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 daily alarm function that be set based on a 24-hour clock, and a chronograph function that allows measurement of time in 1/20 second unit up to 59 minutes 59.95 seconds.

Before Using
This watch is a solar-powered watch. Please fully charge the watch before using it by 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 will continue to run for about one year without additional charging (when the power save feature is operating).

Power Save Feature
When power generation stops as a result of light not shining on the solar cell during the time/calendar (TME mode), the second-hand stops at the 12:00 position, and only the hour and minute hands move to save power. When light once again begins to shine on the solar cell, the second-hand advances rapidly to the current seconds and returns to moving at one-second intervals. Although varying according to the design, the power save feature is activated when the light does not shine continuously for 30 minutes or more, and the second hand has reached the 12:00 position.

< 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 Feature), it is recommended that the watch be recharged every day.

Functions Unique to Solar-Powered Watches
When the watch becomes insufficiently charged, the following warning features will be activated to inform the wearer that the watch is insufficiently charged

< Insufficient Charging Warning Feature>
When the capacity of the secondary battery decreases as a result of light not shining on the solar cell, the second-hand switches from a 1-second interval movement to 2- a second interval movement (insufficient charge warning feature). Although the watch continues to keep time accurately at this time, the watch stops after about 4 days have elapsed after the second hand has switched to a 2-second interval movement. When this happens, charge the watch by exposing it to light until the second-hand returns to a 1-second interval movement.

Notes

• When the chronograph, alarm 1, or alarm 2 mode is displayed, the watch automatically switches to the time display and begins a 2-second interval movement. However, the mode hand indicates the original mode. The watch returns to the original mode when it is sufficiently charged and the insufficient charge warning the feature is canceled.
• Chronograph measurement stop and the chronograph is reset even when the measurement is in progress.
• The alarm will not sound even if it is set.
• Crown (mode switching) and button operations will not function.

< When the Watch has Stopped due to Insufficient Charging>
When the capacity of the secondary battery decreases as a result of the watch not being exposed to light after the insufficient charge warning feature has been activated, the watch will stop due to being insufficiently charged. When this happens, sufficiently charge the watch by exposing it to light so that it returns to the normal time display (1-second interval movement).
Notes:

• Since the time is incorrect when the watch has stopped as a result of being insufficiently charged, make sure to reset the time before using it.
• If the watch has stopped as a result of being insufficiently charged, it takes at least 30 minutes until the watch returns to the normal time display even if it is exposed to light. Continue charging until the second hand begins to move.

< Overcharging Prevention Feature>
The overcharging prevention feature is activated when the secondary battery is fully charged so that it is not charged further.

< Power Save Feature>
When power is no longer generated as a result of light not shining continuously for 30 minutes or more on the solar cell during the time/calendar (TME mode) with the crown in the normal position or Position 1, the second- hand stops when it has reached the 12:00 position and the power save feature is activated to reduce current consumption. The 24-hour hand-hour hand and minute hand continue to keep the correct time even though the secondhand has stopped. Furthermore, the calendar is corrected in coordination with the 24-hour hand and hour hand.

Notes

During the time the secondary battery is fully charged and the overcharging prevention feature is operating, the power save feature does not operate even when power generation is interrupted as a result of not exposing the solar cell to light.
Similarly, the power save feature will also not operate when the secondary battery temporarily becomes fully charged as a result of exposure to intense light.

• When the power save feature has been activated when the crown is at Position 1 (calendar correction position), the data can be corrected by turning the crown.
• If the alarm is set (ON), the alarm will sound when the set alarm time is reached.
• The time until the power save feature is activated varies according to the model.

Canceling Power Save Feature

1. When power generation begins as a result of light shining on the solar cell, the power save feature is canceled and the second hand begins a 1-second interval movement.
2. Power save is also canceled when the position of the crown has been changed (from the normal position to Position 1 or Position 2) or the mode has been switched (chronograph or alarm mode) by turning the crown while in the normal position.

General Reference for Charging Times
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. Full recharging time: Time required for recharging the watch from the stopped state to fully charged Charging time for 1 day of operation: Time required for recharging the watch to run for 1 day at 1-second interval movement

Notes Regarding Handling of this Watch
< Try to keep this watch charged at all times.>
Please note that if your wear long sleeves, the watch can easily become insufficiently charged as a result of 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 is continuously kept charged continues to keep the correct time.

CAUTION: Charging Precautions
Avoid recharging at high temperatures (over about 60°C / 140°F) since this may result in damage to the watch during recharging. Examples: Charging the watch in close proximity to an incandescent lamp, halogen lamp, or another light source that can easily reach high temperatures, or 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.

Replacing the Secondary Battery
Unlike ordinary silver-based batteries, the secondary battery used in this watch does not have to be periodically replaced since it is able to be charged and discharged repeatedly.

Switching the Mode (Display Function)
This watch is equipped with four modes consisting of time/calendar, chronograph, alarm 1, and alarm 2. The mode changes when the crown is turned. The current mode can be confirmed with the mode hand.

Hand 0-Position Check and Correction
Before using this watch, check that the functions of the watch operate properly by performing the following procedure.
0-Position: This refers to the base position of each hand for enabling this watch to function properly.

[0-Position Check]
Turn the crown to switch the watch to the chronograph [CHR] mode. Pull the crown out to Position 1 to switch the watch to the 0-position correction mode. The 24-hour hand, hour-hand, minute hand, second hand, and function hand rapidly advance. Check that each hand indicates the 0-position.

0 Positions of Each Hand (Base Position)
24-hour hand: 24:00 The hour hand, minute hand: 00:00 Second hand: 00 seconds Function hand: 0-position (12:00 position) Perform the “0-Position Correction” procedure when the hands are not at the positions indicated above.
[0-Position Correction] 0-Position Correction of Function Hand: Pull the crown out to Position 1 in the chronograph [CHR] mode to correct the function hand. (1) Press button (A) to align the function hand at the 0-position immediately after the date has changed (12:00 position). Pressing button (A) advances the function hand by one second each time it is pressed. Continuously pressing the button (A) causes the function hand to advance continuously. The date changes by one day when the function hand completes four revolutions.

Note: Turning the crown by one revolution to the left causes the function hand to advance continuously (make four revolutions) and the date is to be corrected by one day. 0-Position Correction of 24-Hour Hand, Hour Hand, Minute Hand, and Second Hand: Pull the crown out to Position 2 in the chronograph [CHR] mode to correct each of the hands.  Press button (A) to align the second hand at the 0 seconds position. Pressing button (A) causes the second hand to advance by one second each time it is pressed. Pressing button (A) continuously causes the second hand to advance continuously  Turn the crown to set the 24-hour hand at the 24:00 position, and the hour and minute hands at the 0-position (12:00 position). Turning the crown by one revolution to the right causes the 24-hour hand, the hour hand, and the minute hand to move forward (clockwise). Turning the crown by one revolution to the left causes the 24-hour hand, the hour hand, and the minute hand to move backward (counter-clockwise). Turning the crown continuously by two or more revolutions causes each hand to advance continuously. When stopping the hands while they are advancing continuously, turn the crown by one revolution to the right or left. When the continuous advance of the hands is not stopped manually, they stop automatically after advancing by 12 hours.

Note: After returning the crown to the normal position, correctly reset the time and date in the time/calendar (TME) mode. In addition, reset the other modes as well before using the watch.

Setting the Time and Date [Setting the Time]

1. Turn the crown to align the mode hand at the time/calendar [TME] mode.

2. Pull the crown out to Position 2 (time correction position).

   • When the crown is pulled out to Position 2, the second hand rapidly advances to the 0 seconds position and stops.
     Notes:

   • When the second hand does not stop at the 0 seconds position, reset the 0- position (base position) in the “0-Position Correction Mode”.

   • If the crown is pulled out to Position 2 when the date is changing, the date stops changing at that time, and after the second hand rapidly advances to

   • the 0 seconds position, resumes changing until the date has finished changing.

3. Turn the crown to set the time.
   (1) Turning the crown by one revolution to the right causes the 24-hour hand, the hour hand, and the minute hand to move forward (clockwise).
   (2) Turning the crown by one revolution to the left causes the 24-hour hand, the hour hand, and the minute hand to move backward (counter-clockwise). Turning the crown continuously by two or more revolutions causes each
   hand to advance continuously. When stopping the hands while they are advancing continuously, turn the crown by one revolution to the right or left. When the continuous advance of the hands is not stopped manually, they stop automatically after advancing by 12 hours.  During the time correction, the date does not change even if the hands pass 12:00 AM. Refer to the section on “Setting the Date” for the procedure for

4. Return the crown to the normal position in synchronization with a telephone time signal or another time service.

[Setting the Date]
The calendar function used by this watch is based on a 31-day month. The date must be changed manually from the last day of the current month to the first day of the next month by operating the crown in months having less than 31 days.

1. Turn the crown to switch the watch to the time/calendar [TME] mode.

2. Pull the crown out to Position 1 (date correction position).

3. Turn the crown to the left to set the date.
   (1) Turning the crown to the left causes the function hand to make four revolutions and the date to be corrected by one day. The date is corrected one day at a time. The date will not change continuously even if the crown is turned continuously. When correcting the date by several days, first check that correction of the date by one day has been completed, and then turn the crown again to correct the date by an additional day until the date is corrected for the desired number of days.

4.  Always make sure to return the crown to the normal position after correcting the date.

[When Date is not in Center of Calendar Window]

When the date display has shifted from the center of the calendar window as a result of the watch having been subjected to a strong impact or other reason, properly center the date in the calendar window in the chronograph mode.

1. Turn the crown to switch the watch to the chronograph [CHR] mode.
2. Pull the crown out to Position 1.
3. Pressing button (A) causes the function hand and date to move slightly. Press button (A) several times until the number of the date is located in the center of the calendar window. After setting the date, press button (A) several times until the function hand reaches the 0 position (12:00 position).
4. Always make sure to return the crown to the normal position after correcting.

Using the Chronograph
The chronograph is able to measure time up to a maximum of 59 minutes and 59.95 seconds in a 1/20th second unit, after which it resets to 0 seconds.

[Explanation of Hands During Chronograph Measurement]

• When the crown is turned and the mode hand is set to the chronograph [CHR] mode, the second hand, and function hand are rapidly advanced to the 0 position (12:00 position), and the watch enters the chronograph mode.
• Second hand: Switches to chronograph seconds.
• The second-hand advances rapidly and makes one revolution only when starting at 0 seconds, after which it moves in 1-second increments to measure chronograph seconds.
• Function hand: Switches to either chronograph minutes or chronograph 1/20th seconds.
• Moves in 1-minute increments to measure chronograph minutes.
• When button (B) is pressed when the chronograph is stopped, the function hand switches to 1/20th seconds during the time button (B) is pressed.
• 24-hour hand, hour hand, minute hand:
• Continue to display the current time when the watch has been switched from the time/calendar mode.
• Continue to display the alarm set time when the watch has been switched from the alarm mode.

[Chronograph Measurement]

1. Turn the crown to set the mode hand to the chronograph [CHR] mode.
2. Press button (A) to start and stop the chronograph. A confirmation tone is heard whenever button (A) is pressed.
3. Continuously pressing the button (A) when the chronograph is stopped causes the chronograph second hand and chronograph minute hand to be reset to the 0- position (12:00 position).

Using Alarm 1 and Alarm 2
With the exception of the alarm tone, the procedure for setting the alarm and other operating procedures are the same for Alarm 1 and Alarm 2. The alarm function uses a 24-hour clock. Once the alarm has been set, the alarm sounds for 15
seconds when the set time is reached once a day.

Setting the Alarm Time]

1. Turn the crown to set the mode hand to the Alarm 1 [AL-1] or Alarm 2 [AL-2] mode. Second hand: Moves rapidly to the ON position (42 seconds) or OFF position (38 seconds).  24-hour hand, hour hand, minute hand: Move to the previously set alarm time.  Function hand: Stops at the 0-position.
2. Pull the crown out to Position 2 (alarm setting position). The alarm setting is turned ON automatically.
3. Turn the crown to set the alarm time. (1) Turning the crown by one revolution to the right causes the 24-hour hand, the hour hand, and the minute hand to move forward (clockwise). Turning the crown by one revolution to the left causes the 24-hour hand, the hour hand, and the minute hand to move backward (counter-clockwise).
4. Turning the crown continuously by two or more revolutions causes each hand to advance continuously. When stopping the hands while they are advancing continuously, turn the crown by one revolution to the right or left. When the continuous advance of the hands is not stopped manually, they stop automatically after advancing by 12 hours.
5. Set the alarm while making sure not to mistake AM and PM by referring to the 24-hour hand.
6. Return the crown to the normal position after setting the alarm time.

[Switching Alarm ON and OFF]
The alarm is switched ON and OFF each time button (A) is pressed when the crown is pulled out to Position 1 or Position 2 in the alarm mode.

[Alarm Tone Monitor]
When button (A) is pressed with the crown in the normal position in the alarm mode, the alarm tone sounds for as long as button (A) is pressed.

[Stopping the Alarm Tone]
Press either button (A) or (B) to stop the alarm tone while it is sounding.

All-Reset
This watch may not function properly as a result of being subjected to the effects of static electricity, strong impact, and so forth. When this happens, perform the All-Reset and Base Position Alignment procedures described below. If the base position alignment procedure is not performed after performing the all-reset procedure, the base positions of each hand will be incorrect, and the time will not be displayed correctly even if it has been set. In addition, failure to perform the base position alignment procedure will also prevent the alarm and chronograph modes from operating properly. When performing the all- reset procedure, first make sure that the watch is sufficiently charged and the second hand is moving in one-second increments. If the all-reset procedure is performed when the watch is insufficiently charged, it may not function properly or remain stopped following the reset procedure.

[All-Reset Procedure]

1. Turn the crown to set the mode hand to the chronograph [CHR] mode.
2. Pull the crown out to Position 2 (0-position correction mode). With the exception of the mode hand, each hand moves to its respective 0- position stored in memory and stops. (A hand may stop at a position other than the 12:00 position if its 0-position has shifted.)
3. Press buttons (A) and (B) simultaneously and then release Following a confirmation tone, each hand performs a demonstration movement in the order of the function hand, 24-hour hand, hour hand, minute hand, and second hand to indicate that the all-reset procedure is finished. This completes the all-reset procedure. Next, perform the base position alignment procedure.

Note : Do not press the crown to the normal position until the base alignment the procedure has finished following the all-reset procedure.

[Base Position Alignment Following All-Reset]

1. Press button (A) to align the second hand at the 0 seconds position (12:00 position).  Pressing button (A) advances the second hand by one second each time it is pressed. Continuously pressing the button (A) causes the function hand to advance continuously.

2. Turn the crown to set the 24-hour hand at the 24:00 position, and the hour and minute hands at the 0-position (12:00 position). Turning the crown by one revolution to the right causes the 24-hour hand, the hour hand, and the minute hand to move forward (clockwise). Turning the crown by one revolution to the left causes the 24-hour hand, hour hand, and minute hand to move backward (counter-clockwise). Turning the crown continuously by two or more revolutions causes each hand to advance continuously. When stopping the hands while they are advancing continuously, turn the crown by one revolution to the right or left. When the continuous advance of the hands is not stopped manually, they stop automatically after advancing by 12 hours.

3. Push in the crown to Position 1.

4. Press button (A) to set the function hand at the 0-position immediately after the date has changed (12:00 position).

5.  Pressing button (A) advances the function hand by one second each time it is pressed. Continuously pressing a button (A) causes the function hand to advance continuously. The date changes by one day when the function hand completes four revolutions.
   Note
   Turning the crown by one revolution to the left causes the function hand to advance continuously (make four revolutions) and the date to be corrected by one day.

6. After returning the crown to the normal position, correctly reset the time and date in the time/calendar (TME) mode. In addition, reset the other modes as well before using the watch.
