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.

1 Features
This is a GPS solar watch.
GPS signal reception
This watch can be set to the precise local time anywhere in the world by
pushing just one button.
DST (Daylight SavingTime) 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.”
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.
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.
Automatic time adjustment function
This watch automatically adjusts the time in accordance with
action patterns during use.
When the watch has sensed sufficient 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.

76
Standard Charging Time
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.

4 Time zone
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 as of March 2015.
DST (Daylight SavingTime)
Depending on the area, DST (Daylight SavingTime) 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.
5 Time zone display and list of time zones around
the world
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 March 2015.
The displays of city code and the time difference from UTC are subject to
change depending on model.
“·” between figures of the display of time difference shows that there is a
time zone in that place.

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 doing so near time zone
boundaries. 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.

If the official time zone has changed in a region
after the watch’s time zone data was configured,
the correct time will not be displayed even
after receiving GPS signals. Please perform the
following operations to display the correct time:

< To set the time of this watch in a region where the official time zone has changed >
1. Select the time zone appropriate for the current time in the target region by manual time zone
setting.
→For details, please refer to “7. Manual time zone selection” P. 16
2. Next, adjust the time by manual time adjustment.
→For details, please refer to “9. How to manually adjust the time” P. 20
3. When using the watch within the same time zone, the correct time will be displayed after
automatic (GPS) or manual time adjustments.
4. When moving from a region where the official time zone has changed to a different time
zone, then back to the region where the official time zone has changed, carry out the same
operations from 1. - 3. as indicated above to display the correct time in the region where the
official time zone has changed.

1 Características
Este es un reloj solar GPS.
Recepción de señales GPS
Este reloj puede ajustarse a la exacta hora local en cualquier parte del
mundo, pulsando solo un botón.
El DST (Horario de Verano) se puede configurar de manera manual.
El reloj ajusta la hora rápidamente al recibir las señales GPS de los satélites
GPS.
El reloj responde a un total de 40 zonas horarias alrededor del mundo.
Cuando cambie la región o zona horaria donde esté usando el reloj, por
favor realice la operación de “ajuste de zona horaria”.
Función de carga solar
Este reloj funciona por carga solar.
Exponga la esfera a la luz para cargar el reloj. Cuando está completamente
cargado, el reloj funciona alrededor de 6 meses.
Cuando se agota toda la energía almacenada en el reloj, toma tiempo
volver a cargar el reloj por completo, por lo que debe recordar cargarlo
regularmente.
Función de ajuste horario automático
Este reloj ajusta automáticamente la hora de acuerdo con patrones
de acción durante el uso.
Cuando el reloj detecta suficiente luminosidad bajo el cielo abierto,
automáticamente recibe señales GPS de los satélites GPS. Esta
función permite al reloj ajustar la hora de manera automática y
exacta incluso durante el uso del reloj.
Este reloj no puede recibir las señales GPS cuando la energía
almacenada no es suficiente.
