D. Guide to Charging Time
The charging time varies according to the model (including the color of the watch face).
The following data should only be used as a guideline.
500 Indoor lighting
1,000 60 – 70 cm (24 – 28 in.) beneath a 30 W
fluorescent light
3,000 20 cm (8 in.) beneath a 30 W florescent light
10,000 Cloudy sky
100,000 Direct summer sunlight
* If the second hand is moving in 2-second intervals, refer to "Time for full charging" and fully charge.
For a 1-day movement charging time:
The charging time to run the watch for one day with normal movement.
Time for full charging:
The time for full charging after the watch has stopped due to an insufficient charging.
Note:
A fully charged battery will run the watch for about 6 months without further
charging. The watch will maintain its accuracy for about 2 and a half years when
running in the power saving mode.
Charge the watch every day, as it will take a long time to recharge it, as is indicated
in the table, when it stops due to an insufficient charging.
Furthermore, it is recommended to charge your watch by exposing to direct
sunlight for a long time once a month.
E. Handling the Solar Powered Watch
CAUTION Charging precautions
• Overheating while charging can cause the watch exterior to become discolored, the watch
to deform or the movement to be damaged.
• Do not charge the watch in a high-temperature environment (about 60°C/140°F or more).
Examples:
• Charging close to incandescent lighting, halogen lamps, or other lighting sources that
easily become hot.
• Charging on surfaces that can easily become hot, such as a car dashboard.
• When charging with incandescent lighting, halogen lamps, or other lighting sources that
easily become hot, place the watch at least 50 cm (20 in.) away from the source to avoid
overheating.
WARNING Handling the secondary battery
• Do not remove the secondary battery from the watch yourself, unless unavoidable.
If you must remove the battery, store it out of reach of children to avoid accidental
ingestion.
• If the secondary battery is ingested, consult a doctor immediately.
WARNING Changing the secondary battery
• Although the secondary battery should never need to be changed, in rare instances, the
watch may be unable to be charged due to a problem with the battery.
If a problem occurs, have the watch repaired as soon as possible.
* The charging time is based on continuous exposure.
