My information request to the Deutsches Uhrenmuseum Glashütte/Sa resulted in:
The restored movement fit originally in a watchcase made of Gold 750, with "a-goutte-catches", form Lucia, label ALS, a hunter-case 102 gram heavy. A crystal dome protects the movement back.
The movement was designed for a hunter-case. Of course I have to follow this design.
I like first and foremost movements, their technics.
A watchcase of acrylic is transparent. The technic details remain visible.
