Junghans catalog 1937 text:

Bridge movement, semi-fIat, 15 jewels, flat hair spring, lever escapement with visible jewels, double safetv roller, gilt plates and bridges.

The J47e is a J47b with the second wheel pinion shortened for use in the pocket watch for blind people.

G indicates a new click spring assembly from 1934.

The suffix /1 means that a seperate escapement wheel bridge/cock is used.
I assume that these watches are made from 1938 or later.
