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
the light by the sleeve of your clothing. Power
generation efficiency is reduced even when
the face of the watch is blocked only partially.
Day indicator
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
On the dashboard of a vehicle
parked in the sun
Near an incandescent light bulb or
other source of heat
Under direct sunlight or in other
hot areas for long periods
Checking the Charge Level
Enter the Timekeeping Mode.
Navigating Between Modes
Press (B).
This will cause the disk to show the current
charge level.
H: Good (high)
M: Good (medium)
L: Insufficient (low)
Press (B) or do not perform any operation
for one or two seconds to return to the
current time.
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.
Should battery go low or go dead,
expose the face (solar panel) to light
as soon as possible.
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.
