Watch case dating.
Is there any publication that would show dated cases, making it easier to pair up era comparable movements to cases?

Mario, the good info Debbie provided is for cases from the about 1920's and later.

There are no known records for earlier cases but if you post a photo of what you are trying to match up perhaps someone here will be able to help.
