Export Alpina Gruen Cartouche

Tue, 23 May 2023 14:54

Nothing too exciting, but I don't recall ever seeing an Alpina-Gruen with a solid gold Cincinnati case.  I knew that Gruen exported some gold filled cases to Alpina, but I thought the precious metal cases were all Swiss, mostly Weber.  It's kind of weird to see a German assay stamp on a Cincinnati case.  Anyway, posted here for posterity.

E. Gubelin Lucerne

Marked DG&S on the movement; Fri, 04 November 2022 17:17

Here is an interesting one currently on the swamp. We've always seen these Gubelin's and the relationship to the guilds but this one has the Gruen markings to go with it.
