A chronograph is a wristwatch that incorporates both time and stopwatch functions. A chronograph watch can therefore be used to monitor periods of time lapsed, to calculate speed over a fixed or known distance or to measure the number of occurances of certain events during a fixed time period. The main types of chronograph watches include digital, analogue or Swiss automatic chronograph watches.
