1. Your Watch
iAutomatic reception function: Every morning at 2 a.m. and 4 a.m. the watch
will automatically receive the radio wave and adjust the time.
However, if reception is successful at 2 a.m., automatic reception will not be
performed at 4 a.m.
iOn demand reception function: The radio waves can be received at any time
of the day to adjust the time.
* Not possible when the radio wave is interrupted
iEco-Drive function: This solar powered Eco-Drive watch is equipped with a
solar power function for powering the watch by converting light energy into
electric energy. The watch incorporates a power saving function that reduces the
electrical power consumption when the watch face is not exposed to light.
iTime difference adjustment function: The watch incorporates a convenient
time difference adjustment function (±27 hours).
A simple method is available for changing to the local time if you are going to
an area in a different time zone.
2. Operating the Crown
There are two models available for the crown: normal and screw lock.
<Operating the Screw Lock Crown>
<Moving the Hands Continuously>
When the crown is pulled out to the position 1
and quickly turned to the left or right (more than 2
clicks), the hands will rotate continuously.
To stop the continuous movement of the hands,
turn the crown to the left or right by one click.
* A gentle “click” can be felt by the fingertips.
• Turn the crown
to the left.
Using the side of your finger, quickly
turn the crown by two or more clicks.

Before using the watch, check that the hands are aligned with
“0”, similar to when setting weighing scales
iThe reference position may become misaligned when the
watch is exposed to strong magnetism, static electricity or
impacts.
Even if radio waves are received, the correct time will not be
indicated unless the watch hands are aligned to the correct
reference position. Check that the hands are properly aligned
with “0”.
Examples of magnetic products that can affect the watch.
• Health products (for example, medical necklaces and waist bands that have
magnetic fields)
• Refrigerators (magnetic part of the door)
• Electromagnetic cookers
• Bags (with magnet fasteners)
• Mobile phones (speaker part)
Keep the watch away from items similar to those above.

5. For Best Reception
There are three kinds of reception: automatic reception, on demand reception,
and recovery automatic reception. When the radio wave has been properly
received, your watch will automatically adjust the time. When reception is
complete, each of the hands will move either clockwise or counterclockwise to
the received time.
Remove the watch from your wrist and
place on a stable surface near a window
where the radio wave can be easily received,
pointing the 9:00 position in the direction of
the radio wave transmitter.
Do not move the watch during reception.
• Reception may be difficult due to the surroundings or metal shielding.
When inside a building, place the watch as close to a window as possible for good
reception.
• Radio wave reception may be difficult during the hours around sunrise and sunset. Avoid
attempting to receive radio waves during these times.

6. Poor Reception Areas
It may be difficult to properly receive the radio waves under certain environmental
conditions or in areas susceptible to radio noise.

jExtremely hot or cold
locations
jNear high-tension electrical
lines, railway overhead wires
or communication facilities
jInside vehicles, including
cars, trains and aero planes
jNear TVs, refrigerators,
computers, fax machines and
other electrical equipment or
office appliances
jNear cellular phones
that are in use
jInside reinforced concrete
buildings
Between tall buildings or
mountains, or underground
Radio Wave Reception
2. Press the lower right button (A) for more than 2
seconds and release it when the second hand stops
at the RX position.
3. When reception is complete, the second hand will
leave the RX position and return to normal
movement.
Referring to “Confirming the Reception Status”
(p.128), check the reception status.
Recovery Automatic Reception
iIf the watch stops due to insufficient charging, expose
the watch to sunlight to recharge it. When the watch
is recharged sufficiently, it will automatically receive
the radio wave once. Please remember to keep the
watch charged to prevent this situation from occurring.
jIf the lower right button (A) is pressed for more than 2 seconds during reception,
the reception will be cancelled and the hands will return to their normal movement.

7. Receiving the Radio Waves
Automatic Reception
iPlace the watch in a stable location near a window where the radio wave can be
easily received with the 9:00 position pointing towards the transmitter. The watch
will receive the radio waves at 2 a.m. every day. If the radio wave cannot be
received at 2 a.m., it will try again automatically at 4 a.m.
On Demand Reception (Manual Reception)
Radio waves can be received at any time.
* Not possible when the radio wave is interrupted
Use this function when automatic reception is impossible due to changes in the
reception environment.
(Depending on the weather or noise conditions, reception can take up to 15
minutes.)
1. Remove the watch from your wrist and place on a stable surface near a window
where the radio wave can be easily received, pointing the 9:00 position in the
direction of the radio wave transmitter.
The second hand stops
at the RX position.
