A chronometer is a timekeeper precise enough to be used as a portable time standard, usually in order to determine longitude by means of celestial navigation. In the world of watches, the term is also often attached to those tested and certified to meet certain precision standards. In Switzerland, only timepieces certified by the COSC may use the word Chronometer on them.
