Вот интервью Дюфура 2002 г.
Ближе к концу текста он рассказывает про то, как реставрируя репетиры, обнаружил, что 7 из 10 были сделаны на эбошах, произведенных в Vallee du Joux, и решил сделать свои часы. Прямого признания в том, что он скопировал калибр там нет, но мастер относится к такого рода заимствованиям абсолютно нормально. Он почерпнул вдохновение в старых часах.))
"It's mostly what I learn by restoring complicated watches. Every time I . . . I repaired hundreds of repeaters, mainly pocket watches. Every time is the same principle, minute repeater is not many ways to do it, it's always the same principle but everyone had a different way: a little thing, a little spring, a different shape. And by repairing 10 complicated watches from the years 1850 to 1920, I would say on 10, 7 were made in the Vallee du Joux. As a blank, ok? Not signed by people from the Vallee du Joux. No, they were signed by big brands: Patek, Vacheron or even by brands like Glashutte Uhren, Assman or Lange or the English people, the Smiths or J.W. Benson. The complications were made here, ok?
Now by seeing all that, first you start to recognize the maker. Could be a Piguet, could be Aubert. Sometimes you have little letters under a hammer, like a secret signature, you know? You can recognize by the shape. And this pushed me and one day I said, "Why not try to make watches again?" And besides my restoration work, it's what I did. The movement you saw (referring to his first Grand Sonnerie pocket watch movement). It's how I made my first movement. This was my engine. It's where I took inspiration.
Sometimes I see on the forum when people are asking "Why this shape?" or somebody say "Yeah, but the ratchet looks similar to an old Patek." Yeah, it's normal. Because I took inspiration from what was done in the Vallee du Joux. There is a school from this area. I don't want to make a movement like Lange & Sohne, because this is the German school, it's different. Or I don't want to make a J.W. Benson, because it's different. I make from the Vallee. And of course when people say, "Hey, the ratchet looks similar to a Patek", it's normal, because Patek used to buy their movements here."
