specifications of Directive 1999/5/EC. A corresponding declaration of

4. 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
undergone multiple inspections in our factory. If, however, you decide
to change the strap, please fit a new one of the same quality, preferab-
ly an original Junghans wrist strap. Watch and wrist strap can be cle-
aned 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.
