Rattrapante - a chronograph with two center seconds hands, the extra hand runs concurrently with the main chronograph hand but can be stopped independently then made to catch up with the running chronograph. Thus called the "Split Seconds hand" which refers to two hands - a flyback (Rattrapante) hand and a regular chronograph hand. Both hands move together with the ability to time laps or multiple finishing times, the wearer can stop the flyback hand while the chronograph hand continues. This, in effect, splits the hand in two. The split seconds thus allows recording the successive or additional times of events that start together. Flyback Chronograph - retour-en-vol in French, a chronograph which restarts the instant it is brought back to zero without the need to stop, reset and restart the chronograph - it is particularly useful to pilots. Pressing the lower push-piece only, they can immediately reset the chronograph to time each successive leg of a search pattern. Without this facility they would have to use two push pieces to stop, return to zero and restart the chronograph while starting a new leg. 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 6 minute tourbillons are also found. The Tourbillon complication is an extremely difficult accomplishment to achieve and generally demands a high premium. 100% Authentic in like new condition.
