4.3. ready for use
to ensure that your junghans watch is always ready for use, you should
avoid allowing its power reserves to run down. the watch regularly
checks to see if it still has sufficient battery power. if it no longer has
enough (e.g. because the battery has run out or the ambient tempera-
ture is too low, which impairs battery performance), the second hand
stops for 4 seconds and then quickly catches these 4 steps up. if the
battery does not recover (e.g. through the ambient temperature getting
better), you should take your watch to your authorised specialist dea-
ler to have the battery changed. alternatively, send it to the junghans
service centre.
please ensure that the battery is disposed of properly in accordance
with statutory regulations.
