General information
External factors may cause damage to the seals, buttons and the
watch glass, which could lead to condensation inside the watch. We
therefore recommend having your watch inspected at regular inter-
vals by your Junghans specialist.
Other service work, such as changing batteries or strap repairs,
should also be carried out by your Junghans specialist. Your watch is
provided with a quality strap which has been tested several times on
our premises beforehand. Should you wish to change your strap, ple-
ase use a strap of equal quality, preferably an original Junghans
strap.
Use a dry or slightly moistened cloth to clean your watch and strap.
Attention: Do not use chemical detergents (e.g. benzene, paint thin-
ners). This could damage the surface.
