Time Interval

One-fifth of a second accuracy takes years to master. It is to this day one of the most sophisticated complications in the watchmaking mechanism and one of the hardest to perfect. Several construction types have been developed, but the most prestigious and spectacular one is the columnwheel chronograph.


A chronograph is a standard watch fitted with an auxiliary mechanism that measures and displays continuous or discontinuous spans of time without affecting the watch’s time-keeping functions. A center chronograph hand is started, stopped and restarted at will, then returned to zero by actioning one or more push-pieces. It is both useful in daily life and remarkably complex in technical terms.

Split Second Hand

Split second chronographs are fitted with an additional seconds hand that can be stopped in its tracks in order to measure an intermediate, or to maintain a reference time.
