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 also equipped with

numerous functions including a 24 hour display and a chronograph function capable of

timing for up to 30 minutes in 1 second units.

2. Before Using

This watch is a solar-powered watch. Please fully charge the watch before using by

exposing it to light by referring to “5. General Reference for Charging Times”.

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 5 months without additional

charging.

To use this watch comfortably, make sure to charge it before it stops running

completely. Since there is no risk of overcharging no matter how much the watch is

charged (Over Charge Prevention Feature), it is recommended that the watch be charged

every day.

The second hand begins 2-second interval movement when the watch is charged by

allowing light to shine on the solar cell. However, since the watch has stopped as a result

of being insufficiently charged, the time is incorrect. Sufficiently charge the watch until the

second hand begins 1-second interval movement and then reset the time before using.

[Insufficient Charge Warning Feature]

Switches from 1-second interval movement (normal movement) to 2-second interval

movement

When the capacity of the secondary battery becomes low

as a result of light not shining on the solar cell, the

second hand switches from 1-second interval movement

(normal movement) to 2-second interval movement.

Although the watch continues to run normally at this

time, the watch ends up stopping if it remains

insufficiently charged for about 5 days after the start of

2-second interval movement. Sufficiently charge the

watch by exposing to light so that the second hand

returns to 1-second interval movement.

Notes:

• When chronograph timing is in progress, timing is interrupted and the chronograph

second hand is reset to the 0 seconds position.

• The chronograph minute hand stops at any arbitrary position. Press button (B) to

return to the 0 minutes position.

[Quick Start Feature]

When light (approx. 500 lx) shines on the solar cell after the watch has stopped as a

result of being insufficiently charged, the second hand begins 2-second interval

movement and the watch starts to run after about 10 seconds (the time until the watch

starts to run varies according to the model). However, please note that the watch will

end up stopping again if the solar cell is blocked from the light since the watch will

again become insufficiently charged.

[When Watch has Stopped due to Insufficient Charging]

When the capacity of the secondary battery has been depleted as a result of light not

shining on the solar cell, the watch becomes insufficiently charged and stops. When

light shines on the solar cell, the Quick Start Feature is activated and the second hand

begins 2-second interval movement. Sufficiently charge the watch by exposing to light

until the second hand returns to 1-second interval movement.

Note:

• Even though the watch starts to run, since the watch has previously stopped as a

result of being insufficiently charged, the time is incorrect. Reset the time before

using the watch.

[Over Charge Prevention Feature]

When the secondary battery becomes fully charged as result of light shining into the

watch dial (solar cell), the over charge prevention feature is activated automatically to

prevent the battery from being charged further. This prevents the performance of the

solar cell and secondary battery from deteriorating no matter how much the watch is

charged, and lets you expose the watch to light without worrying about overcharging.

12 13

6. Solar-Powered Watch Handling

Precautions

[Try to keep the watch charged at all times.]

Please note that if you frequently wear long sleeves, the watch can easily become

insufficiently charged because of being hidden and not exposed to light. When you take

the watch off, try to place in as bright a location as possible so that it will always be

charged and continue to run properly at all times.

Charging Precautions

• Avoid charging the watch at high temperatures (about 60°C / 140°F or higher) since

allowing the watch to reach a high temperature during charging can cause a

malfunction.

Examples:

• Charging by placing the watch too close to a light source that may become hot

such as an incandescent lamp or halogen lamp, or charging by placing the watch

on an automobile dashboard that can easily reach a high temperature.

• When charging the watch with an incandescent lamp, halogen lamp or other light

source that may reach a high temperature, always make sure to place the watch at

least 50 cm (20 in) away from the light source to prevent the watch from reaching

a high temperature.

Handling of Secondary Battery

• Never attempt to remove the secondary battery from the watch.

• If the secondary battery must unavoidably be removed, store it out of the reach of

small children to prevent accidental swallowing.

• If the secondary battery should happen to be swallowed, consult a physician

immediately and seek medical attention.

14 15

Only Use the Specified Secondary Battery

• Never use a secondary battery other than the genuine secondary battery used in this

watch. Even if another type of secondary battery is installed in the watch, the watch

structure does not permit its operation. In cases in which a different secondary

battery such as a silver battery is forcibly installed in the watch and charged,

overcharging may occur that will eventually cause the secondary battery to rupture.

This can result in the risk of the watch being damaged or injury to the wearer.

• When the secondary battery is replaced, always make sure to use the specified

secondary battery.

7. Replacing the Secondary Battery

Unlike ordinary silver batteries, the secondary battery used in this watch does not have

to be periodically replaced due to repeated charging and discharging.

8. Setting the Time and Date

If the crown of your watch is of the screw-lock type, operate the crown after first

loosening the screw locking mechanism by turning the crown to the left. When finished

operating the crown, turn the crown to the right while pushing in after having returned it

to the normal position and tighten securely.

[Setting the Time]

1. Pull the crown out to the time correction

position when the second hand reaches the

0 seconds position.

2. Turn the crown to set the time.

• The 24 hour hand moves in coordination

with the hour hand. Pay attention to AM

and PM when setting the time.

3. Securely push in the crown to the normal

position in synchronization with a

telephone or other time service.

16 17

After first stopping the second hand at the 0 seconds position, advance the minute hand

4-5 minutes past the correct time and then turn it back to the correct time. Then push in

the crown in synchronization with a telephone or other time service to accurately set the

time.

[Setting the Date]

1. Pull the crown out the date correction

position.

2. Turn the crown to the right to set the date.

• Nothing will happen if the crown is turned

to the left.

• If the date is set when the time on the watch

is between about 9:00 PM and 1:00 AM, the

date will not change on the following day.

If this happens, reset the date after

temporarily moving the hands to a time

outside the above time period.

• The date operates based on a 31-day month. It is therefore necessary to correct the

date by operating the crown to the first day of the following month in months with

less than 31 days (months with 30 days and February).

• The date changes around 12:00 AM.

3. Once the date has finished being set, return the crown to the normal position.

9. Using the Chronograph

* When using the chronograph, begin timing after first making sure that the chronograph

minute hand has returned to the 00 minutes position.

* If the chronograph minute hand is not at the 00 minutes position, slowly press button

(B) until it returns to the 00 minutes position.

[Chronograph Timing]

This chronograph measures and displays time up to 30 minutes in 1 second units. Each

of the chronograph hands stop when 30 minutes has elapsed.
