Between the 18th and 19th century, Arnold & Son made a name for itself by creating some of the most precise marine chronometers of the epoch, which were used not just to tell the time, but as navigational instruments to determine longitude and sail safely from one location to another. Arnold & Son chronometers have taken part in extraordinary voyages, including James Cook voyages to the Pacific Ocean, as well as Sir John Franklin's ill-fated third and final expedition to the icy waters north of Canada in 1845.
