ENGLISH Congratulations on becoming the owner of an original Junghans!
Junghans watches are and always have been something special.
They have made watchmaking and design history. And we are
still doing so today. For the story of success that began in 1861 in
Schramberg in the Black Forest continues with each new model.
Present in every watch are the elements that make Junghans
special: style, passion, innovative spirit and precision right down
to the tiniest detail. Put another way: when traditional crafts-
manship, leading edge watch technology and classy design come
together, then it is a genuine Junghans. A watch for all those
who live their own style – and on that we can not do other than
congratulate you!

Important note:
Do not reset the date between 8pm and 2am since the movement
switches the date automatically during this period. To carry out fast
adjustment (pull crown to pos. B), rst set the weekday and then the
date.
Winding up the watch
With the crown in position A, you can wind up the automatic
movement manually. At least 2 to 3 rotations of the crown are nee-
ded to start the movement. It is better to wind it up completely. It is
fully wound up after approx. 40 rotations of the crown, as then the
maximum accuracy and its power reserve (even after the watch is put
down) will last for the maximum period.If your model has a screw-lo-
cked crown, this must be unscrewed by turning it to the left to start
your watch going. After you have set your watch, you should wear it,
so that the automatic winding system (via rotor movement) keeps it
constantly operational.

Setting the time
Pull the crown into position C. This stops the movement. You can now
set the required time. To achieve a time display that is as accurate as
possible, we recommend subsequently positioning the minute hand
in a backwards movement. This serves to minimise the degree of tol-
erance in the trains. Example: you wish to set the time as 10.10. Rotate
the minute hand clockwise until 10.20 is displayed, then set the time of
10.10 in anticlockwise direction.
Then move the crown back to position A.

Note for models with second hand: to set the time precisely we
recommend stopping the movement when the second hand is over
the 60.
Setting the date and weekday (quick date reset)
Pull the crown to position B. First adjust the weekday by rotating the
crown counter-clockwise. Then set the date by rotating the crown
clockwise. Please note that the date should not be reset between 8pm
and 2am as the movement switches the date automatically during this
period and you could otherwise damage the switching mechanism. If
the month has less than 31 days, set the date manually to the 1st day
of the following month.
Using the chronoscope
Starting time measurement:
You start the chronoscope by pressing the start-stop button (10).
Stopping time measurement:
You stop the chronoscope by pressing the start-stop button (10) again.
Reset:
Press the reset button (11). This returns all three of the stopwatch
hands to their starting position.
Adding measured times:
After measuring the rst time, you can add times together by pressing
the start-stop button again instead of the reset button. The chrono-
scope hands will then continue running from the stopped position.

The water resistance as prescribed by DIN is a design engineering
characteristic which is susceptible to external inuences such as shock,
uctuations in temperature, UV light and direct contact with cosmetics
and cleaning products (greases and acids). The “3–30 BAR” condition is
thus only applicable for brand new watches. We recommend having the
watch inspected at regular intervals.

General information
The water resistance of your watch can be aected by external inu-
ences, which can cause moisture to enter the watch. We therefore
recommend regular checkups by a Junghans specialist. Servicing and
bracelet repairs should also be carried out by an authorised Junghans
service partner.
Please avoid direct contact with alcohol containing perfumes, disin-
fectants and chemical cleaning detergents (e.g. petrol or paint thinner),
as this will shorten the life of the glass, gaskets and leather strap.
Your watch is equipped with a quality strap which has been tested
inhouse several times. If you would like to change your strap please
use a strap of the same quality, preferably an original strap. The watch
and leather straps can be cleaned with a dry or slightly damp cloth.
Metal bracelets should preferably be cleaned with a small brush and
soapy water.
