Solar Charging

A solar panel generates electrical power that charges a built-in (secondary) battery.

SpacerThe entire face is a solar panel, so power is generated when the face is exposed to

light. Keep the watch exposed to light as much as possible.Charging the Battery

Crown

When you are not wearing the watch, leave it where it is exposed to light. For stable operation, expose the watch to at least a half day of light per month.

When wearing the watch, try to keep your clothing from blocking its face (solar panel). Charging effi ciency is reduced signifi cantly even if the face is blocked only partially.

Charging Time to Recover from Dead Battery

Some water-resistant models (100 meters, 200 meters) have a screw-in crown. When you need to perform a crown operation, rotate it towards you to unscrew it. Then pull the crown out. Avoid applying undue force when pulling. The watch loses its water resistance while the crown is unscrewed. After performing a crown operation, fully screw the crown back in.

If your watch has a rotary bezel...

You can rotate the bezel to align its ▼ mark with the minute hand. Then you will be able to tell how much time has elapsed since aligning the ▼ mark.
