Solar Charging

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

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.
