Keep your watch exposed to light!
Your watch runs on electrical power generated from light and stored by a rechargeable battery. To ensure stable operation, make sure that the watch is exposed to light as much as possible.
Tips on how to keep the battery charged
• Watch functions are disabled as remaining battery power drops. |
To ensure normal watch operation, be sure to expose the watch to |
light as much as possible. |

• Whenever you are not wearing the watch on your wrist, position it |
so the face (solar panel) is pointed in the direction of a source of |
bright light. |

Leave the watch under fluorescent lighting, near a window, etc.
•When wearing the watch, try to keep your sleeve from blocking its face (solar panel).
Charging efficiency is significantly reduced even if the face of the watch is only partially covered by your sleeve.
The Type B display has light colored figures on a dark background.
