Nothing is known about when, why and how many have been bought by Junghans?
There is sometimes a two-digit number on the back lid of the Junghans silver pocket watch cases which I have no
explanation for. I could not yet get any information about it and all publications do not talk about this number.
These numbers do not match the movement and seem to have a completely different meaning.
Seen numbers: 34, 36, 40, 42, 50, 60, 70, 95
To get more inside into this I have started to note down also which movement is in a so numbered case.
34 - J32, J33
42 - J17
60 - J9, J16, J33
70 - J13, J15
