JUNGHANS – THE GERMAN WATCH
Many congratulations on your purchase of a timepiece from
Junghans.
What began in 1861 with the founding of the firm in Schramberg
quickly developed into one of the most fascinating success stories
of the German watchmaking industry. While since that time the
demands made of watches may have changed, the Junghans
philosophy has always remained the same. Innovative flair and the
constant pursuit of precision right down to the smallest detail
define how the company works and thinks. You can see and sense
this in every watch that carries the Junghans name. For as diverse
as the Junghans range may be, it pursues one single goal: to
combine traditional craftsmanship with cutting-edge watch
technology and exciting design. That makes every watch with the
Junghans star unique.
We hope you will get great pleasure from this very special time-
keeping instrument.
Yours,
hrenfabrik Junghans GmbH & Co. KG

1. Radio technology – The most up-to-date way to keep time
5,000 years have passed since timekeeping began with sundials. In the inte-
rim there have been water clocks, the mechanical clocks of the 13th century
and quartz watches. Now we have the radio-controlled watch. A watch that
in good reception conditions never goes wrong and never has to be set. The
Junghans radio-controlled watch is absolutely precise, as it is linked by radio
frequency to the time control systems of the most accurate clocks in the
world. For Europe this is the Caesium Time Base at the Physikalisch-
Technischen Bun des anstalt in Braunschweig (Germany’s Institute of
Natural and Engineering Sciences). For North America it is the U.S.
Commerce Department’s Caesium Time Base at the National Institute of
Standards and Technology (NIST) in Boulder, Colorado. For Japan the
Ministry of Post and Telecommunication’s Caesium Time Base at the
Commercial Research Laboratory (CRL). All of these clocks are so accurate,
that they are expected to deviate by no more than 1 second in a million years.

1.1. Usable time signal transmitters
Your Junghans multi-frequency radio-controlled watch is capable of auto-
matic reception of time signals from the following transmitters:
– DCF77 in Mainflingen (Frankfurt am Main) for Europe
– WWVB in Fort Collins, Colorado (USA) for North America
– JJY40 on Mount Otakadoya (near Tokyo in the North East of the coun-
try) for Japan
– JJY60 on Mount Hagane (in the South West of Japan) for Japan, the
East Coast of China (Shanghai), South Korea and parts of Taiwan
With good reception, the Junghans multi-frequency radio-controlled watch
thus always shows the perfectly correct time within any of these four trans-
mission areas. The watch automatically synchronises itself overnight with
the DCF77, WWVB, JJY40 and JJY60 time signal transmitters. If reception fails
due to interference (e.g. stormy weather, electrical appliances or dimmer
switches), the Junghans multi-frequency radio-controlled watch will launch
renewed attempts to pick up the signal fully automatically the following
night. It is also possible to use a ‘transmitter call’ to synchronise the time
manually, for example at a location where reception conditions are better.
The latest time information received is stored in a time memory. This origi-
nal time continues to be kept using a high-precision 32kHz quartz move-
ment until the time is synchronised again. The radio-controlled time syn-
chronisation of your Junghans multi-frequency watch not only ensures an
always precise display of the time, but – given good reception – also takes
care of switching from winter to summer time, and vice versa, fully automa-
tically (at night). Please note that this does not apply to the USA’s WWVB
time signal trans mitter (see section 3 – Automatic time synchronisation). If
you travel to a country in a different time zone, the time adjustment facility
on your Junghans multi-frequency radio-controlled watch makes it easy to
switch to the appropriate local time.

2. Readiness for use
So that your watch is always ready for use, you should make sure that it does
not run low on power. The watch regularly checks to see if it has sufficient
battery power. If it no longer has enough (e.g. the battery has run out or the
ambient temperature is too low, which impairs battery performance), the
second hand stops at the 12 o’clock position. Whatever display is set at that
time on the LCD also then flashes, alternating with the letters [Lo]. In this
event, the seconds may also be shown on the LCD display. If the battery does
not recover (e.g. through an increase in the ambient temperature), you
should take the watch as soon as possible to your authorised specialist to
have the battery changed, or send it to the Junghans Service Centre to have
this done.
Battery type: CR 1620
Typical life: Approx. 2 years
Please note that manual time synchronisation is not possible when battery
power is low. Too much power would be needed.
Please ensure that the battery is disposed of properly in accordance with
statutory regulations.
3. Automatic time synchronisation
The daily, fully automatic time synchronisation takes place at night. While
the watch is receiving the signal, the second hand temporarily stops in the 3
o’clock position. During reception, the flashing bar in the LCD display shows
that the reception attempt is being made.
For the USA’s WWVB time signal transmitter the following specific feature
applies:
After a successful transmitter call or battery change (restart), your Junghans
multi-frequency radio-controlled watch always reads in Pacific Standard
Time. Due to the non-uniform changeover from summer to winter time and
the differing time zones in the individual US states, you are given the oppor-
tunity to adjust winter time, summer time and time zone settings (see 6.5)
manually. If, due to where you are, the time zone or summer / winter time
that you have set differs from PST, it is nevertheless retained during any sub-
sequent transmitter call or automatic synchronisation.

Following successful automatic synchronisation, the transmitter from
which the signal was picked up is permanently displayed. Thus if no signal
was picked up, no transmitter is displayed.
The date is always advanced automatically by the time signal. This process
also takes the 29th of February into account in leap years.
If all of the attempts at picking up a signal lead to no clear synchronisation,
the reception display is switched off (see also description of the ‘Reception
Display’ in section 6.3). On any such days without synchronisation, your
watch continues to run with the accuracy of a quartz timepiece, using the
internal time memory. As soon as the signal is picked up again successfully,
your watch is synchronised and the reception display is switched back on.
Recommendation: To ensure the best possible conditions for overnight
reception of the synchronisation signal, the watch should not be worn and,
if possible, not left near to any electrical appliances, mobile or cordless pho-
nes.
Important note:
When travelling into a different reception area (e.g. going from Germany to
Japan) no automatic time or thus transmitter synchronisation occurs until
the watch’s next attempt to pick up a signal. If the watch fails to pick up any
transmitter signal, please perform a manual transmitter call (see section 6.4
on manual synchronisation).
4. Functions
Please note: Depending on the model, your Junghans radio-controlled watch
is equipped with buttons or recessed correctors. Please use a suitable poin-
ted object to operate the recessed correctors.
Pusher lock (depending on model)
Depending on the model of your Junghans
radio-controlled watch you can block the T2
button. To do this, move the safety lever bet-
ween T1 and T2 downwards (in direction of
T2) until it engages and the red marking
becomes visible.
To restore all T2 functions, move the safety
lever upwards (in direction of T1).

Briefly press button T1 once again:
Display switches from the stopwatch function to 2nd time.
Hold down button T1 for > 3 seconds until what is shown in the LCD display
switches to [00]. Then briefly press the T2 button once. The language set-
ting display now appears.
After 9 seconds, the language display reverts automatically to showing the
date.
If power is low, the LCD display shows the seconds (flashing in alternation
with [Lo]). The second hand stops at the 12 o’clock position. By pressing T1,
however, you can still switch to date or 2nd time.
6. Description of watch functions and how to use them
6.1 Addition timer function
Press the T1 button repeatedly until you reach the [C0:00] display. The stop-
watch function is started and paused again by pressing the T2 button. The
stopwatch hand can be paused and started again any number of times. The
split times are added together. While the stopwatch function is active the
leading [C] flashes.

Pressing the T1 button resets the counter to [C0:00]. Please note: The reset
function can only be operated if the stopwatch function has first been paused.
6.2 2nd time
The 2nd time function gives you the option, independent of the analogue
time, to have another time shown on the LCD display (e.g. if you are on holi-
day in another time zone and want to see the time at home).
Press the T1 button repeatedly until the 2nd time is digitally displayed on the
LCD. The 2nd time can be set in 30-minute steps using the T2 button.
To do this, with the 2nd time displayed on the LCD, press the T2 button. The
2nd time starts to flash. Each press of the T2 button then lets you advance
the 2nd time by 30 minutes. If you hold down the T2 button, you can set the
2nd time in fast forward mode.
6.3 Reception display
The reception display shows you whether the watch has synchronised itself
with the signal from any of the four transmitters. This is shown by the posi-
tion of the bar in the LCD display. There are four possible displays:
DCF 77 (Europe)
WWVB (USA)
JJY 40 (Japan)
JJY 60 (Japan)
If the reception display is shown on the LCD, the watch has picked up the sig-
nal properly during the overnight automatic synchronisation. If all of the
reception times on the LCD display are switched off, this means that due to
poor reception conditions the watch was not able to synchronise automati-
cally. The next time that a signal is successfully picked up from one of the 4
transmitters, the reception display will be shown again.
6.4 Manual time synchronisation (transmitter calls)
Your Junghans multi-frequency radio-controlled watch can also be synchro-
nised manually, by performing what is called a ‘transmitter call’.
You do this by pressing the T1 button for over 3 seconds. The second hand
starts to move and positions itself at 12 o’clock. In parallel with this, the hour
and minute hands continue to show the current time. The reception phase
then starts. The reception display flashes on the LCD for the transmitter
with which synchronisation last took place and, instead of the date, the
seconds [00] are now digitally displayed. Please hold the watch still or put it
down while the signal is being received.
If synchronisation with the transmitter is not possible, all of the other trans-
mitters are then checked for possible reception of any of their signals. As
soon as a signal has been picked up, the digital seconds on the LCD display
start to advance. When the watch has picked up the signal, the hands auto-
matically set themselves to the transmitter’s local time and the second hand
advances to the current second. On the LCD the date is shown and the
transmitter that was successfully received is represented by the correspon-
ding reception display.
Should you be in a time zone different from that of the transmitter that the
watch picked up, then after one-off synchronisation you will need to set the
applicable local time for that location using the time zone setting function.

6.5 Setting the time zone
The Junghans multi-frequency radio-controlled watch can pick up the sig-
nals from the DCF77, WWVB, JJY40 and JJY60 transmitters. Within the trans-
mitter coverage areas your watch will thus reliably display summer or win-
ter time respectively (except for WWVB, see section 3 – Automatic time syn-
chronisation). If you travel to a country in another time zone, you can have
the local time there displayed as a 2nd time on the LCD display (for how to
set this, see section 2 – 2nd time) and/or adjust the analogue time shown to
the current local time.
You do this by pressing the T1 button, if necessary repeatedly, until the date
is shown on the LCD display. You then press the T2 button. The hour is now
also shown digitally on the LCD display (e.g.: [T12] for 12 noon). You adjust the
time zone, and thus also the hands, to the time in the zone in question by
pressing the T2 button again. You can use the digital hour display to help
you set the correct time. Repeatedly pressing the T2 button enables you to
set the hour in fast forward mode. You can set all time zones using the T2
button. As you do so, the date, if necessary, is also automatically adjusted.
If you want to set the 1st time, and thus the analogue time display, back
again to the original time, then please do so by following the same procedu-
re.
The time zones displayed when picking up the signal from the respective
transmitters are as follows:
Transmitter Time zone displayed
DCF77 (Europe) CET or CEST
WWVB (North America) Pacific Standard Time
JJY40 Japanese local time
JJY60 Japanese local time
If you wish, you can interrupt the manual synchronisation process as soon as
the second hand is in the 12 o’clock position.
To do so, briefly press the T1 button. The second hand then returns to the
original time.
Please note that manual synchronisation is not possible if battery power is
too low and the [Lo] symbol is showing on the LCD display.

6.6 Set language (day of the week display)
Your Junghans multi-frequency radio-controlled watch is shipped with the
language for the day of the week display set to German.
To change the day of week display to a different language, press the T1 but-
ton for over 3 seconds / until [00] is shown on the LCD display. If you then
briefly press the T2 button, [DE] for German is displayed. By pressing briefly
the T2 button again, you can change the date display to English. [En] for
English will now be showing on the LCD display.
In order to switch back and forth between the two languages, simply use the
T2 button.
You quit this menu by pressing the T1 button or automatically if you use
none of the buttons for 9 seconds.
7. Re-starting after changing battery
Following a change of battery, your watch will automatically begin a restart
routine. After you insert the battery, the hands will move to the 12 o’clock
position and your watch will start trying to pick up the time signal. As it does
so, the reception symbol of the transmitter it is currently trying to pick up
flashes. As soon as a signal is being received, the seconds on the LCD display
start to advance. After a few minutes, if the reception process has been suc-
cessful, the watch automatically sets itself to the correct transmitter time.
– On successful reception of the DCF77 transmitter, German local time is
shown, the reception display for the DCF77 is activated on the LCD and
the date is displayed with the day of the week in German.
– On successful reception of the WWVB transmitter, the Pacific time zone
is shown, the reception display for the WWVB is activated on the LCD and
the date is displayed with the day of the week in English.
– On successful reception of the JJY40 or JJY60 transmitter, Japanese local
time is shown, the reception display for the JJY40 or JJY60 is activated on
the LCD and the date is displayed with the day of the week in English.
If the watch goes 30 minutes without picking up a signal, the reception pro-
cess is aborted in order to save power. The hands remain in the 12 o’clock
position and 2 flashing dashes [--] are shown on the LCD display.
If you nevertheless want to use your watch, you are able to set the current
time manually. It then runs like a quartz watch. The procedure is described
in the next section, 7.1 – Manual start.
7.1 Manual start
After an unsuccessful restart (at least 30 minutes with no reception from
any transmitter), you can trigger the manual start routine. This can also be
done during the restart process.
After the hands have reached the 12 o’clock position in the restart routine,
please press button T1. The watch is now in manual start mode.
Manual start mode is indicated by the year, e.g. 2007 [2007], being display-
ed.
Each press of the T2 button moves the display forward a year. Holding down
the T2 button adjusts the year in fast forward mode. Once you have got to
the current year, this needs to be confirmed by briefly pressing the T1 button.

What is shown on the LCD display switches to the month setting, e.g. [M 01].
You again perform the setting via the T2 button. The month you want must
then again be confirmed by briefly pressing the T1 button.
Perform the following settings using the procedure described above:
– Set the date - what is shown on the LCD display switches to [D 01]
– Set the hour - what is shown on the LCD display switches to [00: ]
– Set the minute - what is shown on the LCD display switches to [ :00]
In order to get the seconds displayed correctly, please ensure that you always
set the watch to the next full minute and confirm the time at the 60th
second.
After you have set the minute and confirmed this by pressing button T1, the
hands of your radio-controlled watch then move to the time that you set.
The date is shown on the LCD display. A 2nd time can be set as normal.
If necessary, the programmed time can be corrected by holding down button
T2 for longer than 3 seconds.
Your watch is now in quartz mode and will not make any automatic
attempts to pick up a time signal. You can make a manual transmitter call,
however, at any time.
If you make a transmitter call while in quartz mode, then in addition to the
current seconds an [M] is displayed on the left. This indicates that the trans-
mitter call is being launched in quartz mode.
A successful transmitter call overwrites the manually set time and after-
wards your watch works as a radio-controlled watch.
8. General information
External influences can affect the watch’s waterproof qualities, which may
let in moisture. We therefore recommend that you have your watch regular-
ly inspected by your Junghans specialist. Other servicing tasks or wrist strap
repairs should also be done by your Junghans specialist. Your watch is fitted
with a quality wrist strap that has undergone multiple inspections in our
factory. If, however, you decide to change the strap, please fit a new one of
the same quality, preferably an original Junghans wrist strap. Watch and
wrist strap can be cleaned with a dry or slightly moistened cloth.
NB: Do not use che mical cleaners (e.g. benzine or paint thinners). These may
harm the surface.
