Here’s one I hadn’t seen before, I presume one of the “white label” Gruens from the Alpina Gilde days. But could be earlier. Wasn’t sure where to post since it’s not listed in the Gruen material catalogs, but going with the Gruen database since it’s stamped as a Gruen. Pardon the front plate appearance—dial was glued on!!
19 ligne, 17 jewels.
Dr. Ranfft shows the Alpina 1721 is equivalent to the Moeris 19D, so lots of info/details there. His example is listed as 1925, but I think it’s maybe a later version, given the regulator.
He says this movement came in either Breguet or flat hairspring. This Gruen looks to be the flat variant.
My two caveats:
1) I'm wrong many times a day --just ask my wife!
2) Always seeking to learn more

Yes, this is a caliber from the early Gruen Alpina joint venture days. I have an Alpina 1722 which is the sister movement with 15 jewels which can be dated 1925 due to a dedication inscription in the watch.
Gruen and Alpina worked together already before they officially merged in Europe, definitely they cooperated in 1925 already. This might be one of the early tries of Gruen to sell watches in Europe at that time. Never seen one of these before, thanks a lot for sharing.
