I have this pocket watch, that belonged to my grandfather's gandfather, for a long time and I had never given any importance, until recently that I became curious to know when it might be made, what is the brand,...
It works properly, but it has no inscription, except on the back cover, where yo can see FER'S PATENT, but I find no reference to that brand.
When opened, this is what's inside:
Sorry for the lighting of the photos, but with the back transparent cover, reflections can be seen because y need lights and shadows to enhance the inscriptions on the back cover.
After seeing the inside and compare it to other watches manufactured by Roskopf that have exactly the same machinery, I learned that the son was called Fritz-Edouard Roskopf (perhaps the FER inscription?), but still have not found any other with the same aspect.
Excuse for my english, but it is not my native language.
