A chronograph is a timepiece or watch with both timekeeping and stopwatch functions. Pocket watch chronographs were produced as early as the 18th century but did not become popular until the 1820s. The term "chronograph" is often confused with the term "chronometer" which in some cases designates a watch that has received a precision certification. The Marine chronometer was an accurate timepiece used to enable celestial navigation.
