GUB Glashütte background information
The Glashütter Uhrenbetriebe (GUB) was formed in 1951 as a fusion of a number of nationalised watch, clock and instrument companies from in and around Glashütte, near the Czech border south of Dresden. As with other state-owned conglomerates in East Germany, the Glashütter Uhrenbetrieb was a "Volkseigene Betrieb" (VEB) which translates more or less a "People's Company". The full name was VEB Glashütter Uhrenbetriebe GUB, later "VEB Uhrenwerk Glashütte im VEB Kombinat Mikroelektronik".
The companies combined into GUB included: VEB Mechanik Lange & Söhne (which was the nationalised A. Lange & Söhne), UROFA, UFAG and VEB Messtechnik (Mühle & Sohn, which was integrated in 1980). The process of concentration continued up to 1985.
Following the reunification of Germany, VEB Glashütter Uhrenbetriebe was re-privatised by the Treuhandanstalt, an organisation set up to take control of the many thousand VEBs and either privatise or close them. After privatisation, the company became Glasshütter Uhrenbetrieb GmbH (GmbH is the equivalent of a Private Limited Company).
The new company used the Kaliber GUB 10 - 30 movement family, which had been developed during the GDR period, as well as other movements inherited from VEB Glasütter Uhrenbetriebe. Swiss ETA movements were also used. Watches were produced under the brand names 'GUB' and 'Glashütte Original' (signature: "Glashütte original Germany" or "Glashütte Spezimat Germany").
Privatisation was completed in November 1994, with the brands 'Glashütte Original' and 'Union' being used. In 1997, a spin-off company Union Uhrenfabrik GmbH Glashütte was created for the 'Union' brand. Walter Lange, grandson of Alfred, with the backing of the IWC company, restored the A. Lange & Sohne brand, producing their own movements and elevating the brand to the lofty heights it occupies today.
Watches were labeled GUB until 1967, from 1967 onwards they were signed Glashütte. The 70.1 was a very common movement and came in three grades; standard, upgraded with a golden screw balance and the top version was a chronometer. In total 388,800 were produced from 1960-1971. The caliber 74 (internally known as the 06-25) was a very famous movement, the date version was the caliber 75 (GUB 06-26). Both movements were produced in masses from 1964 to 1979/1980, and approximately 280 different models were available. The annual output of cal. 74/75 watches was about 260,000. From 1964 to 1980 1,858,466 watches with cal. 75 were delivered. In the same period 1,857,966 watches with ca. 74 and 6,526 ebauches were sold. Cases were gold or chrome plated, with 24 different cases encompassing the whole model range.
In the early 1990s, the fall of the Berlin Wall led to the privatization of GUB and its constituent brands. A. Lange & Söhne and Glashütte Original were both resurrected and now are part of Richemont Group and Swatch Group, respectively.
