About energy
■ Energy depletion forewarning function (Two-second
interval movement and Five-second interval movement)
The energy depletion forewarning function is activated when the energy stored in the watch runs low.
In such a case, the seconds hand moves at two-second intervals.
If the watch continues to be in the state of two-second interval movement, the watch switches to five-second
interval movement, followed by a completely stopped state.
If the energy depletion forewarning function is activated, charge the watch sufficiently.

“Guide to charging times” → P.35
* Neither the button nor the crown can be operated while the seconds hand moves at two-second or five-second
intervals. (This is not a malfunction.)
* While the seconds hand moves at five-second intervals, the hour and minute hands, as well as the date, stop
operating.
* While the seconds hand moves at five-second intervals, the automatic reception function and manual reception
function will not work. After the watch is charged sufficiently and the seconds hand returns to normal one-second
interval movement, conduct the manual reception of radio signals to set the watch to the correct time. (“Automatic
reception and manual reception” → P.17)

SOLAR CHARGING FUNCTION
■ Power save function
This watch is equipped with a power save function which can suppress energy consumption when it is left without receiving
an adequate light source for a certain length of time.
* There are two types of power save mode.
Power Save 1
Power Save 2
Condition The watch is exposed to a state without receiving an
adequate light source for 72 hours or longer.
The watch is in an insufficient charging state for a long
time.
Situation
The seconds hand
stops pointing at the
15-second position,
and the hour and
minute hands, and
date also stop.
The watch conducts
automatic radio signal
receiving.
The seconds hand
stops pointing at the
45-second position,
and the hour and
minute hands, and
date also stop.
The watch does not
conduct automatic
radio signal receiving.
* The date shows “1”.
How to
handle the
situation
When the watch is exposed to an adequate light source
for 5 seconds or longer, or the button is pressed, it
displays the current time again after the seconds hand
is rapidly advanced.
After sufficiently charging the battery, set the watch for
the current time, if necessary.
Power Save 2
* While the watch is being charged, the seconds hand moves at “Five-second Intervals.” During the “Five-second Interval Movement,”
neither the button nor the crown can be operated.
* If the “Power Save 2” mode is prolonged, the stored power amount drops and the internal current time information stored will be lost.
When the watch returns to its normal movement of one-second interval after sufficiently charging the battery, set the current time by
receiving a radio signal. (“Automatic reception and manual reception”

Daily care
●
The watch requires good daily care
• Do not wash the watch when its crown is in the extended position.
• Wipe away moisture, sweat or dirt with a soft cloth.
• After soaking the watch in seawater, be sure to wash the watch in clean pure water and wipe it dry
carefully.
Do not pour running water directly from a faucet onto the watch. Put some water into a bowl first, and
then soak the watch in the water to wash it.
* If your watch is rated as “Non-water resistant” or “water resistant for daily use,” please do not wash the watch.

●
Turn the crown from time to time
• In order to prevent corrosion of the crown, turn the crown from time to time.
• The same practice should be applied to a screw down crown.
“Crown” → P.13
