. . .constant force escapement (!) impulsed through the hairspring, not directly to an impulse jewel on the balance? That's just wild. That it was done in a 7.5 second tourbillon just adds to the tastiness, even if it IS tempermental. I'd just love to hear more about this particular watch, and about the desmodromic escapement, when and if you have time; and I'm just staggered that anyone would try for a constant force escapement at all these days- I was under the impression that constant force escapements had been more or less abandoned by the mid 19th century.
I wonder if some other constant force mechanism would have given the necessary uniform delivery of power- a remontoire or fusee? I expect there must be something in the design of the escapement itself that made him try for such an exotic design and would love to hear more about it.
Thanks very much- the most interesting post by far I've seen in months .
