Please enable office standard frequency is no called with a "1" mark summer time in the time zone can be as by receiving the frequency, if the time zone is within the radio signal reception range.

There are time differences around the world based on "Coordinated Universal Time (UTC)." There are 24 regions (Time Zones) around the world with a time difference of one hour. This system has been adopted internationally by setting the total time difference around the world as 24 hours. In addition, Daylight Saving Time (Summer Time) is individually adopted in some regions.

[What is UTC (Coordinated Universal Time)?]

UTC is the universal standard time coordinated through international agreement. It is used as the official time around the world. UTC is determined by adding a leap second to GMT (Greenwich Mean Time), which is determined through astronomical measurement, in order to keep the precise time.

[What is summer time (DST)?]

Summer time is daylight saving time. Advancing the watch one hour to prolong daytime during longer daylight hours in summer. Daylight saving time has been adopted in about 80 countries, mainly in Europe and North America. The adoption and duration of daylight saving time vary depending on the country.

※ Time differences between regions and daylight saving time may change due to circumstances of a country or region. ※ A time difference established in 15 minute or 30 minute units is adopted in very limited regions (ex. India). ※ Each indication may differ depending on the model (design) of the watch. (As of April 2014)

About charging

How to charge the watch

To enjoy optimal performance of this watch, make sure that the watch is kept sufficiently charged at all times.

Illustration of a wristwatch with a sun icon projecting the light (no text or symbols)

To charge the watch, expose the dial (solar cell) to adequate light.

* When changing the watch, keep the watch temperature under 60°C * Before initially using the watch or when the watch has stopped as a result of complete depletion of stored power, charge the watch sufficiently.

If the watch is concealed under a long sleeve shirt, or if it is used or stored continually under conditions where it cannot receive sufficient light, the power stored in the solar cell may be easily depleted because the watch cannot be sufficiently charged.

★ The figures in the table above refer to the time required to charge the stopped watch by exposure to light until the watch moves at steady one-second intervals. Even if the watch is partially charged for a period shorter than the time provided in the above table, it will resume one-second interval movement; however, the one-second interval movement will change to two-second interval movement shortly. To avoid this and charge the watch to a sufficient level, use the charging time mentioned above as a measure.

The required charging time slightly varies depending on the model of the watch The movement of the second hand checking the charging status → page 92

About energy

■ Energy depletion forewarning function

The energy depletion forewarning function is activated when the energy stored in the watch runs low. In such a case, the second hand moves at two-second intervals. If the watch continues to be in the state of two-second interval movement, the watch switches to five-second interval movement, followed by a completely stopped state. If the energy depletion forewarning function is activated, charge the watch sufficiently.

How to charge the watch… page 110

Standard charging time ....page 111

* Neither the buttons nor the crown can be operated while the second hand moves at two-second or five-second intervals (this is not a malfunction):
※ While the second hand moves at five-second intervals, the hour and minute hands, date and day stop operating.
* While the second hand moves at five-second intervals, the watch is unable to receive radio signals automatically. After the watch is charged sufficiently and the second hand returns to normal one-second interval movement, conduct the manual reception of radio signals to set the watch to the correct time. (Refer to 'How to set the time, date and day' on page 95.)

Power save function

This watch is equipped with a power save function (Power Saving) which can suppress energy consumption when it is left without receiving an adequate light source for a certain length of time.

	Power Save 1	Power Save 2
Condition	When the watch is exposed to a state without receiving an adequate light source for 72 hours or longer.	When the watch is in an insufficient charging state for a long time.
Situation

Power Save 2
※ While the watch is being charged, the second hand moves at "Five-second Intervals."
During the "Five-second Interval Movement," neither the buttons nor the crown can be operated.
If the "Power Save 2" mode is probable, the secret power amount drops and the internal current time information stored will be lost. When the watch returns to its normal movement of one-second interval after sufficiently charging the battery, set the current time by receiving a radio signal (Refer to Setting the time and date by receiving a radio signal + page 95).

To preserve the quality of your watch

Daily care

• The watch requires good daily care

• Wipe away moisture, sweat or dirt with a soft cloth
• To clean the clearances (around the metallic band, crown or case back), a soft toothbrush is convenient.
  • After soaking the watch in seawater, be sure to wash the watch in clean pure water and wipe it dry carefully.

• 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 lock type crown.
(No need to pull out the screw lock type crown.)

116 117

WARNING

Do not use the watch in scuba diving or saturation diving.

The various tightened inspections under simulated harsh environment, which are usually required for watches designed for scuba diving or saturation diving, have not been conducted on the water-resistant watch with the BAR (barometric pressure) display. For diving, use special watches for diving.

CAUTION

※ If the inner surface of the glass is clouded with condensation or water droplets appear inside of the watch for a long time, the water resistant performance of the watch is deteriorated. Immediately consult the retailer from whom the watch was purchased or SEIKO CUSTOMER SERVICE CENTER (listed on the end of a book).

Do not turn or pull out the crown when the watch is wet.

Water may get inside of the watch.

CAUTION

Do not leave moisture, sweat and dirt on the watch for a long time.

Be aware of a risk that a water resistant watch may lessen its water resistant performance because of deterioration of the adhesive on the glass or gasket, or the development of rust on stainless steel.

Do not wear the watch while taking a bath or a sauna.

Steam, soap or some components of a hot spring may accelerate the deterioration of water resistant performance of the watch.

Do not pour running water directly from faucet.

The water pressure of tap water from a faucet is high enough to degrade the water resistant performance of a water resistant watch for everyday life.

■ Magnetic resistance

Affected by nearby magnetism,

a quartz watch may temporarily gain or lose time or stop operating. When the hand positions deviate to display incorrect time as a result of influence of magnetism, this watch automatically corrects the hand alignment itself. (Refer to page 142)

Indication on the case back	Condition of use
No indication	Keep the watch more than 10 cm away from magnetic products.
	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)

Examples of common magnetic products that may affect watches

Cellular phone (speaker)

Magnetic health belt

Bag (with magnet buckle)

Magnetic necklace

AC-powered shaver

Magnetic health mat

Portable radio (speaker)

Magnetic health pillow

Magnetic cooking device etc

The reason why analogue quartz watch is affected by magnetism.

It is because the built-in motor of the watch, which harnesses magnetic power and external strong magnetism, affect each other to stop the motor or suppresses the turn of the motor.

120

121

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, sweet or soil will cause rust even on a stainless steel band if they are left for a long time.
• Lack of care may 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.)
• Because some titan bracelets 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 bracelet, 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 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 or cracked, replace the band with a new one.

Notes on skin irritation and allergy	Skin irritation caused by a band has various reasons 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.

Lumibrite

If your watch has Lumibrite

Lumicrite is a luminous paint that is completely harmless to human beings and natural environment, containing no noxious materials such as radioactive substance.

Lumbrite is a newly-developed luminous paint that absorbs the light energy of the sunlight and lighting apparatus 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, Lumbrite can emit light for 3 to 5 hours. Please note, however, that, as Lumbrite 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 according 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.

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	1,000 lux
	Distance to the watch: 3 m	500 lx (average room unitance)

③ Do not move the watch while receiving a radio signal.

The reception of a radio signal cannot be conducted unless the watch is still.

It takes 12 minutes at the longest according to the receiving state of a radio signal.

After about one minute from the start of receiving a radio signal, the second hand will start to indicate the receiving level.

Display during reception

Receiving Level is High: The second hand points to H (High, the 50 second position)

Receiving Level is Low: The second hand points to L (Low, the 40 second position)

Reception level is updated by moving the second hand every one minute. ※ The minute hand moves by one minute along with the movement of the second hand.

4 The watch displays the time when receiving a radio signal and after receiving a signal.

▶ Check whether the receiving a radio signal has been successful. → page 102
During the movement of the date, neither the buttons nor the crown can be operated.

Not receivable

After five seconds, the watch will resume displaying the time.

※ It is difficult to receive the signals in some receiving conditions. → Environments in which it is difficult to receive a radio signal indication on page 103 ※ This watch is unable to receive a radio signal outside a reception range → Radio signal reception range on pages 96-98 ※ When the watch is unable to receive radio signals → If the Reception has failed: The second hand points to N on page 103.

Conditions in which the watch may be unable to receive radio signals

How to manually set the time

When the watch is used continuously in conditions in which the watch may be unable to receive a radio signal, it can be manually adjusted.

※ When the watch is unable to receive a radio sign, it can move depending on normal quartz movement (accuracy of loss / gain: ±15 seconds per month).
- When adjusting the time, the date will be accordingly adjusted. - When the watch receives a radio signal after manual adjustment of the time, it displays the received time. - When using the watch again in regions in which the watch is able to receive a radio signal, it is recommended to perform "Manual reception." → How to conduct manual reception on pages 136-137

1 Pulling the crown to the second click

The Second hand moves to point to the 'Zero second' position and the watch enters the manual time setting mode.

When the watch enters the manual time setting mode, the reception results will be indicated as "N," since the reception results data will be lost.
