This is a GPS solar watch.
This watch has the following features.
GPS signal reception
This watch can be set to the precise
local time by just one button operation
anywhere in the world.
DST (Daylight Saving Time) is reflected
in the time that appears.
This watc h quickly adjus ts the time by
recei ving GPS signals
from GPS satellites.
This watch r esponds to
a total of 39 time z ones
around the world.
When the region or tim e
zone where the w atch is
used is changed, please
carry ou t operation of
“time zone adjustment.”
Unlike na vigation equ ipment, this G PS solar watc h is not design ed to consta ntly recei ve GPS signals f rom GPS satel lites witho ut any operati on.
This watch receives GPS signals only in the time zone adjustment mode, automatic or manual time adjustment mode.
Standard Charging Time
GPS signal reception con sumes a lot of en ergy. It i s necessary to charge the watc h by exposing i t to light so
that th e indic ator hand poin ts to the “middle” or “full” position. (If the charging st atus is displayed as “low,” the
reception will not s tar t even w ith man ual GPS signal r eception.)

When the watch has sensed sufficient brightness
under an open sky, it automatically receives GPS
signals from GPS sat ellites. T his func tion enables
the watch to automatically adjust the time precisely
even while you are

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 39 zones as of March 2018.
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.
If the time zone adjustment is successful, data
regarding the adoption of DST (Daylight Saving Time)
for the country in which the GPS signals were received
is reflected in the time that appears.
Daylight Saving Time is subject to change owing to circumstances
of the country or region as of March 2018.
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.

The following list shows the relationship between

Please refer to the seco nd hand posi tions below to set

DST (Daylight Saving Time) has been adopted in countries marked with a ★ .
In the Lord Howe Island time zone in Australia with a mark, the time is
advanced by 30 minutes while DST (Daylight Saving Time) is in effect.
This watch corresponds to DST in the Lord Howe Island time zone.
The time zone and adoption of DST (Daylight Saving Time) for each
region are current as of March 2018.

Time zone adjustment (to adjust the time zone and time by GPS signal
reception)

Time zone adjustment
The time zone where you are is localized to adjust the watch to the precise current time by just one button operation anywhere in the world.
This reflects the data regarding the adoption of DST (Daylight Saving Time) in the country that received the GPS signals.
The time automatically switches to adjust for the adoption and duration of DST (Daylight Saving Time) for countries that follow DST (Daylight Saving Time).
"Normal time" always appears for countries that do not adopt DST (Daylight Saving Time).
How to adjust the time zone
Go to a place where
GPS signals can be
1
easily received
Move to the outdoors
under an open sky
with good visibility.
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.

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.
Receiving Leap Second Data
When the GPS signal reception
(automatic time adjustment,
manual time adjustment,
or time zone adjustment) is
performed on or after December
1st and June 1st, the indicator
hand may display 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.
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.)

If the official time zone, etc., has changed in a region after the watch’s
time zone data or DST (Daylight Saving Time) 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 or DST (Daylight Saving Time) has changed >
1. Select the time zone appropriate for the current time in the target
region by manual time zone setting and do settings for DST (Daylight
Saving Time), as necessary.
→
2. Next, adjust the time by manual time adjustment.
→
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.
