Split Second – 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. This watch is in new condition steal sealed from manufacturer and comes to you with original box and papers. (papers dated 2012)
