2. Before Using
Before using, please fully charge your watch by exposing the solar cell (watch dial) to
light while referring to section 6 entitled "General Reference for Charging Times".
Once fully charged, the watch will continue to keep the correct time for about 6 months.
<For Optimum Use of this Watch>
In order to use this watch comfortably, try to keep the watch amply charged at all times.
There is no risk of overcharging no matter how often the watch is charged
(Overcharging Prevention Feature). It is recommended to charge the watch everyday.

In the case the month correction button is of the screw lock type, operate the month
correction after first turning the “button cover” around the outside of the button to the
left to loosen the screw. The button is unable to operate properly if the screw is not
adequately loosened. Once you have finished operating the month correction button,
turn the “button cover” to the right and tighten securely. Please note that if the button
cover is not adequately tightened, the button may be bent or it may be accidentally
depressed while wearing the watch causing the month to be changed inadvertently.

[Procedure for Setting Time and Date]
Setting the Day
1. Pull the crown out to the time correction position (second position).
2. Turn the crown to the right (clockwise) and set the day to the current day.
• The displayed day begins changing at around 12:00 AM and finishes changing at
about 5:00 AM.
Setting the Moon Phase
1. Pull the crown out to the date correction
position (first position).
2. Turn the crown to the right (clockwise)
and set the current moon phase.
• The moon phase of a particular day can
be read from a newspaper and so forth.
Set the moon mark while referring to
"Reading the Moon Phase" following.

<Reading the Moon Phase>
The moon phase display does not display the shape of the moon itself, but rather simply
indicates the moon phase. It can be used to provide an approximate indication of the
moon phase.

<For More Accurate Setting of the Moon Phase>
The moon phase can be set more accurately by setting the time during a new moon
(when the moon mark cannot be seen: moon phase: 0) or during a full moon (when the
moon mark is directly above in the 12:00 direction : moon phase: 15).

Setting the Date and Month
1. Pull the crown out to the date correction position (first position).
2. Set the date and month.
• The date hand turns to the right when the crown is turned to the left (counter-
clockwise).
• The month changes when the month correction button is pressed.
[When the Date is Set from the 3rd to the 30th]
(1) Turn the crown to the left and set the date hand to today's date.
(2) Press the month correction button and set the month to the current month.
[When the Date is Set to the 31st]
(1) Temporarily set the date to the 30th.
(2) Press the month correction button and set the month to the current month.
(3) Set the date to the correct date of the 31st.
[When the Date is Set to the 1st or 2nd]
(1) Temporarily set the date to the 30th.
(2) Press the month correction button and temporarily set the month to the previous
month.
Examples: Set the month to December when setting the month to January
Set the month to February when setting the month to March
(3) Set the date to the correct date of the 1st or 2nd.
The month changes to the current month simultaneous to the date changing from
the 31st to the 1st.
3. Return the crown to the normal position.
14 15
Setting the Time
1. Pull the crown out to the time correction position (second position) when the second
hand reaches the 0 seconds position.
2. Turn the crown to the right (clockwise) and set the time.
• The day changes immediately after about 5:00 AM. Set the time while paying
attention to AM and PM by referring to the time when the day has changed.
3. Return the crown to the normal position in synchronization with a telephone or other
time service.
[Helpful Hint for Setting the Time Accurately]
After first stopping the second hand at the 0 seconds position, advance the hour hand
and minute hand 4-5 minutes past the correct time and then turn it back in the counter-
clockwise direction to the correct time to accurately set the time.
[Notes]
• If the date is corrected when the time on the watch is between 9:00 PM and 12:00
AM, the date may not change on the following day. Avoid correcting the date
during this time.
• The calendar operates based on a 31-day month. Correct the date by turning the
crown to the to the left to set to the first day of the following month in months
with less than 31 days (months with 30 days and February).
• Avoid correcting the month when the date hand indicates a date from the 31st to
the 2nd. If you want to correct the month during this time, wait until the date
hand is outside the range of the 31st to the 2nd. Then reset the date hand to the
correct date.
• When turning the crown to the left (counter-clockwise) when correcting the time
or day, the changing of the date may change a day late during normal use.

Warning Display] [Watch Stopped]
If insufficiently charged
When charged
If the capacity of the
secondary battery becomes

The time is incorrect since the
watch has stopped as a result of being
insufficiently charged. Reset the
watch to the correct time. Sufficiently charge the watch by exposing to light until the watch hands begin to move.
2 seconds
The second hand changes to
2-second interval movement
2 seconds
When the watch
becomes
insufficiently
charged, the watch
display changes as
shown below.
<Insufficient Charge Warning Feature>
When the watch becomes insufficiently charged, the
second hand begins 2-second interval movement to
indicate that the watch is insufficiently charged.
• Although the watch continues to run normally at this
time, the watch will stop after about 4 days have passed
since the watch has become insufficiently charged.
Charge the watch by exposing to light to return to the original 1-second interval
movement. Sufficiently charge the watch even after it has returned to 1-second
interval movement to ensure that it can be used comfortably. There is no risk of
overcharging since the watch is provided with an overcharging prevention feature.
• Although the watch will begin to run again when exposed to light after it has
stopped due to being insufficiently charged, since the time is incorrect, reset the time
after sufficiently charging the watch.

<Overcharging Prevention Feature>
When the secondary battery becomes fully charged as a result of exposing the watch dial
(solar cell) to light, the overcharging prevention feature is activated automatically to
prevent the battery from being charged further. Consequently, there is no degradation in
the performance of the solar cell or secondary battery no matter how often the watch is
charged. This lets you expose the watch to light without worrying about overcharging.
<Quick Start Feature>
The watch will stop running if it is not charged at all. The watch hands will begin to
move after about 10 seconds when the watch is exposed to light. (The time until the
hands begin to move varies depending on the model of the watch and the intensity of the
light.) However, please note that the watch may stop again since it will not be
adequately charged if the light is blocked at this time.
6. General Reference for Charging Times
The time required for charging 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.
* Charging time refers to the amount of time the watch is continuously exposed to light.

[Note]
• Once fully charged, the watch will continue to run for about 6 months with any
additional charging. As shown in the table above, a considerable amount of time is
required until the watch starts running once the watch has stopped as a result of
being insufficiently charged. Try to keep your watch sufficiently charged at all
times by charging everyday.
Furthermore, it is recommended to charge your watch by exposing to direct sunlight
once a month.
