2 or 3 years.

■ Structure of the case
In the following types of models, take care of the following issues in usage. The bezel or protective outer case is securely fastened to the watch with setscrews. Never loosen the setscrews.

• The above illustration is provided as an example, therefore it may not be exactly the same as your watch.

CAUTION
Never loosen the setscrews used to fix the bezel or protective outer case.
Doing so may cause damage or result in further loosening.

• If you find that the setscrews have become loose or are functioning abnormally, consult the retailer from whom the watch was purchased or SEIKO CUSTOMER SERVICE CENTER.

Mechanical watch characteristics

(Hand-wound, auto-wound)

• This is a mechanical watch powered by a spring.
• To use it from a stopped state, turn the crown 20 turns by hand to wind up the spring before starting the watch.
• Although the accuracy of quartz watches is measured in differences over months or years, in mechanical watches it is measured in differences per day (i.e., the amount the watch speeds up or slows down in a single day).
• Additionally, mechanical watches are subtly affected by the conditions in which they are used (e.g., duration worn, temperature, arm movement, the amount wound, etc.) ; thus, the amount of error is not constant.
• When affected by a strong magnetism from outside, a mechanical watch may lose/gain time temporarily. The parts of the watch may become magnetized depending on the extent of the effect. In such a case, consult the retailer from whom the watch was purchased since the watch requires repair including demagnetizing.

Names of the parts and their functions

Screw down crown

The screw down crown features a mechanism that can securely lock the crown when it is not
being operated in order to prevent any operational errors and to improve its water resistant
performance.

• It is necessary to unlock the screw down crown before operating it.
• Once you have finished operating the crown, make sure to relock it.

• When locking the crown, turn it slowly with care, ensuring that the screw is properly engaged. Be careful not to push it in forcefully, as doing so may damage the screw hole in the case.

How to wind the mainspring

• This is an automatic mechanical watch with a manual winding mechanism.
• When the watch is worn on the wrist, the mainspring is wound automatically through normal wrist movement. The watch can also be wound up by turning the crown.
• To start the watch after it stops completely, wind it up either by turning the crown or swinging it from side to side until the seconds hand starts moving. Then, set the time and date before putting the watch on the wrist. To wind up the watch, unscrew the crown by turning it counterclockwise, and then, turn it clockwise slowly. The watch cannot be wound by turning the crown counterclockwise. In this way, the watch can be wound up fully. Furthermore, turning the crown further will not break the spring.
• Once the watch is wound up fully, it operates for about 70 hours.
• If the watch is used without being wound up fully, gain or loss of time may result. To avoid this, wear the watch for more than 10 hours a day. If the watch is used without being worn on the wrist, be sure to wind it up fully every day at a fixed time.
• If you use a watch that has stopped with the mainspring unwound, winding the mainspring with the crown will not start the watch immediately. That is because the mainspring torque or force is low at the beginning of its winding due to the characteristics of mechanical watches. The seconds hand will start to move when a certain degree of torque is reached after the mainspring has been wound up. However, swinging the watch from side to side to
  forcibly turn the balance can start the watch sooner.

How to set the time and date

The watch is provided with a date function and is so designed that the date changes once every
24 hours. The date changes around 12 o’clock midnight. If AM/PM is not properly set, the date will change at 12 o’clock noon.

CAUTION
Do not set the date between 9:00 p.m. and 1:00 a.m.
Amending the date during this time period may cause problems such as the date failing to change the next day.

CAUTION
The mechanism of mechanical watches is different from that of quartz watches. When setting the time, be sure to turn back the minute hand a little behind the desired time and then advance it to the exact time.

■ Date adjustment at the end of the month
It is necessary to adjust the date at the end of February and 30-day months.

Ex.) To adjust the date in the A.M. period on the first day of a month following a 30-day month
The watch displays “31” instead of “1.” Pull out the crown to the first click.

Turn the crown counterclockwise to set the date to “1” and then push the crown back in to the normal position.

CAUTION

• Return the screw down crown fully to its original position.
• Avoid amending the date when the watch is displaying between 9 PM and 1 AM. Doing so may cause damage.

How to use the rotating bezel

By setting the rotating bezel beforehand, the elapsed time since the start of an event can be measured.

• The above illustration is provided as an example, therefore it may not be exactly the same as your watch.

[One-Way rotating bezel]
As the evaluation of the remaining air in your cylinder is based on the information of the elapsed time of the dive, the rotating bezel for a diver’s watch is designed to rotate only counterclockwise, so that the watch is prevented from displaying the elapsed time shorter than it actually is.

CAUTION
Make sure that you check the correct remaining amount of air in your cylinder before diving.
Use the display of the elapsed time by the rotating bezel only as a guide during diving.

Daily care

● The watch requires good daily care

• Do not wash the watch when its crown is in the extended position.
• Wipe away moisture, sweat or dirt with a soft cloth.
• After soaking the watch in seawater, be sure to wash the watch in clean pure water and wipe it dry carefully.

Do not pour running water directly from a faucet onto the watch. Put some water into a bowl first, and then soak the watch in the water to wash it.

• If your watch is rated as “Non-water resistant” or “water resistant for everyday life”, do not wash the watch.

“Performance and type” → P. 26

● Turn the crown from time to time

• In order to prevent corrosion of the crown, turn the crown from time to time.
• The same practice should be applied to a screw down crown.

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, if 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.
  materials such as radioactive substances.

Magnetic resistant performance

Magnetic resistant performance
Affected by nearby magnetism,
a watch may temporarily gain or lose time or stop operating.
Diver’s watches feature magnetic resistant performance which is equivalent to or above JIS Class 1.

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 balance spring may be influenced by a strong external magnetic field.

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 titan 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.

● 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.

● Silicone band

• As for material characteristics, the band is easily dirtied, and may be stained and discolored.
  Wipe off dirt with a wet 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.

How to use the diver adjuster

If your watch’s metallic band has the Diver Adjuster function, the length of the band can be easily adjusted.

It is very useful when you wear the watch over a wet suit or winter clothing.

How to use the diver extender

If your watch’s metallic band has the Diver Extender function, the length of the band can be easily adjusted.

It is very useful when you wear the watch over a wet suit or winter clothing.

After sales service

● 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.
  Read carefully and retain it.

• 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 2 to 3 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 due to contamination of oil may advance or delay the time significantly, or the watch itself may 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.

CAUTION
Depending on the environment where a diver’s watch is used, its inner parts or movement
as well as its case or band may be affected. We recommend that you have your watch
overhauled regularly once every 2 or 3 years.

Accuracy of mechanical watches

• The accuracy of mechanical watches is indicated by the “daily
• The accuracy of mechanical watches may not fall within the specified range of time accuracy because loss/gain changes according to the position of the watch, which is dependent on the conditions of use, such as the length of time during which the watch is worn on the wrist, arm movement, and whether the mainspring is wound up fully or not, etc.
• The loss/gain of mechanical watches is not measured by a daily rate, but by daily rates of one week or so.
• Accuracy variation according to temperature

The parts that compose the accuracy of mechanical watches are made of metals. It is well known that metals expand or contract depending on temperatures due to metal properties. This exerts an effect on the accuracy of the watches. Mechanical watches tend to lose time at high temperatures while they tend to gain time at low temperatures.

○ Mainspring wound condition and accuracy
In order to improve accuracy, it is important to regularly supply energy to the balance that controls the speed of the gears. The driving force of the mainspring that powers mechanical watches varies between when fully wound and immediately before it is unwound. As the mainspring unwinds, the force weakens.
Relatively steady accuracy can be obtained by wearing the watch on the wrist frequently for the self-winding type and winding up the mainspring fully everyday at a fixed time to move it regularly for the wind-up mechanical type.

○ Effect of magnetism
When affected by a strong magnetism from outside, the mechanical watch may lose/gain time temporarily. The parts of the watch may become magnetized depending on the extent of the effect. In such a case, consult the retailer from whom the watch was purchased since the watch requires repair including demagnetizing.

Troubleshooting

• For a solution to a problem other than listed above, contact the retailer from whom the watch was purchased.

Specifications

• The accuracy above is factory-adjusted.
• Due to the characteristics of mechanical watches, any actual daily rate may not fall within the range of time accuracy specified above dependent on the conditions of use, such as the length of time during which the watch is worn on the wrist, temperature, arm movement, and whether the mainspring is wound up fully or not, etc.
