Famous last words:
"The difference between a tourbillon and a karrusel resides in the speed,with which, the cage rotates and the position of the balance. When the cage makes one revolution per minute and the balance is mounted coaxially with the cage - it is a tourbillon. Anything else is a karrusel." : Some-Horology-Author-Somewhere, I'm sure

Karrusel movement.......but not by Bonniksen
Apparently, Bonniksen invented his 'karrusel' in 1892, bypassing Breguet's patent for a fixed wheel and using a differential effect instead, to rotate the cage. There was no difference between Bonniksen's and Breguet's movements for timekeeping, so people only remember the earlier tourbillon.
If only someone would make a watch with a karrusel escapement, whose balance is mounted in the centre of a cage, which makes one revolution per minute.........
Would that karrusel be a "tourbillon" too, by definition?
Would it be better than a tourbillon, from a design/aesthetic viewpoint? (since no one has proven timekeeping is any better)
