"Carousel" watches Six-minute carousels are very rare. In fact, the speed of rotation is closer to that of tourbillions than of carousels. "Carousel" watches are a design by the Danish watchmaker B. Bonniksen, who registered the patent in 1892 in England. His intention was to create a compromise between the "expensive" tourbillon and a normal chronometer - and he actually achieved better results with his carousel than some of the tourbillons.
