The principle is to mount the balance and escapement in a rotating cage. The balance & escapement rotate around their common axis going through all positions to average out the errors, Tourbillon cages or platforms usually rotate once per minute but 4 minute and six minute tourbillons are also found. The Tourbillon complication is an extremely difficult accomplishment to achieve & generally demands a high premium. 100% original and in great condition.
