JUNGHANS – THE GERMAN WATCH
Many congratulations on your purchase of a timepiece from
Junghans.
What began in 1861 with the founding of the rm 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 air and
the constant pursuit of precision right down to the smallest
detail dene 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 enjoy this very special time-keeping instrument.
Yours,
Uhrenfabrik Junghans GmbH & Co. KG

Instructions for use
Important note:
Do not make any changes to the date between 08:00 p.m. and 02:00
a.m., as the date is automatically advanced by the movement during
this period and you could damage the date advance mechanism.
Winding up the watch
With the winder in position A, you can wind up the automatic move-
ment manually. At least 2 to 3 rotations of the winder are needed to
start the movement. It is better to wind it up completely. It is fully
wound up after c. 40 rotations of the winder, 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-locked winder,
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 winder into position C. That stops the watch movement.
To set your watch accurately to the second, it is best to stop the
movement as the second hand is passing the gure 60. You can
now position the minute hand precisely in line with the relevant
minute marker and set the desired time. Press the winder back into
position A to start the second hand.

month has less than 31 days, set the date manually to the rst day of
the following month.
Setting the week day (depending on model)

General information
External inuences can aect the watch’s waterproof qualities, which
may let in moisture. We therefore recommend that you have your
watch regularly inspected by your Junghans specialist. Other servicing
tasks or wrist strap repairs should also be done by your Junghans
specialist. Your watch is tted with a quality wrist strap that has
undergone multiple inspections in our factory. If, however, you decide
to change the strap, please t 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 chemical cleaners (e.g. benzine or paint thinners). These
may harm the surface.
