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 T ime) can be s et 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 s tart moving at one - second intervals” are es timations of time re quired to charge the stopped
watch by exposing it to light until it moves at s teady one- second intervals. Even if the watch is par tially charged for a shor ter period, the watch will
resume one-second- interval movement. However, it may shor tly return to two-second-inter val movement. Use the charging time in this column as a
rough guide for sufficient char ging 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
accor dance with ac tion pat terns during use.
When the w atch 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 pr ecisely
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.

The indicator hand position shows whether this watch is able or unable to receive GPS signals.
In addition, for the low charging state, the movement of the second hand shows the energy depletion state in
further detail.
GPS signal reception requires a lot of energy. It is necessary to regularly charge the watch by exposing it to light.

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.
Further, DST (Daylight Saving Time) is individually adopted in countries and regions.
DST (Daylight Saving Time)
Depending on the area, DST (Daylight Saving Time) is individually set.
Daylight Saving Time, 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 Saving Time 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.
Each time zone is based on data as of January 2014.
Please be advised that regions for which the time zone is changed after 2014 cannot be accurately reflected.
