1. Features
This watch is a combination solar-powered watch that contains a solar cell in its
face that drives the watch hands, race timer, chronograph, alarm, and numerous
other functions by converting light energy into electrical energy.
It is also equipped with convenient functions including a power save mode that
reduces power consumption when light is not shining on the solar cell, UTC
(Coordinated Universal Time) and a world timer indicating the time and dates of
30 major cities around the world.

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).
[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).

16. About All-Reset
When this watch indicates an abnormal display or does not function properly (no
display, alarm continues to sound, etc.) as a result of being subjected to the
effects of static electricity or strong impact and so forth, perform the all-reset
procedure described below.
When performing the all-reset procedure, first make sure that the watch is
sufficiently charged.
<All-Reset Procedure>
1. Turn the crown to set the mode hand to the
chronograph [CHR] mode.
2. Pull out the crown to the first click (0-position
correction mode).
· The second hand, minute hand, hour hand, 24
hour hand, and function hand rapidly advance to
the 0-position stored in memory.
3. Press buttons (A), (B), and (C) simultaneously
and then release.
· All segments of the digital display are shown when any of the buttons is
released.
4. This fully lit display is canceled when the crown is returned to the normal
position.
· After canceling, a confirmation tone is sounded after which each of the hands
perform a demonstration movement in the order of the second hand, function
hand, and minute hand, to indicate that the all-reset procedure is finished.
· After the demonstration movement, pull the crown out to the first click to
switch the watch to the 0-position (base position) setting state.
Always make sure to set the 0-position (standard position) for the hour hand,
minute hand, second hand, 24-hour hand and function hand while referring to
“5. Checking 0-Position of Each Hand <0-Position Correction>”.
Note:
· After setting the 0 position (base position) for each hand, correctly reset the
time, calendar and other modes before using the watch.

[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, after the watch has stopped due to being
insufficiently charged, it will not return to the normal display unless the time and
date are set during the Insufficient Charging Warning state after the watch is
sufficiently charged by exposing it to light.
Digital Display
“CHARGE” flashes on digital display 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 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:
· Crown operations do not function (except for mode switching (with the crown
in the normal position)) in any of the modes.
· Button operations do not function, except for changing the city name
(UP/DOWN), in any of the modes.
· The alarm tone does not sound even if it is set.
· The chronograph is interrupted and reset even if measurement is in progress.
· Timing by the race timer is immediately interrupted even if timing is in
progress.
· 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 a sufficient charge, the watch returns to the
mode indicated by the mode hand.
[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
The all-reset display (12 hours, 00 minutes, 00 seconds, UTC or January 1 TU)
flashes in the time or calendar mode.
<Canceling the Time Setting Warning Function>
1. Set the mode hand to the time mode and pull the crown out to the first click to
set the time. Flashing of the digital display is only canceled in the time mode.
After correcting the time, return the crown to the normal position.
2. Set the mode hand to the calendar mode and pull the crown out to the first
click to set the date. Flashing of the digital display is canceled in the calendar
mode.
3. After correcting the date, return the crown to the normal position.
Note:
· The time setting warning function will not be canceled unless the time is first
set followed by setting the date.

[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.
[Power Save 1]
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 12 o’clock 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 standard position (12:00).
· Other hands continue to keep the correct time.
Digital Display
· In conjunction with the analog second hand stopping at the 12 o’clock
position, the entire digital display goes out. However, the race timer, alarm,
chronograph and other functions continue to measure time internally even
though there is no display.
<Canceling Power Save 1 >
Power Save 1 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 onesecond interval movement.
· The digital display reappears simultaneous to resumption of power
generation.
Note:
· During the time 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 temporarily becomes fully
charged.
[Power Save 2]
When the watch reaches the first 12:00 AM position (when the 24 hour hand,
hour hand and minute hand all reach the standard position) after the Power
Save 1 state has continued for 3 days, it enters the Power Save 2 state.
5150
Analog Display
· The 24 hour hand, hour hand, minute hand, second hand and function hand
stop at the standard position (12:00).
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.
<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 chronograph reset
display and the race timer and timer switch to the initial setting display.

19. Notes Regarding Handling of this Watch
<Try to keep the watch charged at all times.>
• 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.
• When you take the watch off, try to place it in as bright a location as possible
to ensure that it always keeps the correct time.
Notes: Charging Precautions
• Avoid recharging at high temperatures (over about 60°C / 140°F) since this
may result in damage 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.
• 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.
Full recharging time: Time required for recharging the watch from the stopped
state to the fully charged state.
Charging time for 1 day of operation: Time required for recharging the watch to
run for 1 day at one-second interval
movement.
