A device for recording the epoch of an event. In its older form the astronomical chronograph includes a drum rotated at constant speed and a pen actuated by an electromagnet. A spiral line is traced on paper on the drum. Signals from a clock produce a set of time marks and signals made by an observer produce other marks, so that the epoch of the events observed can be determined.
Modem chronographs are of the digital printing type. In one form rotating type wheels carry numbers. In another form the time is accumulated electronically, and when a signal is given the output is printed by keys.

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.[1] 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.

Types
There are many types of chronographs.[1][2]
- Digital chronographs use a digital display for both timekeeping and stopwatch functions, either with separate displays or by switching modes on a single display.
- Analog-digital chronographs have a standard analog watch with permanent center seconds and a separate digital display that usually operates independently of the analog section. A fallback will reset to zero and then continue to run when the reset button is pushed while the stopwatch is running. In contrast, most mechanical chronographs will reset to zero only when the stopwatch is stopped.
