CAUTIONS

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

Water may get inside of the watch.



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 WORLDWIDE SERVICE NETWORK.

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 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 glas s or gasket, or the development of rust on stainless steel.

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.

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 per formance of a water resistant watch for everyday life.

Mechanism by which the GPS solar watch sets time and date

What GPS is

GPS stands for Global Positioning System, a satellite positioning system for determining the current position on the earth. 24 satellites cover the earth, and at present, the system is operated by approximately 30 GPS satellites. Wherever you are in the world, the position can be determined (positioned) by information from more than 4 GPS satellites.

Mechanism by which this watch sets the time

and date

This watch receives GPS signals from GPS satellites to set the time and date based on the following information.

GPS satellite

This is a satellite operated by the United States Department of Defense (official name is NAVSTAR), and orbits the earth at an altitude of 20,000 km. Initially, this was a military satellite, but at present, information is partially disclosed to the public and used in various equipment including car navigation systems and cellular phones. The GPS satellite is mounted with a high-accuracy atomic clock with an accuracy deviation of 1 second per 100,000 years.

• Precise time and date based on the atomic clock

• Information about a time zone where you are

(The current location is basically positioned by more

than 4 GPS satellites, and which zone of the total of 40 time zones around the world you are in is identified.)

 To receive information about a time zone where you

are, it is necessary to adjust the time zone.

 How to adjust the time zone P. 1 7

 Unlike navigation equipment, this GPS solar watch is

not designed to constantly receive GPS signals from GPS satellites without any operation.

This watch receives GPS signals from GPS satellites

only in the time zone adjustment mode, automatic or manual time adjustment mode.

Time zone

Based on Coordinated Universal Time (UTC), the standard time commonly used is adopted by countries and regions around the world. The standard time is determined by each country or region, and the region where the same standard time is adopted is referred to as the time zone, and presently, the time zone is divided into 40 zones.

DST (Daylight Saving Time)

Depending on the area, DST (Daylight Saving Time) is individually set. Daylight Saving Time means summer time, which is a system to lengthen daylight time by advancing 1 hour when daylight time is long 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.

 Daylight Saving Time is subject to change owing to circumstances of the country or region.



Set DST (Daylight Saving Time) P. 1 8

Coordinated Universal Time (UTC)

UTC is the universal standard time coordinated through an international agreement. This is used as the official time for recording time around the world. The time obtained by adding a leap second to the “International Atomic Time (TAI)” determined based on the atomic clock around the world and coordinated in order to compensate for deviations from universal time (UT) which is astronomically determined is the UTC.

 Each time zone is based on data as of January 2014.

 Please be advised that regions for which the time zone is changed thereafter cannot be

reflected.

 The time differences and use of daylight saving time in each city are subject to

change according to the governments of the respective countries or regions.

About charging

How to charge the watch

Expose the dial to light to charge the watch.

Under the following situations, the energy of the watch is likely to be depleted, resulting in stoppage of the watch.

• The watch is concealed under a sleeve.

• The watch is used or stored under conditions where it cannot be exposed to light for a long time.

To ensure optimal perf ormance of the watch, make sure that the watch is kept suf ficiently charged at all time.



When charging the watch, make sure that the watch is not heated to a high

temperature. (The operational temperature range is between –10 °C and +60 °C.)



When first using the watch or starting to use the watch after it has stopped

because of the energy depletion, sufficiently charge the watch referring to the table on the page at the right.

Standard Charging Time

For an approximate time required to charge the watch, refer to the table below.

GPS signal reception consumes a lot of energy. Keep in mind to charge the watch by expose to light so that the indicator hand points to the “level position (middle)” or “F (full).”

(If the charging status is displayed as “E (low),”

the reception will not start even with operation of GPS signal reception.)



Check the charging status. P.12



The required charging time slightly varies depending on the design and the dial color of the

watch.

The figures of “Time required for charging the watch to st art moving at one-sec ond intervals” are estimations of time required to charge the stopped watch by exposing it to light until it moves at steady one-second intervals. Even if the watch is par tially charged for a shorter period, the watch will resume one-second- interval movement. However, it may shortly return to t wo-second-inter val movement. Use the charging time in this column as a rough guide for sufficient char ging time.

Automatic time adjustment

This watch can be set to the precise current time by automatically receiving GPS signals by exposure to bright light outdoors under an open sky to adjust the time.

In addition, when the watch is concealed under a sleeve and the dial is not exposed to sufficient light even if outdoors under an open sky, the watch stores the time of the previous successful manual time adjustment (or time zone adjustment), and automatically starts time adjustment at the same time.

 In a place without good visibility, GPS signals cannot be received.  Place where GPS signals can be easily received/Place where GPS signals cannot be

received P. 1 5

 If the energy is sufficiently charged, automatic reception will be performed every day.  The automatic time adjustment is performed at most once per day. Therefore, even if automatic time adjustment has failed, the next automatic time

adjustment will be performed the next day or thereafter.

 The time zone is not adjusted in the automatic time adjustment. When the region where the watch is used is changed, please carry out time zone adjustment. How to adjust the time zone P. 1 7

When it is difficult to expose to light sufficiently

Even if outdoors under an open sky, when the watch is concealed under a sleeve in winter time, etc., in an area where the daylight hours are short, or when the watch is not likely to be exposed to sufficient light for a long time due to bad weather, the watch is designed to allow for automatic time reception at the time when the manual time adjustment was successful the last time. When the watch is exposed to the operating environment above, automatic time adjustment is likely to be successful by making manual time adjustment successful in time periods where the watch is frequently used in a place where GPS signals can be easily received under an open sky.

CONTENTS

GPS signal reception includes three types. Features for each type are as follows.

GPS signal reception Q & A

GPS signal reception

Q: When the watch is moved to a different time zone, does the

watch automatically display the local time?

A: The watch does not automatically display the local time just by

being moved. If you are in a place where GPS signals can be easily received, adjust the time zone. The watch automatically displays the local time.

When you are in a place where GPS signals cannot be received,

manually set the time zone.

 Manual time zone setting P. 2 1

The watch can be set to all time zones around the world.

Q: Is DST (Daylight Saving Time) automatically changed by

receiving GPS signals? A: Manually set DST (Daylight Saving Time).  Set DST (Daylight Saving Time) P. 1 8 (GPS signals from GPS satellites do not include information

about DST (Daylight Saving Time).) Even in the same time zone, some countries and regions do not

adopt DST (Daylight Saving Time).  DST (Daylight Saving Time) P. 11

Q: Is it necessary to carry out special operation for years in which a

leap second is added? A: No special operation is necessary. Since the watch receives leap second data at the same time of

receiving GPS signals on or after June 1st and December 1st,

a leap second is automatically added by periodically receiving

GPS signals. For details, refer to “Leap second (automatic leap

second reception function)  P. 26.”

Leap second (Automatic leap second reception function)

Receiving Leap Second Data

When the GPS signal reception is performed on or after December 1st and June 1st, the indicator hand displays as shown at the right.

When the leap second data reception is completed, the indicator hand returns to display the charging status. Use the watch as it is.

 The leap second data reception is performed every half a year regardless of leap second addition.

It takes up to 18 minutes to receive the leap second data.

Leap second

The leap second is to compensate for deviations from the universal time (UT) which is astronomically determined and the “International Atomic Time (TAI). “1 second” may be added (deleted) once a year or every few years.

Automatic leap second reception function

A leap second is automatically added by receiving “leap second data” from GPS signals at the time of leap second addition (delete).

 “Leap second data” includes information about future leap second addition and current

leap second data.

When GPS signals are received under the following conditions, the leap second data reception is also started.

• GPS signals are received after the system reset

• GPS signals have not been received for a long time

• Leap second data reception has failed

(Leap second data reception is performed again during the next GPS signal reception. It is repeated

until the leap second data reception is successful.)

Examples of common magnetic products that may affect watches

Magnetic resistance (Magnetic influence)

Keep the watch more than 5cm away from magnetic products.

If the watch becomes magnetized and its accuracy deteriorates to an extent exceeding the specified rate under normal use, there will be a charge for demagnetization and accuracy readjustment even if it occurs within the guarantee period.

The reason why this watch is affected by magnetism

The built-in motor is provided with a magnet, which may be influenced by a strong external magnetic field.

This watch may be affected by nearby magnetism and temporarily gain or lose time or stop operating.

 Even when the watch gains or loses time due to magnetic influence, the hand positions

are automatically adjusted by the “automatic hand position adjustment function.” (P. 44)

This watch has magnetic resistance which complies with ISO “Magnetic resistant watches”.

Band

Notes on the length of the band

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.

Adjust the band to allow a lit tle clearance with your wrist to ensure proper airflow. When wearing the watch, leave enough room to insert a finger bet ween the band and your wris t.

●

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 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/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.

●

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.

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.

If your watch has Lumibrite

Lumibrite is a luminous paint that is completely harmless to human beings and natural environment, containing no noxious materials such as radioactive substance. Lumibrite 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, 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 you enter a dark place from a bright environment, your eye cannot adapt to the change in light levels quickly. At first, you can hardly see anything,

but as time passes, your vision gradually improves. (Dark adaptation of the human eye)

Power Source

The battery used in this watch is a special secondary battery, which is different from ordinary batteries. Unlike an ordinary silver oxide battery, the secondary battery does not require periodic replacement.

The capacity or charging efficiency may gradually lower due to long-term use or operating environment. In addition, long-term use may shorten the charge duration due to wear, contamination, lubricant deterioration of mechanical parts, etc. Request repair when the performance lowers.

 Overcharge prevention function

When the secondary battery is fully charged, the overcharge prevention function is automatically activated to avoid further charging. There is no need to worry about damage caused by overcharging no matter how much the secondary battery is charged in excess of the "time required for fully charging the watch".

 Refer to "Standard charging time" on page 11 to check the time required for fully

charging the watch.

 When the watch has not been charged for a long time

If the watch has not been charged for a long time, the watch will be completely discharged and no longer able to be charged. In this case, consult the retailer from whom the watch was purchased.

WARNING

Notes on replacing the second battery

• Do not remove the secondary battery from the watch. Replacement of the secondary battery requires professional

knowledge and skill. Please ask the retailer from whom the watch was purchased for replacement of the secondary battery.

• Installation of an ordinary silver oxide battery can generate heat that can cause bursting and ignition.

Notes on charging the watch

• When charging the watch, do not place the watch in close proximity to an intense light source such as lighting equipment for photography, spotlights or incandescent lights, as the watch may be excessively heated resulting in damage to its internal parts.

• When charging the watch by exposure to direct sunlight, avoid places that easily reach high temperatures, such as a car dashboard.

• Always keep the watch temperature under 60°C.

Preliminary position

When the watch is unable to display the precise time or date, or any stopwatch hands or indicator hand does not point to the correct position even when it has successfully received GPS signals, the preliminary position may be misaligned.

The preliminary position is misaligned due to the following reasons.

Strong impact such as dropping or hitting

When comparing the state of “Misaligned Preliminary Hand Position” to that of a weight scale, it is like “a scale which is unable to display the correct weight because its needle is not set to the zero position before weighing.”

Adjusting the preliminary position of the hour, minute

and small second hands (Automatic hand position adjustment function)

The hour, minute and small second hands have an “automatic hand position adjustment function,” which automatically corrects an incorrect preliminary position. The automatic hand position adjustment function is activated once a minute for the small second hand and at 12:00 both for the AM and PM for the hour and minute hands.  This function works when the preliminary hand position is misaligned due to external factors

such as strong impact or magnetic influence. It does not work to adjust accuracy of the watch or slight misalignment which may occur during the manufacturing process.

Charging the solar battery

The stopped watch was exposed to an adequate light for longer than the time required to fully charge the watch, however, it does not resume its normal 1-second interval movements.

The amount of exposed light is too weak. The time for charging the watch is not sufficient.

The time required for charging the watch depends entirely on the amount of exposed light the watch receives. Refer to“ Standard charging time” to charge the watch.

P. 1 3

The small second hand is stopped even when the watch is charged for longer than the time required to fully charge the watch (P. 9 ).

The watch was not charged for a long time and has been discharged completely.

Contact the retailer from whom the watch was purchased.
