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 numerous functions including a full-auto calendar that changes the date automatically (day, month and year change automatically through February 28, 2100 including leap years), a daily alarm function that can be set based on a 24hour clock, and a chronograph function that allows measurement of time in 1120 second units up to 59 minutes, 59.95 seconds.

3. BEFORE USING

This watch is a solar-powered watch. Before using this watch, expose its solar cell to light sufficiently to charge its rechargeable battery.

If this watch has stopped running because of insufficient charge of this rechargeable battery, recharge this battery by exposing the solar cell to strong light such as the sunlight.

A rechargeable battery is used in this watch to store electrical energy. This rechargeable 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 9 months without additional charging (when the power save feature is operating). This rechargeable battery is not a user replaceable item.

• Power Save Feature

When power generation stops as a result of light not shining on the solar cell during the time display or local time display, 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. If light (several tens of luxes) does not shine on the solar cell for continuous 15 seconds (this period depends on the design, however) and the second hand comes to the 12:00 position, the watch enters the power save mode.

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.

5. 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.

Regardless of the display of the watch at the time, when the watch becomes insufficiently charged, the watch changes to the time display and the second hand moves to the CHARGE position to inform the wearer that it is insufficiently charged. After the second hand moves to the CHARGE position, the watch changes to the time display in the order of the 24-hour hand, hour hand, minute hand and date wheel (function hand). Although the watch continues to keep time accurately at this time, the watch stops after about 5 days have elapsed (roughly 2 days in the case the hands have been moved to switch the time when the insufficient charging warning feature is activated).

When this happens, charge the watch by exposing to light so that it returns to one-second-interval movement. However, since the time is incorrect when the watch is exposed to light and changes to the insufficient charging warning display after it has stopped due to insufficient charging, set the time after sufficiently charging the watch.

Notes

• Chronograph measurement stops and the chronograph is reset even when measurement is in progress.

• The set time (time difference) is retained for the local time.

• The alarm will not sound even if it is set.

• Crown (mode switching) and button operations will not function.

When the watch is recharged by exposing to light after it has stopped, the second hand moves to the SET position to inform the wearer that the time is incorrect. Although the 24-hour hand, hour hand and minute hand will begin to move after the second hand moves to the SET position, since the time is incorrect, reset the time and date after sufficiently charging the watch.

Notes:

• Crown and button operations will not function except for time and calendar setting operations.

• When the crown is pulled out to position 2 (time correction position) in the time or date setting mode, the time setting warning feature is canceled. The second hand will remain stopped at the SET position unless the crown is pulled out to position 2 and the time is set.

In the case the watch has stopped due to

•

insufficient charging, a minimum of 30 minutes are required until the watch changes to the time setting warning display even if sufficiently exposed to light.

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

When power is no longer generated as a result of light not shining on the solar cell when the watch is in the time/calendar mode or local time mode, the second hand moves to the 0 seconds position and stops to save power by reducing current consumption.

The 24-hour hand, hour hand and minute hand continue to keep the correct time even though the second hand is stopped. Furthermore, the calendar is corrected in coordination with the 24-hour hand, hour hand and minute hand.

Note:

During the time the rechargeable 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 has temporarily become fully charged as a result of exposure to intense light.

During normal hand movement, when power generation is resumed after the second hand stops at the 0 seconds position, the second hand is rapidly advanced to the correct seconds and begins one-second interval movement. However, when the insufficient charging warning feature has been activated, the second hand moves to the CHARGE position and stops, and when the time setting warning feature has been activated, it moves to the SET position and stops. When the watch has stopped, the second hand moves to the STOP position and remains stopped.
