Only watchmaker I've heard of in Germany is Roland Ranfft. He has an excellent website in both English and German.
I have never used him and cannot vouch for his work. Based on his description of movements and the care given to information in his site, I'm sure he knows what he is talking about. Here is his watch services pages.

His prices seem quite reasonable, especially by Euro standards.
