Solar Charging

What is solar charging?

This watch runs on power supplied from a
rechargeable (secondary) battery that is
charged by a solar panel. The solar panel is
integrated into the face of the watch, and
power is generated whenever the face is
exposed to light.

Charging the Watch

When you are not wearing the watch, put it in
a location where it is exposed to bright light.

While you are wearing the watch, make sure
that its face (solar panel) is not blocked from

by the sleeve of your clothing. Power

the light
generation efficiency is reduced even when
the face of the watch is blocked only partially.

●

When the watch connects with a
phone by Mobile Link, Home Time
City information

is obtained from the
phone. Such information is indicated
by a diamond mark (¿) to the left of

the city name.

●

This function can be used in any
mode.

●

While hands are shifted, watch
button operations are the same as
when hands are unshifted.

●

Changing to another mode returns
the hands to their normal positions.

Shifted hands will return to their

automatically while settings are
being configured. They move back
to their normal positions after
settings are complete.

Important!

●

Depending on light intensity and
local conditions, the watch may
become hot to the touch when
exposed to light for charging. Take
care to avoid burn injury after
charging. Also, avoid charging the
watch under high-temperature
conditions like the ones described
below.
