Perpetual Calendar- A complication showing the day, date, month and leap year cycle at the minimum. The watch will correctly adjust for short and long months as well as 29 days of February once every 4 years.
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 and 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 and generally demands a high premium.
