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.

Normal position

Second click

First click

Crown

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.

Fast Forward/Fast Reverse

After pulling out the crown to the first or second
click, 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.

The fast reverse operation speed is fixed
and cannot be changed.

Stopping Fast Forward/Fast Reverse

Rotate the crown in the direction opposite that
of the ongoing operation or press any button.

Note

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

Movement

Changing the day setting of the watch will also
cause the mode hand to move.

It can take anywhere from about 90 seconds
to three minutes for the day indicator to
change after timekeeping reaches
midnight. The mode hand moves as the day
indicator changes.

The day may not be indicated correctly while
the watch’s crown is pulled out.

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
the light by the sleeve of your clothing. Power
generation efficiency is reduced even when
the face of the watch is blocked only partially.

NO

YES

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.

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
