■Receiving the radio signal
There are three ways to receive the radio signal.
This watch also incorporates a function to check last radio reception results.
→pages 14 and 15
Reception method Explanations
Automatic reception Receives the signal at 2:00 a.m. every day. If reception is unsuccessful,
the watch tries to receive at 3:00 a.m. and 4:00 a.m.
On demand
reception
Receive the signal manually when you want to adjust the time
and date. →page 24
Recovery automatic
reception
Receives the signal automatically after charging when the watch
stops due to insufficient charge.
• These reception operations take place only when the crown is in the closed
position 0and the watch is not moved.
• When the watch is in a low power state (second hand moving in two
second intervals), radio reception will not be attempted.
• Radio signal reception cannot be deactivated.
• Even when this watch receives a radio signal successfully, the accuracy of
the displayed time will be dependent on the reception environment and
internal processing.
• If the watch is not able to receive the signal, it will operate normally within
an accuracy range of ±15 seconds per month.
■During radio reception:
Remove the watch and place it on a stable surface
where it can receive the signal better, such as next to
a window.
• The reception antenna is located at the 6:00
position of the watch. Place the watch with the 6:00
position facing toward the station.
• While the watch is receiving radio signals (the second
hand indicates RX, H, M, or L), do not move the
watch as a successful update will not be acheived.

■Note on the radio signal
This watch receives the radio signal from the two signal stations located in
U.S.A. or Germany and automatically adjusts the time and date.
The receivable signal stations are listed as follows:
Signal stations Kind of the radio signal
Fort Collins station, Denver, Colorado State, U.S.A. WWVB
Mainflingen station, southeast Frankfurt, Germany DCF77

Notes on the radio signal reception

■Poor reception areas
It may be difficult to receive the radio signal properly under certain
environmental conditions or in areas susceptible to radio noise.
• Extremely hot or cold locations
• Inside vehicles
• Near electrical equipment or
office appliances
• Near high-tension
electrical lines, railway
overhead wires or
communication facilities
• Inside reinforced concrete
buildings, between tall
buildings, mountains, or
underground
• Near mobile phones that
are in use
■When signal reception is poor
Radio signal reception may be affected by the surrounding environment.
High-tension wires nearby or windows containing wire meshes make it
difficult to receive radio signal. In this case, you should find another suitable
place considering the location of the transmitter station in your region.
Then, place the watch at a window facing to the station and attempt manual
reception. →pages 24 and 25
If the window contains wire screens, open the window or change the
location of the watch.

4. To set the alternate time:
• Rotate the crown clockwise to advance the time in one hour increments.
• Rotate the crown counterclockwise to decrement the time in one hour increments.
• Pressing in releasing the lower right button (A) will advance the time in 15-minute
increments. Note: the time will not decrement in 15 minute increments.
• Be sure to set the correct AM or PM time by referring to the 24-hour indicator at the

Some areas observe Daylight Saving Time.
• Daylight Saving Time rules will vary depending on the country or region
within a country.
When the watch receives a successful radio signal update for the 5 cities, the
Daylight Saving Time setting is automatically updated, provided the user
has not manually turned OFF overridden the Daylight Saving Time setting.
If you live in an area that does not receive a radio signal, you will need to
update the Daylight Saving Time setting manually. →Page 30
■Checking the daylight savings time setting
While the watch is in the time display mode or A-TM
mode and the crown is set at position 0, perform
the following steps.
1. Press and release the upper right button (B).
The second hand moves and points to the current
setting for daylight savings time (ON or OFF).
2. Press and release the upper right button (B).
The current time display mode is resumed.
• Even if the button is not pressed, the current time display mode is
resumed automatically after about 10 seconds.

●Precautions for setting the daylight savings time to ON/OFF
When manually changing the Daylight Saving Time from OFF to ON to OFF, this
engages the manual override built into the watch. This manual override precludes
Daylight Saving Time from being automatically adjusted during the radio signal update.
If this function is not desired, the only way to cancel the manual override is to do the all
reset and 0-Positioning outlined. →page 54
During the Daylight Saving Time season
■ If you live in an area that does not observe Daylight Saving Time
Change the daylight savings time setting to OFF manually. Then, as long
as the city is selected, the setting remains OFF and the watch ignores the
daylight savings time update direction included in the radio signal.
●Sharing of daylight savings time setting
• The Daylight Saving Time / standard time is shared by multiple cities and regions
within the range of each transmitter station (Germany or U.S.A.). Whenever radio
signal is received from each station, the setting is updated automatically.
• If you manually set the watch to the standard time in a city, the watch will
always indicate the standard time for that city without synchronizing with other
cities.

This watch has a rechargeable cell which is charged by exposing the dial to
light such as direct sunlight or fluorescent lamps.
For optimal performance, be sure to keep your watch charged at all times. When
not wearing your watch, place it near a window or other light source to ensure
the dial receives light sufficient for charging.
In addition, to use this watch comfortably, follow the instructions below.
• Expose the watch with the dial facing towards direct outdoors sunlight
(not through a window) for five to six hours at least once a month.
• Before storing the watch in a dark place for an extended period of
time, be sure to charge it fully.

• When the battery is fully charged, the overcharge protection function stops the charging so
that the watch performance and secondary battery are not adversely affected by overcharge.
Your watch will run for approximately 10 months from a full charge or up to
1.5 years with the power save feature engaged (based on a full charge).
After the second hand starts moving once every two seconds, it will last for
approximately 3 days.
Recharging your watch
• When the watch is regularly covered with long sleeves, it may not be
charged sufficiently. Try to keep the watch exposed to light sufficient for
charging.
• Do not charge the watch at a high temperature (about 60˚C/140˚F or higher).
Recharging your watch
