Swiss watchmaking with English roots expressed in the collections Astronomy, Chronometry, World Time and Métiers d’arts

Arnold & Son eschews commonly expected conventions to create singular collections imbued with English heritage. It thus unites the exacting standards of Swiss watchmaking with a unique aesthetic. As a renowned watchmaker, John Arnold produced some of the most accurate marine chronometers of the 18th century. He won several awards from the Bureau des Longitudes, spurring him on in his research into timekeeping. He filed many patents as an inventor, including one for a compensation balance featuring a bimetallic balance spiral and another for a helical balance spring with terminal curves.
