(click on a topic)

This watch is a combination solar-powered watch that contains a solar cell in its face that drives the watch
hands, alarm, chronograph, timer and numerous other functions by converting light energy into electrical
energy.
It is also equipped with convenient functions including three power save modes that reduce power
consumption when light is not shining on the solar cell, and a "charge indicator" that roughly indicates how
much the secondary battery is charged.
2. BEFORE USING
This watch is a solar-powered watch. Before using, allow light to shine onto the watch so
that it is sufficiently charged.
If the manual power save function has been activated, cancel it before charging. (Refer to
p.19 for information on the procedure for canceling the manual Power-Save function.)
A rechargeable battery is used in this watch to store electrical energy. This rechargeable battery is a clean
energy battery that does not contain mercury or other toxic substances. Once fully charged, the watch will
continue to run for a maximum of 4 years without additional charging (when in the power save 2 mode). Please
note this is not a user replaceable item.
[Proper Use of this Watch]
To use this watch comfortably, make sure to recharge it before it stops running completely. There is no risk of
overcharging the watch no matter how often it is recharged (Overcharging Prevention Function).
It is recommended that the watch be recharged everyday for optimum performance.

16. FUNCTIONS UNIQUE TO SOLAR-POWERED WATCHES
Return to Table of Contents
Return to Table of Contents

[Insufficient Charging Warning Function]
(Analog Display)
Regardless of the display (Mode) of the watch at the time,
when the watch becomes insufficiently charged, the watch
changes to the time display and the second hand begins to
move at two-second-interval movement. Although the 24-hour
hand, hour hand and minute hand continue to keep the correct
time, the watch stops after about 1.5 days have elapsed after
the insufficient charging warning function is activated. When
this happens, charge the watch by exposing to light so that it
returns to one-second-interval movement.
However, if the watch again becomes insufficiently charged
without setting the time after it has been sufficiently charged by
exposing to light as a result of having stopped due to being
insufficiently charged, it will not return to the normal display
unless the time is set after again sufficiently charging.
(Digital Display)
"CHARGE" flashes on digital display area 2 in all modes.
<Digital Display in Each Mode>
• The watch displays the normal time display regardless of the position of the crown (pulled out to the first or
second click) in each mode except for the calendar mode.
• When the watch is in the calendar mode, the normal date display is displayed regardless of the position of the
crown.
Notes:
x Crown operations do not function <except for mode switching (with the crown in the normal position)>
in any of the modes.
x Button operations do not function, except for changing the city name (UP/DOWN), in any of the
modes.
x The alarm tone does not sound even if it is set.
x The chronograph is interrupted and reset even if measurement is in progress.
x Timing by the timer is immediately interrupted even if timing is in progress
x In the case the watch switches to the insufficient charging warning function as a result of being
insufficiently charged, it takes a minimum of 30 minutes for the watch to return to the normal operating
state even if sufficiently exposed to light.
<When the Insufficient Charging Warning Function is Canceled>
When the insufficient charging warning function is canceled as a result of exposing the watch to light and
sufficiently charging, the watch returns to the mode indicated by the mode hand.
Return to Table of Contents
Return to Table of Contents

[Time Setting Warning Function]
(Analog Display)
The watch stops when insufficient charging
continues for about 1.5 days. When the watch
is charged by exposing to light after having
stopped due to insufficient charging, each
hand is rapidly advanced to the base position
and stops. Each hand remains stopped until
the time is reset.
(Digital Display)

date.
x It takes a minimum of 30 minutes until the watch switches to the time setting warning display after the
watch has stopped due to insufficient charging even if the watch is exposed to light.
[Overcharging Prevention Function]
The overcharging prevention function is activated when the secondary battery is fully charged so that it is not
charged further. This allows the user to charge the watch without any risk of overcharging.
Return to Table of Contents
Return to Table of Contents

When power is not generated as a result of the solar cell not being exposed to light, the second hand stops
when it reaches the zero seconds position and the watch automatically enters the power save state to inhibit
power consumption of the secondary battery.
(Analog Display)
• The second hand stops at the base position (12:00).
• Other hands continue to keep the correct time.
(Digital Display)
In coordination with the analog second hand stopping at the zero seconds’ position, the entire digital display
goes out. However, the alarm, chronograph and other functions continue to measure time internally even
though there is no display.
<Canceling Power Save 1>
Power Save I is canceled when power generation resumes as a result of exposing the solar cell to light.
• The second hand rapidly advances to the current time and begins one-second interval movement.
• The digital display reappears simultaneous to resumption of power generation.
Notes: During the secondary battery is fully charged and the overcharging prevention function is activated, the
power save function is not activated even if power generation is interrupted as a result of the solar cell not
being exposed to light. In addition, the power save function is similarly not activated when the solar cell is
exposed to intense light and temporally becomes fully charged.
[Power Save 2]
When the Power Save I state continues for about 3 days and the minute hand reaches the base position
(12:00), the watch automatically enters the Power Save 2 state.
(Analog Display)
• The minute and second hands stop at the base position (12:00).
• Other hands stop moving at their current locations.
(Digital Display)
• The digital display remains completely out in continuation from the Power Save 1 state.
Notes:
• Crown and button operations do not function in any mode.
• The alarm tone does not sound even if it is set.
• The tone indicating that time is up does not sound in the timer mode.
<Canceling Power Save 2>
Similar to Power Save 1, Power Save 2 is canceled when power generation resumes as a result of exposing
the solar cell to light.
• Each hand rapidly advances to the current time and begins to move.
• The digital display reappears simultaneous to resumption of power generation. However, the chronograph
returns to the reset state and the timer switches to the initial setting display.

17. Power Save Features
[Power Save 1]

[Manual Power Save]
When not using the watch for an extended period of time, activating the manual power save function after first
charging the watch until all three bars of the graphic display of the secondary battery charge indicator are lit
enables the watch to be stored for a longer period of time. Furthermore, do not charge the watch while the
manual power save function is activated. First cancel the manual power save function before charging.
<Setting Manual Power Save>
The manual power save function is activated by setting the city name to "C65" and the time difference to "O"
while following the procedure described in “<Registration of Arbitrary City and Time Difference>” in section 14
on Using Zone Setting, and then returning the crown to the normal position.
(Analog Display)
• Each hand stops moving at its current location.
(Digital Display)
• The entire digital display is not lit.
Notes:
• None of the button operations function in any mode.
• The mode does not change even when the mode hand is attempted to be moved by turning
the crown.
<Canceling Manual Power Save>
Each hand rapidly advances to the current time and Manual Power Save is canceled when the crown is pulled
out to the second click.
Return the crown to the normal position after canceling the manual power save function. -P Each hand rapidly
advances to the current time and begins to move.
The digital display reappears simultaneous to resumption of power generation, and the alarm sounds for the
set duration. However, the chronograph returns to the reset state and the timer switches to the initial setting
display.
[Charge Indicator]
The charge indicator provides a simple graphic indication in digital display area 2 of the amount of charge
remaining in the secondary battery.
<Interpretation of Secondary Battery Charge Levels>
Fully charged Sufficiently charged Low charge Hardly any charge
When none of the bars of the graphic display are lit, the secondary battery has essentially become completely
discharged and the second hand begins two-second interval movement. Since the watch will stop due to
insufficient charging if this state continues for about 1.5 days, sufficiently charge the watch by exposing to light.

The time required for recharging varies according to the model of the watch (color of the dial, etc). The
following times are shown below to serve only as a reference.
Recharging time refers to the amount of time the watch is continuously exposed to light.
Charging Time
Full recharging time: Time required for recharging the watch from the stopped state to full charged.
Charging time for 1 day of operation: Time required for recharging the watch to run for 1
day at one-second-interval movement.
<Be sure to keep the watch charged at all times>
x Please note that if you routinely wear long sleeves, the watch can easily become insufficiently charged
as a result of it being concealed and unable to be exposed to light.
x When you take the watch off, try to place it in as bright location as possible to ensure that it always
keeps the correct time.
Notes: Charging Precautions
x Avoid recharging at high temperature (over about 60OC/1400F) since this may result in dam- age to the
watch as a result of reaching excessively high temperatures. Examples: Charging the watch in close
proximity to an incandescent lamp, halogen lamp or other light source that can easily reach high
temperatures, charging the watch in a location that reaches high temperatures such as on a car
dashboard.
x When charging the watch with an incandescent lamp, always make sure the watch is at least 50 cm (20
in.) away from the lamp so that it does not reach excessively high temperatures during charging.
