JUNGHANS – THE GERMAN WAT C H
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 enjoy this very special time-keeping instrument.
Yours,
Uhrenfabrik Junghans GmbH & Co. KG

General information
External influences can affect 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 fitted with a quality wrist strap that has under-
gone 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.
