• INSTRUCTION MANUAL
A. BEFORE USING
This watch is not powered by an ordinary battery,
but by converting photo energy into electric energy.
A secondary battery is used in this watch to store
electrical energy. This secondary battery is a
clean energy battery which does not use any
toxic substances such as mercury. Once fully
charged, the two-hand model will continue to
run for about 5 months, while the three-hand
model will continue to run for about 2 months,
without further charging.
To use this watch comfortably, make sure that the
watch is always recharged before it stops.
There is no risk of overcharging this watch.
(Overcharge prevention function is included.)
B. SETTING THE TIME
Setting the time
1. Pull the crown out to the time setting position (the
second hand will stop when the crown is pulled
out in the case of the three-hand model).
2. Turn the crown to set the time.
3. After setting the time, firmly push the crown back
in to the normal position.
C. FUNCTIONS OF SOLAR POWERED WATCH
If the charge becomes insufficient, a warning
function will be activated that causes the display to
change as shown below.
Refer to the explanations of each function on the
following page for further details.
Insufficient Charge Warning Function
In the case of the two-hand model, the minute hand
moves by one minute interval movement, and in the case
of the three-hand model, the second hand moves by two
second interval movement to indicate the insufficient
charging. Although the watch keeps the correct time when
this happens, the watch will stop after about 5 days in the
case of the two-hand model or about one day in the case
of the three-hand model, after the start of the one minute
interval movement or two second interval movement.
Recharge the watch by exposing to light. The watch will
then begin to run normally again.
Before using, expose to light and make sure
the watch is fully charged.
Since it takes time to recharge the watch until
it starts running again once it has stopped, try
to make sure the watch is charged every day.
When the watch is stopped, the watch hands
will begin to move when the watch is charged
for about 5 hours in the case of the two-hand
model or about 1 hour in the case of the
three-hand model at 3000Lux (under a
fluorescent light at a distance of about 20 cm
(8 inch)).
Three-Hand Model
(One second interval
movement)
: Second hand moves
once every second.
Two Hand Model
(20 second interval
movement)
: Minute hand moves
once every 20 seconds.
Three-Hand Model
(Two second interval
movement)
: Second hand moves
once every two seconds.
Two Hand Model
(One minute interval
movement)
: Minute hand moves
regularly in three steps
once every minute
Three-Hand Model
(Irregular two second
interval movement)
: Second hand moves
irregularly once every
two seconds.
Two Hand Model
(Irregular one minute
interval movement)
: Minute hand moves
irregularly in three steps
once every minute

Time Setting Warning Function
Although the watch hands will begin to move when
the watch is charged after stopping, since the time
is incorrect, the minute hand will move by irregular
one minute interval movement in the case of the
two-hand model, or the second hand will move by
irregular two second time interval movement in the
case of the three-hand model to indicate that the
time is incorrect. When this happens, fully charge
the watch and reset the time. The watch will
continue to run by the irregular interval movement
until the time is reset even if fully charged.
Overcharge Prevention Feature
You can recharge without worry
Once the secondary battery is fully recharged, the
overcharging prevention feature comes into
operation and prevents over-recharging.
D. CARE AND HANDLING DURING CHARGING
Notes on use
Take care to charge your watch during use.
Please note that if you wear long sleeves, the watch
can easily become insufficiently charged because it
is hidden and not exposed to light.
• When you take the watch off, place it in as bright a
place as possible, and it will always continue to
run properly.
Notes on recharging
• Avoid recharging at high temperatures (over about
60C/140F), otherwise the watch will be damaged
during recharging.
(eg) Charging the watch near a light source that
easily becomes hot, such as an incandescent
lamp or a halogen lamp.
Charging in a place that easily becomes hot such
as a dashboard.
When you charge the watch by an incandescent
lamp, take a distance about 50cm (20in) from the
light source to prevent extremely high temperature.
E. REPLACING THE SECONDARY BATTERY
Unlike ordinary batteries, the secondary battery
used in this watch doesn’t have to be
periodically replaced due to repeated charging
and discharging.
CAUTION
Never use another battery different from the
secondary battery used in this watch.
The watch structure is so designed that a different
kind of battery other than that specified cannot be
used to operate it. In case a different battery such
as a silver battery is used by some chance, there is
a danger that it will be overcharged to burst, causing
damage to the watch and even the human body.
F. TIME REQUIRED FOR CHARGING
Time required for recharging may vary according to
the design (colour of the dial, etc.) and operating
environment. The following table will serve you as a
rough reference.
Full recharging time (Empty to full):The time for fully
recharge from stopped.
One day usage: The time required for the watch to
run for one day with one second interval movement
for 20 seconds interval movement.
*The recharging time is the time when the watch is
continuously exposed to radiation.
[Irregular one minute
interval movement]
[Irregular two second
interval movement]
