Based in the luxury watchmaking capital of La Chaux-de-Fonds in the Swiss Jura region, Arnold & Son watches pay homage to its original founder John Arnold, with whose name it shares. As a renowned watchmaker, Arnold produced some of the most accurate marine chronometers of the 18th century, establishing his career in Cornwall, England. One of his most significant contributions was the modern definition of the term chronometer, something that continues to be reflected in the contemporary collections of Arnold & Son watches and their in-house range of mechanical watch movements.
