　　a watch that strikes the hours, quarters and minutes on gongs. The repeater is activated by a slide or button on the case edge. This is a highly complex achievement and increases the cost of the watch tremendously. Tourbillon

　　compensates for differences in rate caused by a watch adopting different positions. 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. The Tourbillon complication is an extremely difficult accomplishment to achieve and generally demands a high premium.
