Everbody knows the Spezimatic movements from Glashütte, but not many people know its successor, the Spezichon caliber, which was produced between 1978 and 1985 only a few 100.000 times. With 28.800 bph and its rather small size, it was compareable to the popular swiss movements of that time. The most noteable difference was the sound of the selfwinding mechanism, which was by far more pleasant, than the sound of other more populuar movements. The drawback was, that the 11-26 is lacking a finetuning mechanism.
If the sources are correct, then the 11-26 was reworked after the end of its production and was revived as caliber 10-30 in 1993. And, as everybody knows, the 10-30 was pretty much reworked, too, and was the base for the Glashütte-Original Caliber 10-39. (Source: http://www.thepurists.com/brandjpg/go/calibers/cal39.html)
