Hand
Movement
The seconds hand moves
at two-second intervals.
The energy depletion forewarning
function is activated. (P.40)
If the seconds hand moves at two- or
five-second intervals while you wear
the watch everyday, the watch is in a
condition where it cannot acquire
sufficient light, for instance, the watch
is concealed under a long sleeve shirt.
Fully charge the watch so that the
seconds hand may move at one-second
intervals.
Be careful not to conceal the watch
under a sleeve, etc., while wearing it.
When taking off the watch, place it in as
bright a location as possible.
P.38
The seconds hand moves
at five-second intervals.
The stopped seconds
hand pointing to the
15-second position
started operating.
The power save function has been
activated. (P.41)
When the watch is not exposed to
adequate light for a certain period of
time, the power save function to limit
energy consumption is automatically
activated.
Wait until the current time is displayed.
No operation is needed. (This is not a
malfunction.)

Hand
Movement
The stopped seconds
hand pointing to the
45-second position
started operating.
The power save function has been
activated. (P.41)
When the watch is not exposed to
adequate light for a certain period of
time, the power save function to limit
energy consumption is automatically
activated.
1.
Fully charge the watch so that
the seconds hand may move at
one-second intervals.
2. After that, if the watch displays
the incorrect time, receive a
radio wave as needed.
P.21,
P.38
The watch hands advance
rapidly unless a button is
pressed. After the rapid
advancement is
completed, the watch
resumes its normal
movement.
The power save function has been
activated. (P.41)
The automatic hand position alignment
function was activated. (P.71)
When the hand positions deviate to
display incorrect time as a result of
external influences, etc., the watch
automatically corrects the hand
misalignment by the automatic hand
position alignment function.
No operation is needed. (This is not a
malfunction.)

Reception
of a radio
signal
The watch is unable to
receive a radio signal.
The reception results have
failed and the seconds
hand points to N (the watch
does not receive a radio
signal).
The watch was moved while it was
receiving a radio signal.
(It takes 12 minutes at the longest to
receive a radio signal successfully.)
Do not move the watch while it is
receiving a radio signal.
Because it takes time to receive a radio
signal successfully, leave the watch
untouched for 12 minutes at the longest.
P.27,
P.61
The watch was left where the radio
signal was weak or where it was unable
to receive a radio signal. (P.28)
Place the watch where it is able to easily
receive a radio signal.
P.27
Transmitting stations may have
stopped transmitting radio signals for
some reason. (Transmission stop)
Check the website of each transmitting
station for further information
concerning a transmission stop.
Attempt to receive a radio signal again
after a while.
P.29
The time difference is set to regions
other than the radio signal reception
ranges.
1. Check the set time difference and
set the correct time difference.
2. When the watch is not displaying the
precise time, receive a radio signal
again if necessary.

Charging
the solar
battery
The stopped watch was
exposed to an
adequate light for
longer than “the time
required to fully charge
the watch”, however, it
does not resume its
normal one-second
interval movements.
The amount of exposed light is too
weak.
The time for charging the watch is not
sufficient.
The time required for charging the
watch depends entirely on the amount
of exposed light the watch receives.
Refer to “Guide to charging times” to
charge the watch.
P.39
The watch’s energy was depleted due
to no exposure to light for a long period
of time.
Refer to “In case of an abnormal
movement” to reset the system.
P.79
The built-in IC of the watch has fallen
into an unstable condition.
Even though the watch was
sufficiently charged and the
watch hands move, the time
is not correct.
The watch’s energy was depleted due
to no exposure to light for a long period
of time.
Misalignment
of the time
and hand
positions
The watch temporarily
gains or loses time.
The watch has been left in an extremely
high or low temperature place for a long
time.
1. When the watch returns to a normal
temperature, it will display the
precise time as before.
2. If the watch still gains or loses the
time, conduct manual reception if
necessary.
3. If the watch cannot resume normal
movement even after conducting
the above mentioned procedures,
consult the retailer from whom the
watch was purchased.
