Missed this post but found it after czeching out some of my Gruen Industries watches bc of latest talk.

I found I have one of these 515ss from France, no Alpina mark like yours, that is curious! Was Alpina finishing these for Gruen? Also a Style 046. But I got interested in Jeambrun the ebauche maker, fascinating company, good start here.

They are clearly high quality watches. The case is stainless and also made in France. Man, I'd love to find out the casemaker. Any ideas?
My serial is 30148. It fits somewhere!
All in all it's kinda cool having an all French Gruen..Didn't realize I had one til today.
