•INSTRUCTION MANUAL

A.BEFORE USING

This watch is not powered by an ordinary battery, but by converting photo energy into electric energy.

Before using, expose to light and make sure the watch is fully charged.

Since it takes time to recharge the watch until it starts running again once it has stopped, try to make sure the watch is charged every day.

When the watch is stopped, the watch hands will begin to move when the watch is charged for about 5 hours in the case of the two-hand model or about 1 hour in the case of the three-hand model at 3000Lux (under a fluorescent light at a distance of about 20 cm (8 inch)).

A secondary battery is used in this watch to store electrical energy. This secondary battery is a clean energy battery which does not use any toxic substances such as mercury. Once fully charged, the two-hand model will continue to run for about 5 months, while the three-hand model will continue to run for about 2 months, without further charging.

To use this watch comfortably, make sure that the watch is always recharged before it stops.

There is no risk of overcharging this watch. (Overcharge prevention function is included.)

B. SETTING THE TIME

Setting the time

1.Pull the crown out to the time setting position (the second hand will stop when the crown is pulled out in the case of the three-hand model).

2.Turn the crown to set the time.

3.After setting the time, firmly push the crown back in to the normal position.

C. FUNCTIONS OF SOLAR POWERED WATCH

If the charge becomes insufficient, a warning function will be activated that causes the display to change as shown below.

Refer to the explanations of each function on the following page for further details.

Normal time		Insufficient charge

Three-Hand Model

(One second interval movement)

:Second hand moves once every second.

Two Hand Model

(20 second interval movement)

:Minute hand moves once every 20 seconds.

Three-Hand Model

(Two second interval movement)

: Second hand moves once every two seconds.

Insufficient Charge Warning Function

In the case of the two-hand model, the minute hand moves by one minute interval movement, and in the case of the three-hand model, the second hand moves by two second interval movement to indicate the insufficient charging. Although the watch keeps the correct time when this happens, the watch will stop after about 5 days in the case of the two-hand model or about one day in the case of the three-hand model, after the start of the one minute interval movement or two second interval movement. Recharge the watch by exposing to light. The watch will then begin to run normally again.

Time Setting Warning Function

Although the watch hands will begin to move when the watch is charged after stopping, since the time is incorrect, the minute hand will move by irregular one minute interval movement in the case of the two-hand model, or the second hand will move by irregular two second time interval movement in the case of the three-hand model to indicate that the time is incorrect. When this happens, fully charge the watch and reset the time. The watch will continue to run by the irregular interval movement until the time is reset even if fully charged.

interval movement]	interval movement]

Overcharge Prevention Feature

You can recharge without worry

Once the secondary battery is fully recharged, the overcharging prevention feature comes into operation and prevents over-recharging.

D. CARE AND HANDLING DURING CHARGING

Notes on use

Take care to charge your watch during use.

Please note that if you wear long sleeves, the watch can easily become insufficiently charged because it is hidden and not exposed to light.

•When you take the watch off, place it in as bright a place as possible, and it will always continue to run properly.

Notes on recharging

•Avoid recharging at high temperatures (over about 60 C/140 F), otherwise the watch will be damaged during recharging.

(eg) Charging the watch near a light source that easily becomes hot, such as an incandescent lamp or a halogen lamp.

Charging in a place that easily becomes hot such as a dashboard.

When you charge the watch by an incandescent lamp, take a distance about 50cm (20in) from the light source to prevent extremely high temperature.

E. REPLACING THE SECONDARY BATTERY

Unlike ordinary batteries, the secondary battery used in this watch doesn’t have to be periodically replaced due to repeated charging and discharging.

CAUTION

Never use another battery different from the secondary battery used in this watch.

The watch structure is so designed that a different kind of battery other than that specified cannot be used to operate it. In case a different battery such as a silver battery is used by some chance, there is a danger that it will be overcharged to burst, causing damage to the watch and even the human body.

F. TIME REQUIRED FOR CHARGING

Time required for recharging may vary according to the design (colour of the dial, etc.) and operating environment. The following table will serve you as a rough reference.

Full recharging time (Empty to full):The time for fully recharge from stopped.

One day usage: The time required for the watch to run for one day with one second interval movement for 20 seconds interval movement.

*The recharging time is the time when the watch is continuously exposed to radiation.
