On this site I'm collecting technical data about the Junghans pocket watch movements. Last update 13.02.2016
The data are derived from Berger, Flume, Engelkemper, Jacob and Junghans books and catalogs,
and pictures I saw on the internet.
Any more information and hints are most welcome.
- J47G, J48G, J49G, the G indicates a new click spring assembly. The old assembly on the J47a, J47b, J48, J49 are still to find in the 1937 catalog.
- J47, J48, J49, the suffix /1 means that a seperate escapement wheel cock is used. I assume that these watches are made from 1938 or later.
- J5, J10, J36 are Alarm pocket watches. They can be identified easily. On the J5, 21''', the bell ist attached with two srews.
On the J10, 19''', the bell is attached with three screws. The J36, 19.5''', has only one pusher.
