Using the Crown

Depending on the operation you want to
perform, pull out the crown to the first or
second click and then rotate it.
Important!
To prevent loss of water
resistance and/or damage due
to impact, be sure to push the
crown in to its normal position
after you are finished using it.
When pushing the crown back
in, take care not to apply too
much force.
After pulling out the crown, rotating it
quickly in succession in either direction
will start a fast forward or fast reverse
operation. While a fast forward operation
is in progress, quickly rotating the crown
in succession again will increase the
speed even further.
Rotate the crown in the direction
opposite that of the ongoing operation or
press any button.

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.
Fast Forward/Fast Reverse
The fast reverse operation speed is
fixed and cannot be changed.
Stopping Fast Forward/Fast

Note
If you do not perform any
operation for about two minutes
after pulling out the crown,
crown operations will
If that happens, push the crown
back in and then pull it out again.

Solar Charging

This watch uses a special
rechargeable (secondary) battery.
The watch’s battery will not charge if
the watch’s temperature is less than
approximately -10°C (14°F) or
greater than approximately 60°C
(140°F).
Over-discharge will occur if the
watch is not charged within
approximately three months after it
stops operation due to low battery
power. Charging may not be
possible after over-discharge
occurs.

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.
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.
A fully charged watch can
operate for approximately
seven months without further
charging. Watch operation will
stop approximately 20 days
after the battery goes low.
