These are two interesting articles that delineate the evolution of watchmaking in Glashutte.
"During the GUB era, a large manufacturing building was constructed, in which all watchmaking activity was centralized. Today, after a major renovation, that building houses Glashütte Original."
Perhaps this was already clear to others, but I kept wondering what the physical relation between GO and the Soviet production was. So apparently the main building where Spezichron, Spezimat and the like were made is the same one where GO does production today.
