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.
