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
light by the sleeve of your clothing. Power
generation efficiency is reduced even when
the face of the watch is blocked only partially.
NOYES
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.
ー 
On the dashboard of a vehicle
parked in the sun
ー 
Near an incandescent light bulb or
other source of heat
ー 
Under direct sunlight or in other hot
areas for long periods
Remaining Charge and Dead Battery
You can determine if the charge level is low by
checking the hand movement. Functions
become disabled as battery power goes low.
Important!
Should the battery go low or go dead,
expose the face (solar panel) to light as
soon as possible.
Note
Exposing the watch face to light after
the battery goes dead will cause the
second hand to revolve
counterclockwise until it stops at
second 57. This indicates charging
has started.
Low Battery Power
The second hand jumps at two-second
intervals.
