Many thanks for a very well-written article, as always!
I would just like to add onepoint of view: Herr Nienaber also produces wonderful limited editions and unique pieces with vintage movements modified by himself and sometimes finished by Jochen Benzinger. As I write this I am wearing his wonderful 2002 limited edition with a PUW 1663, and you can find this beauty on his website:
