Junghans catalog 1923

Although we commenced watch manufacturing at a comparatively recent date our watches have already, owing to their high quality and reliability, gained a world-wide reputation. Our method is: Utmost precision in the production of all parts, ruthless removal and destruction of all parts which are found to be in the least faulty or inexact, assembling, examination and regulation by proved experts. This system ensures equal high quality of all our watches and absolute interchangeability of all parts.

Here are some hints how to separate some Junghans movements from themselfs.
 
Is it a J26 or a J31/J32?
As you can find J26, J31 and J32 movements without markings and as they look the same, there is this little hint, which can help you to determine if you have a J26 in hand or a J31/J32, without taking the watch apart.
Use a caliper and messuare carefully the distance between the top of the top plate and the top of the bottom plate. If more than 4 mm it is a J26. 
 
Another feature which distinguishes the J26 from a J31 and a J31 from a J32 are the amount of screws on the balance wheel.
J26 14 screws, J31 8 screws and the J32 has 16 screws.
