VEB Glashütter Uhrenbetriebe
By 1951, all of Glashütte’s watch production had been combined into a single company called VEB Glashütter Uhrenbetriebe, and there are a few rare examples of watches produced during these tumultuous years with confusing dial labels. Glashütte watches, although now mass-produced, were still well-regarded though. The Spezimatic and Spezichron watches from the ‘60s and ‘70s are still some of the coolest designs from the era, and they also founded the basis for what would become Glashütte Original. As time went on, the dream of German reunification edged closer to reality, and the process began in 1989. Released from state control in 1990, Glashütter Uhrenbetrieb GmbH became a legal entity holding much of the historic copyrights and trademarks, opening the door for other brands to return too. The 1990s and early 2000s witnessed a boom of resurrections such as A. Lange & Söhne, Union Glashütte, Mühle Glashütte, and Nomos Glashütte.
