For details, please read the

“8X82 (GPS Solar) Complete User Guide”

(http://www.seikowatches.com/support/ib/index.html).

Please carefully read the

instructions in this Complete User

Guide before using the watch.

Length adjustment service for metallic bands is

available at the retailer from whom the watch was

purchased. If you cannot have your watch repaired

by the retailer from whom the watch was purchased

because you received the watch as a gift, or you moved

to a distant place, please contact SEIKO WORLDWIDE

SERVICE NETWORK.The service may also be available

on a chargeable basis at other retailers, however, some

retailers may not perform the service.

If your watch has a protective film for preventing

scratches, make sure to peel it off before using the

watch. If the watch is used with the film on it, dirt, sweat,

dust, or moisture may be attached under the film and

may cause corrosion.

GPS signal reception

　Features

This is a GPS* solar watch.

Standard Charging Time

This watch can be set to the precise

local time by just one button

operation



anywhere in the world.



DST (Daylight Saving Time) can be set manually.

This watch quickly adjusts the time by

receiving GPS signals

from GPS satellites.

This watch responds to

a total of 40 time zones

around the world.

When the region or time

zone where the watch is

used is changed, please

carry out operation of

“time zone adjustment.”

GPS signal reception consumes a lot of energy. It is necessary to charge the watch by exposing it to light so

that the indicator hand points to the “middle” or “full” position. (If the charging status is displayed as “low,”

the reception will not start even with manual GPS signal reception.)

The figures of “Time required for charging the watch to start moving at one- second 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 partially charged for a shorter period, the

watch will resume one-second- interval movement. However, it may shortly return to two-second-interval movement. Use the charging time in

this column as a rough guide for sufficient charging time.

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

When the energy

stored in the watch

runs out completely,

it takes time to fully

charge the watch,

so please keep in

mind to charge the

watch regularly.

Solar charging Function

This watch operates by solar charging.

Expose the dial to light to charge the watch. Once

fully charged, the watch runs for approximately

6 months.

Automatic time adjustment function

This watch automatically adjusts the time in

accordance with action patterns during use.

When the watch has sensed suf ficient brightness under

an open sky, it automatically receives GPS signals

from GPS satellites. This function enables the watch to

automatically adjust

the time precisely

even while you are

using the watch.

This watch is

unable to receive

GPS signals

when the energy

stored in the

watch is low.

GPS is an abbreviation for Global Positioning System.

　Time zone

Based on Coordinated UniversalTime (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 as of January 2014.

Further, DST (Daylight SavingTime) is individually

adopted in countries and regions.

DST (Daylight Saving Time)

Depending on the area, DST (Daylight Saving Time) is

individually set.

Daylight SavingTime, or summer time, is a system

to lengthen daylight time by advancing 1 hour when

daylight time is longer during 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 varies depending

on the country.

Daylight SavingTime is subject to change due to circumstances

of the country or region.

Coordinated Universal Time

(UTC)

UTC is the universal standard time coordinated

through an international agreement. UTC is the

primary time standard for recording time around the

world. The time obtained by adding a leap second to

the “International Atomic Time (TAI)” is determined

based on the atomic clock around the world. It is

coordinated in order to compensate for deviations

from universal time (UT) which is astronomically

determined by the UTC.

　Time zone display and list of time zones around the world

Display of

time difference

The following list shows the relationship between

displays of the bezel and dial ring and time difference

from the UTC.

Please refer to the second hand positions below to set

the time zone or to check the time zone setting.

DST (Daylight SavingTime) is used in time zones with a mark.

In the Lord Howe Island time zone in Australia with a mark, the time is

advanced by 30 minutes while Daylight SavingTime (SummerTime) is in effect.

This watch corresponds to DST in the Lord Howe Island time zone.

The time zone of each region and DST (Daylight SavingTime) are as of

January 2014.

from which GPS signals are received).

Even when the hand

points to 4 units or more,

reception may not be

allowed.



Please note that it may be difficult to receive

GPS signals while you are in motion.

To cancel the

reception, press

Button A.

When the second hand

points to “Y” or “N,”

reception is completed.

During movement of the

date, the buttons cannot be

operated.

Manually set Daylight Saving

Time (DST).

The reception result is

displayed for 5 seconds.

Then, the hour and minute

hands move, and the time

and date are adjusted. (The

time zone is also adjusted

to the local time zone.)

Although the small second hand moves to the

0-second position 3 seconds after pressing

Button B, continue to press it.

When the second hand has reached

the 30-second position, reception is

started.

The indicator hand points to “4+.”

While the indicator hand points to “low” or ,

reception is not started even with operation

for reception.

When the hand points to “low,” charge the

watch by exposing it to light.

Check whether the watch is able/unable to

receive GPS signals

When the hand points to , reset the in-

flight mode ( ).

Press for

How to adjust the time zone

Time zone adjustment

Precautions on time zone adjustment

If the time zone is adjusted near a time zone boundary, the time of the adjacent time zone may be displayed.

In some areas the boundaries observed by the watch may not exactly correlate to the actual time zone markers on the land.

This does not indicate a malfunction. In this case, set the time zone in the manual time zone setting mode.

When the time zone is adjusted while traveling on land, avoid time zone boundaries to carry out time zone adjustment in the

representative cities in the time zone whenever possible. In addition, when the watch is used near time zone boundaries,

make sure to check the time zone setting, and manually set the time zone as necessary.

When the stopwatch is operating, the reception function will not be activated.
