Loosen
Crown
●Pulling Out and Pushing In the Crown
To perform a crown operation, pull it out to the
first or second click and then rotate it. Do not
pull the crown with too much force.
First click
Normal timekeeping
Second click
Important!
●To prevent loss of water resistance
and/or damage due to impact, be
sure to screw the crown in by rotating
it away from you as you push it in.
Screw in
●When pushing the crown back in,
take care not to apply too much
force.
●Fast Forward/Fast Reverse
After pulling out the crown, rotating it quickly
in succession in either direction will cause the
hands to move forward or back at high speed.
While the hands are moving forward at high
speed, quickly rotating the crown in
succession again will increase the speed even
further.
●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.
Hands and the Day Indicator
Movement
30
Mode hand
Day indicator
●Mode Hand and Day Indicator
Movement
Changing the day setting of the watch will also
cause the mode hand to move.
●Day
●It can take anywhere from about 15 to 30
seconds for the day indicator to change after
timekeeping reaches midnight. The mode
hand moves as the day indicator changes.
●The day indicator will not change while a
stopwatch time measurement operation is
in progress.
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.
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

●Checking the Charge Level
You can determine the watch’s current charge
level by checking the position of the
retrograde dial hand.

●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 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.

Note
●Actual charging time depends on the
local charging environment.
●Power Saving
Leaving the watch in a dark location for about
one hour between the hours of 10 p.m. and 6
a.m. will cause the second hand to stop, and
the watch to enter Level 1 power saving. If the
watch is left in this condition for six or seven
days, all hands will stop at 12 o’clock and the
watch will enter Level 2 power saving.
Level 1 :
Second hand stops to save power.
Level 2 :
The following operations are stopped to save
power: all hand movement (excluding the day
indicator), Bluetooth connection, and alarm
alerts.
Recovering from Power Saving Operation
Press any button or place the watch in a well-
lit area to recover from power saving.
Using Mobile Link with
a Mobile Phone
While there is a Bluetooth connection
between the watch and phone, the watch time
setting is adjusted automatically in
accordance with the phone’s time setting. You
can also change the watch’s time settings.
Note
●This function is available only while
CASIO WATCH+ is running on the

●Auto Summer Time Switching
When the watch is connected to a phone, it is
sent summer time period information for your
Home City. If there is a World Time City
specified with CASIO WATCH+, information
for that city will also be sent. If the CASIO

Mobile Link Precautions
●Legal Precautions
●This watch complies with or has received
approval under the radio laws of various
countries and geographical areas. Using
this watch in an area where it does not
comply with or has not received approval
under applicable radio laws may be a
criminal offense. For details, visit the CASIO
Website.
http://world.casio.com/ce/BLE/
●Use of this watch inside of aircraft is
restricted under the aviation laws of each
country. Be sure to follow the instructions of
airline personnel.
●Precautions when using Mobile Link
●When using this watch in combination with
a phone, keep the watch and phone close
to each other. A range of two meters is
recommended as a guideline, but the local
environment (walls, furniture, etc.), the
structure of a building, and other factors may
require a much closer range.
●This watch can be affected by other devices
(electrical devices, audio-visual equipment,
office equipment, etc.) In particular, it can be
affected by operation of a microwave oven.
The watch may not be able to communicate
normally with a phone if a microwave oven
is operating nearby. Conversely, this watch
may cause noise in radio reception and the
video image of a TV.
●Bluetooth of this watch uses the same
frequency band (2.4 GHz) as wireless LAN
devices, and use of such devices in close
proximity of this watch may result in radio
interference, slower communication speeds
and noise for the watch and the wireless
LAN device, or even communication failure.
●Stopping Radio Wave Emission by This
Watch
The watch is emitting radio waves whenever
the second hand is pointing to e (Bluetooth
connected) or “R” (Bluetooth connection
standby).
Even if the second hand is not pointing at e or
“R”, the watch will automatically attempt to
connect with a phone four times a day to adjust
its time settings.
When in a hospital, on an aircraft, or in any
other area where the use of radio waves is not
allowed, use the operations below to stop
radio wave generation.
●Disabling Auto Time Adjustment
Configure CASIO WATCH+ settings to
disable synchronization between the watch
and phone.
