The karrusel is a feature similar to the tourbillon, but with the carriage driven
by the third wheel, not the forth wheel. Like the tourbillon it was designed to
eliminate errors of timekeeping in the vertical positions. It consists of a rotating
carriage or cage carrying all the parts of the escapement,
with the balance in the center. The karrusel mechanism is stronger and
less delicate than the tourbillon. This mechanism was invented by
Bonniksen in England in 1893.
This particular watch was entered in a timekeeping trial at the Kew Observatory
and was awarded a Class A certificate.
