So i've been wondering, how many official companies printed dials for Universal Geneve. I've seen a few dials with no markings on the back, which i believe are made by UG? On others, you got SINGER, which made dials for a bunch of watch companies. I believe i've also seen A.L. stamped on the back of some UG dials.

Are there any information on whom printed dials for UG?

 

Is there anyone that has nabbed any leftover dials from Universal’s US operations? (Id like to get a 1948 Sugar Bowl dial)

 

Does a marking on a dial back indicate a (blankl) dial maker or a dial printer?

 

This thread has examples of various dial manufacturer's marks:

I believe Stern made dials for UG before. Read it from an auction lot history piece
