§1. FEATURES
This watch is a solar-powered watch that contains a solar cell in its face that drives the watch by
converting light energy into electrical energy. It is equipped with numerous functions including a
perpetual calendar that changes the date automatically (day, month and year change automatical-
ly through February 28, 2100 even in leap years), a time difference correction function that makes
it possible to easily change the time difference without stopping the watch, and a power save
function that reduces current consumption when the solar cell is not exposed to light.
§2. BEFORE USING
This watch is a solar-powered watch. Make sure to charge the watch prior to use by
adequately exposing it to light.
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 circuit will continue to keep time for about 5 years without additional charging (when the
power save 2 function is operating).
<Proper Use of this Watch>
To use this watch comfortably, make sure to recharge it before it stops running completely. Since
there is no risk of overcharging (Overcharging Prevention Function) no matter how much the watch
is charged, it is recommended that the watch be recharged everyday.

§4. SETTING THE TIME AND DATE
If the watch is provided with a cover open, the cover to set the time or date, and then close the
cover once the time or date has been set.
Setting the Time
1. When the crown is pulled out to the second click (time setting position), the second hand
rapidly advances to the 0 seconds position and stops.
Note: Align the hands at the reference position after performing the all-reset procedure
when the second hand does not stop at the 0 seconds position.
2. Turn the crown and set the time.
qWhen the crown is turned to the right, the hour and minute hands move forward (clock-
wise).
wWhen the crown is turned to the left, the hour and minute hands move backward (counter-
clockwise) .
* Turning the crown continuously causes the hands to advance rapidly. Turn the crown to
either the left or right to stop the hands from advancing rapidly.
Note 1: When correcting in the forward direction, the date changes when the hour and
minute hands indicate 12:00 AM. However, when the date is changed in the case the
hands are advancing rapidly, the hour and minute hands pause at 12:00 AM and
then resume advancing rapidly after the date has changed.
Note 2: When correcting in the backward direction, the date does not change even if the
hour and minute hands pass 12:00 AM.
3. Retun the crown to the normal position in synchronization with a telephone time signal or other
time service.

Setting the Date
•This watch is provided with a perpetual calendar function. Once it is set, the year, month and
date change automatically, including leap years.
1. When the crown is pulled out to the first click (calendar correction position), the second hand
moves to the year and month position stored in memory and stops.
2. Turn the crown and set the date.
qTurn the crown to the right to set the second hand to the position corresponding to the year
(number of years elapsed since the most recent leap year) and month. Turning the crown
continuously causes the second hand to advance rapidly.
Examples:
* In the case of December in a leap year: Align the second hand at 0 seconds.
* In the case of April, in a year that is three years after the most recent leap year: Align the
second hand at 23 seconds (between 4:00 and 5:00).
wThe date is advanced by one day if the crown is turned to the left.
•Turning the crown continuously causes the date to be advanced continuously. Turn the
crown to either the left or right to stop the date from advancing continuously.
3. Always make sure to return the crown to the normal position after setting the date.
The second hand advances to the current seconds and the hands begin to move.

<When Setting the Date by Continuously Turning the Crown>
The date can be set easily by stopping advancing the date rapidly two to three days before the
correct date and then advancing the date one day at a time.
<When the Date has been Set to a Date that does not Exist>
The date automatically changes to the first day of the following month when the crown is returned
to the normal position from the date correction state.
Examples:
•Normal Years:
March 1 when the date has been set to February 29, 30 or 31.
October 1 when the date has been set to September 31
•Leap Years:
March 1 when the date has been set to February 30 or 31.
October 1 when the date has been set to September 31
Correcting the Time Difference
•When button (A) is pressed and the crown is turned continuously, time difference can be cor-
rected in 1 hour units. Time difference cannot be corrected continuously.
The time difference can be corrected for 30 seconds after button (A) has been pressed or for
30 seconds after time difference correction (after the hands finish moving).
1 . Put the crown in the normal position.
2. When button (A) is pressed, the second hand makes one revolution to indicate that the watch
is in the time difference correction state.
3. Correct the time difference by turning the crown to the right or left.
•When the crown is turned continuously to the right, the minute and hour hands are corrected
forward (clockwise) by one hour.
•When the crown is turned continuously to the left, the minute and hour hands are corrected
backward (counter-clockwise) by one hour.
Note 1: If the time difference is corrected in the forward direction, the date after the hands are
finished moving is corrected by +1 day when the hour and minute hands pass 12:00
AM. Pay attention to AM and PM when correcting the time difference.
Note 2: When returning the time difference to its original setting, return the hour and minute
hands in the opposite direction in which they were corrected. If the time difference is
corrected in the backward direction, the date after the hands are finished moving is
corrected by -1 day when the hour and minute hands pass 12:00 AM. This takes
about two minutes, however, since the date is corrected in the forward direction.

Example:
Setting the time difference of London (local time) when the time in Tokyo (home time) is
10:00 AM:
The time difference between Tokyo and London is -9 hours. Since it is 1:00 AM in London when it
is 10:00 AM in Tokyo, in the case of correcting the time difference at this time:
1. Press button (A).
2. Turn the crown to the left to turn the hands backward (counter-clockwise) by 9 hours .
Note: If the crown is turned to the right to move the hands clockwise to set the time to 1:00,
the time will be 1:00 PM and the calendar function will not operate correctly, prevent-
ing the date from changing at the proper time.
Case of Correcting Time Difference by 9 Hours
✩The time difference cannot be corrected when the second hand is moving at two-second
intervals indicating that the watch is insufficiently charged. Correct the time difference
after charging the watch by exposing it to light so that the second hand returns to one-
second interval movement.

<Insufficient Charging Warning Function>
The second hand moves at two-second intervals
to indicate that the watch is insufficiently
charged. The watch stops after about 2 days
have elapsed. Expose the watch to light to return
the second hand to one-second interval move-
ment.
<Time Setting Warning Function>
When the watch is again exposed to light after
stopping, although the second hand begins to
move, since the time is incorrect, the second
hand moves irregularly at two-second intervals
to indicate that the time is incorrect. Reset the
time after the watch has been sufficiently
charged. The second hand will continue to move
irregularly at two-second intervals unless the
time is reset.
<Overcharging Prevention Function>
The overcharging prevention function is activated when the secondary battery is fully charged so
that it is not charged further.
<Power Save 1>
When power is no longer generated as a result of light not shining on the solar cell, the second
hand stops and the watch enters the Power Save 1 state to reduce power consumption of the
secondary battery. The minute and hour hands continue to keep time even though the second
hand is stopped. Furthermore, operation of the calendar is linked with the movement of the hour
and minute hands.
<Power Save 2>
When the Power Save 1 state continues for about 3 days, the watch automatically switches to the
Power Save 2 state and movement of the hour and minute hands as well as calendar operation
stop to further reduce power consumption of the secondary battery more than Power Save 1.
Note:
The power save function is not activated even when power is not generated as a result of light not
shining on the solar cell during the time the secondary battery is fully charged and the over-
charging prevention function is activated.
<Canceling Power Save>
The power save function is canceled when the solar cell is exposed to light and power genera-
tion is resumed. Each of the hands advance rapidly to the current time and begin moving. The
date is also advanced continuously to the current date.
