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.]]>Ephemerald2022-09-17T00:35:08-00:00Re: Caliber 515SS

yes, that's alpina's mark. but was it the german arm, that became dugena?
This symbol was also used for Alpina Gruen.

I'd assume that the ebauche was delivered to Alpina as well and probably by accident Gruen got an already Alpina marked base plate. Also possible that Alpina had cancelled an order while Gruen needed more movements and accepted the Alpina marked plates. At that time the two companies had long separated and did not work together at all.
Hi Bernd. Would you then know the Alpina equivalent calibre number? I'd really like to take a look at it.
Ok thanks for feedback. Your theories make sense. While I understand that Alpina and Gruen were not known to be connected in this period, I thought it could be possibility...but still this movement Dan is referencing still interest me.
Check this out, upon closer inspection, in fact there does seem to be some mark on my movement in almost the exact same spot as Dan's Alpina mark🤷♀️ Just thought that was interesting too

Several comments and old sales claim that these watches were made for Gruen by Yema. But I have yet to see any supporting evidence or solid proof of that. ]]>Ephemerald2022-09-23T18:26:46-00:00Re: Caliber 515SS

No hint on the case maker at all.

Thanks for the feedback and data. One company that I am considering is LIP montres. They have a known Gruen connection from 30's. They made stainless cases in 60's. They also used this Jeambrun ebauche 26D extensively, as D26. Other similarities as well such as outside caseback stamps.

If it ever existed in series volumes. I was not able to find an Alpina or Dugena equivalent yet.]]>Barney Green2022-09-26T19:59:01-00:00Re: Caliber 515SS
