Dan,

I am sorry, but in my personal opinion the caliber Gruen caliber 615 and the Concord movement you linked do not share more than the size. I can't see a match in any aspect, I think that is what you later meant by it being a Glycine 80 caliber.
The Vertex movement may be a later generation of the same ebauche used for Gruen 615 though. There are many similarities, too bad that we cannot see the dial side.
But for none of the movements I can see a relation to Aegler.
BTW, the ebauche of cal. 615 has some features which make me think of Lavina as source, but I may be wrong here.


Gruen, Gruen, Gruen ist alles was ich habe... Gruen, Gruen, Gruen is all I have...(German folklore song)
