Mike,
I became aware of this brand in the 1990's. At that time, they were the darling of the watch enthusiast crowd because of the watches they made using things like exhibition backs, regulateur dials, etc. Matter of fact, Chronoswiss is generally regarded as being the first watch company to regularly use transparent case backs on a regular basis. In a few years, everybody had them.
Chronoswiss had an atelier in Munich where Gerd Lang employed a staff where, aside from the unimproved movements, the rest of the watch was made, though I'm sure other parts may have been imported, just like most other manufactures. The movements were largely modified Enicar and Valjoux movements. Production was always limited, usually between 5,000-7,000 watches per year.
It should be noted various German companies (Sinn, Stowa, Meistersinger, Tutima and others) used or still use Swiss movements. Before Lang sold the company to the Ebsteins, he opened an atelier in Bavaria in 2007 and employed a staff of 33, many of them watchmakers. When the company was sold, the atelier in Bavaria was closed, and everything moved to Switzerland.
In the '90's Chronoswiss and A. Lange and Sohne were regarded by watch enthusiasts as the best watches to come from that country, even though Lange had only been re-started a few years before. Glasshutte Original was an emerging brand, and today Lange and GO have attained a much larger stature in the watch world than they had 20-25 years ago. Most younger folks have never heard of Chronoswiss. Many who have do not know the significant role they had in the rebuilding of the German watch industry.
