"Lange and Soehne is doing it with all their movements"
Yes, but most of them are much bigger and that helps a lot, to make things easier. Especially if we talk about 5950, 5951 or 5959, there we see a total different approach of very classical (Swiss) watchmaking at its best.
Also you have to look in the tiny details. A long time ago there was a dedicated comparison between Lange and PP movement finishing by Walt Odet. One has a more obviously beauty, at least to the non professionals.
I am travelling to SIHH and therefore more details now.
