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 features including a 24 hour display and chronograph function that allows measurement of time in 1 second units up to 60 minutes.

2. Before Using

This watch is a solar-powered watch. Please fully charge the watch before using 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 five months without additional charging.

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 everyday.

4. 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.

8 8 8

[Normal Time Display]

[Insufficient Charging Warning Feature]

The second hand switches from 1-second interval movement to 2-second interval movement

[Stopped]

All hands stop moving

If insufficiently charged

If watch is continued to be used without charging

The watch hands resume 2-second interval movement when the watch is charged by exposing to light. However, the time is incorrect as a result of the watch having stopped due to being insufficiently charged. Sufficiently charge the watch until it resumes 1second interval movement and reset the time before use.

If 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 1-second interval movement to 2-second interval movement (insufficient charging warning feature). Although the watch continues to keep time accurately at this time, the watch stops after about 5 days have elapsed after the second hand has switched to 2-second interval movement. When this happens, charge the watch by exposing it to light until the second hand returns to 1-second interval movement.

Notes: • During chronograph

measurement, measurement stops and the chronograph second hand is reset to the 0 seconds position.

• The chronograph minute hand stops at any arbitrary position. Return it to the 0 minutes position by pressing button (B).

[Quick Start Feature]

If the watch has stopped as a result of being insufficiently charged, the second hand will begin 2-second interval movement and the watch will begin to run about 10 seconds after the watch is exposed to light (approx. 500 lx). (The time until the hands begin to move varies depending on the model.) Please note, however, that the watch will stop again if the watch is blocked from the light and is not sufficiently charged.

[When the Watch has Stopped due to Insufficient Charging]

When the capacity of the secondary battery decreases as a result of the solar cell not being exposed to light, the watch will stop due to being insufficiently charged. The Quick Start Feature will be activated and the hands will begin to move if the solar cell is exposed to light. Sufficiently charge the watch by exposing to light so that it returns to the normal time display (1-second interval movement). Note: • The time is incorrect when the watch has stopped as a result of being

insufficiently charged even if the watch starts to run. Reset the watch to the correct time before using.

[Overcharging Prevention Feature]

The overcharging prevention feature is activated when the secondary battery is fully charged so that it is not charged further.

5. General Reference for Charging Times

Recharging time varies according to the watch model (such as the color of the dial). The times in the table below should therefore only be used as a rough reference.

* Charging time refers to the amount of time during which the watch is continuously

exposed to light.
