Story: European discovery of New Zealand

Chronometer, c. 1820

Chronometer, c. 1820

Accurate timekeeping, used to calculate longitude, was essential for precise navigation and map making. James Cook could not have found his way so easily around the Pacific, or made such accurate charts, without the improvements in ships’ chronometers made in the 18th century. Although this chronometer was made 50 years after Cook’s voyages, it is a good example of the type of instrument he would have used.
