For over 200 years, the modern chronograph has been used in timepieces to further their functionality; a chronograph watch consists of a stopwatch and a display watch, allowing for an accurate recording of time. Initially thought to have been invented by French watchmaker Nicolas Mathieu Rieussec, it wasn't discovered until 2013 that the creator was in fact horologist Louis Moinet. In 1964, Japanese watchmaker, Seiko, launched the automatic chronograph, replacing self-winding versions; this new technology was further developed by luxury watch brands, such as TAG Heuer and Breitling. By the 1960s, the chronograph had also ventured into outer space, with the NASA crew of the first moon landing wearing the Omega 'Speedmaster' on their historical mission. Other famous examples of chronograph watches include the Rolex 'Daytona' - a favourite of iconic actor, Paul Newman - and the Breitling 'Navitimer', worn by astronaut Scott Carpenter during his orbit of the Earth in 1962.
