The following table shows you the charging times following complete 

discharge of the energy store. These charging times are dependent 

on the intensity of the light source. The guideline values stated in the 

table are for orientational use only. Please note that the design of the 

solar dial affects the charging time.

10. 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, 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.
