Junghans serial numbers, last update: 29.10.2019

Junghans
My Junghans pocket watch serial number hypothesis.

There are several ways to use serial numbers in production: You can give each caliber its own serial number, or one uses only a sequential serial number, but gives the individual calibers separate number ranges. The calibers were always made dependent on demand. Junghans may have used both types of serial numbers throughout the history of the company. Up to now I have not seen any two digit serial numbers, wonder if Junghans started with the number "1" or maybe "100".
However, today there are no more documents on how the individual calibers were numbered by Junghans and to what extent they were made. And that's why Junghans does not allow calibers to be dated via the serial number.

On this site I write down the lowest and highest serial number of the movements and dedication engraving dates. If you have a Junghans pocket watch movement with lower or higher number or one with an engraved date please send me a picture.
