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.
Reception of leap second data
2-sec interval movement/5-sec interval movement are brought about
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.
Restriction on
function/display
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
stop.
Reception is not started even with operation of
GPS signal reception.
Automatic time adjustment does not work.
Solution
First, charge the watch by expose to light until
the second hand moves at 1-sec intervals.
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.)
Charge the watch until the indicator hand
points to the “level position (middle)” or “F
(full).”
Carry out time zone adjustment to set the
time.
