Please charge the watch fully before use
by exposing it to light.
When the watch does not operate according to the
instruction manual, it is insufficiently charged.
Charge the watch for at least 3 hours approximately
20 cm (8 in) away from a fluorescent or incandescent
lamp (30 W) as a light source. When charging, do
not place the watch too close to the light source to
prevent the watch from becoming too hot.
* When charging the watch under direct sunfight,
charge for at least 50 minutes.

1. Features
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.
6 7
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.58 for information on the procedure for canceling
the manual power save function.)
A secondary battery is used in this watch to store electrical energy. This
secondary 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).
[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.

<0-Position Correction (Setting to the Watch Base Position)>
When setting the 0-position of each hand, always make sure to turn the crown
forward (clockwise) to set each hand to its 0-position in the clockwise direction.
1. Turn the crown while in the normal position to set the mode hand to the
chronograph [CHR] mode.
2. Pull the crown out to the second click (0-position correction position).
• The second hand, minute hand, hour hand, 24 hour hand, UTC hour hand
and UTC minute hand rapidly advance to the position stored in memory.
• "HR" lights during digital display 2 indicating that the watch is in the
correction state.
3. Turning the crown forward (clockwise) allows correction to be made in the
positive direction. Turning the crown continuously allows the 0-position to be
corrected continuously.
4. Pressing button (A) switches the correction location between "MIN" (minute
hand) and "SEC" (second hand) each time it is pressed.
5. Turn the crown forward (clockwise) to align each hand at the 0-position at
each correction location. Although correction can be made in the negative
direction by turning the crown backward (counter-clockwise), always make
sure to set the 0-position by turning the crown forward to ensure that the 0-
position is set correctly.
• The 24 hour hand is corrected in conjunction with the hour hand. 15
<0-Position Check>
1. Turn the crown while in the normal position
to set the mode hand to the chronograph
[CHR] mode.
2. Pull the crown out to the second click (0-
position correction position).
• The second hand, minute hand, hour
hand, 24 hour hand, UTC hour hand and
UTC minute hand rapidly advance to the
0-position (12:00 position).
Note:
• When each hand is not at the 0-position,
perform the "0-position correction"
procedure. If this 0-position is out of
alignment, each hand will not indicate the
correct position.
14

17
• The UTC hour and minute hands are corrected in conjunction with the
minute hand.
• The second hand can only be corrected in the forward (clockwise) direction
only.
6. After correcting, return the crown to the normal position.
• After correcting the 0-position of each hand, reset the time, calendar and
other modes before using the watch.
Note:
• None of the buttons on the watch operate during movement of each hand.
Operate the buttons only after the hands have stopped moving.

and the date of the city displayed by digital display (the times are switched at
this time as well).
20
Pressing buttons (A)
and (B) simultaneously
Analog time: 10:10 AM (Tokyo: TYO)

• When digital time is corrected, the second, minute, hour, 24 hour and UTC
hour and minute hands of the analog time are corrected automatically in
conjunction with digital time.
1. Turn the crown and set the mode hand to the time [TME] mode.
2. Press either button (A) or button (B) to access the city to be corrected.
3. When the crown is pulled out to the second click (time setting position), the
watch enters the time correction state.
4. When button (A) is pressed, the location to be corrected changes each time it
is pressed. Select the location to be corrected. (The location that is flashing
is the location that can be corrected.)
• When button (B) is pressed in the [SMT] daylight savings time correction
state, daylight savings time can be set (ON) or canceled (OF).
