They are beautiful and well finished. They out class many of the current in-house movements.
I find it interesting that 50-60 years ago, people were doing a much better job. Perhaps, everything was not so commercialised back then. May be, today, the brands emphasizes more on aesthetics rather than good finished movements as it is more time saving and more watches can be produced. That's why Dufour and Kari are the "rare breed".
