IN CASE OF AN UNUSUAL MOVEMENT OF THE SECOND HAND

English
＜Ready for leap second data reception＞
…
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.
※…
“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.)
The indicator hand displays as shown at
the right when GPS signals are received
(time zone adjustment or time adjustment)
around June or December (display of being
ready for leap second data reception or
receiving leap second data). At this time,
the second hand points to any of the 0 to
18-sec positions to indicate the waiting
time until the leap second data reception
by minutes. The waiting time is subtracted
for each minute, and when the second
hand points to the 0-sec position, the leap second data reception is started.
It is recommended you move to a place where GPS signals can be easily
received.
※…The…position…of…the…second…hand…is…an…indication…of…the…time…until…the…leap…second…data…reception…is…
started.
…(When…the…second…hand…points…to…the…6-sec…position,…it…means…that…the…reception…will…be…started…
approximately…6…sec…later.)
※…At… this… time,… the… second… hand… does… not… move… at… 1-sec… intervals,… however,… it… does… not… mean… a…
failure.
The second hand moves in the same manner as the manual time adjustment during the leap
second data reception.
When the leap second data reception is completed, after the reception result is displayed, the
second hand starts moving at 1-sec intervals.
The indicator hand also 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.

Leap second (Automatic leap second reception function)
Energy depletion forewarning function (Second hand movement and watch state)
When the energy stored in the watch runs low, the energy depletion forewarning function will work.
When the energy stored in the watch runs low, charge the watch by expose to light.
※……When…the…energy…depletion…forewarning…function…works,…the…watch…does…not…operate…even…with…operation…of…the…buttons…and…crown.…
… (Be…assured…that…it…does…not…mean…a…failure)
Movement of the second hand shows the state of the watch (working functions).
2-sec…interval…movement
5-sec…interval…movement
State
The…second…hand…moves…at…2-sec…intervals.
The…second…hand…moves…at…5-sec…intervals.

・…Reception…is…not…started…even…with…operation…of…
GPS…signal…reception.
・Automatic…time…adjustment…does…not…work.
・…The…hour…hand,…minute…hand,…date,…and…sub-dial…

・…Reception…is…not…started…even…with…operation…of…

・Automatic…time…adjustment…does…not…work.
Solution
①…First,…charge…the…watch…by…expose…to…light…until…
the…second…hand…moves…at…1-sec…intervals.
②…Keep… in… mind… to… charge… the… watch… until… the…
indicator… hand… points… to… the…“level… position…
(middle)”…or…“F… (full).”…… (If… the… indicator… hand…
points…to…“E,”…GPS…signals…cannot…be…received.)…
①…Charge…the…watch…until…the…indicator…hand…
points…to…the…“level…position…(middle)”…or…“F…
(full).”…
②…Carry… out… time… zone… adjustment… to… set… the…
time.
