Arnold & Son: A Movement-First Watchmaker

Arnold & Son is more than just a name on a watch, it's a legacy of technological ingenuity, refined style, and mechanical art. The modern incarnation began in 1995, and through mergers, scandals, and reshuffles, emerged as a haute horological movement showcase.

Rooted in Innovation

 

 

 

John Arnold founded Arnold & Son in 1764. As a pioneering marine chronometer maker, he supplied instruments to the British Royal Navy, earning acclaim from the French Bureau des Longitudes. Arnold’s patents—for bimetallic compensation balances and helical balance springs—shaped the modern notion of the “chronometer”: a neutral-tested, precision timepiece. His developments laid the foundation for chronometer mass production in the 18th century, establishing Arnold & Son’s DNA as a brand built on technical mastery.

Rebirth with The British Masters

Fast forward to 1995: Les Monts S.A., later known as The British Masters, was founded in Switzerland by industry veterans including Eric Loth, Pierre-André Finazzi, Ernst Thomke, Max Imgruth, and Jean-Pierre Jaquet. Their goal was to revive the tradition of British watchmaking under names like Graham and Arnold & Son. The first collections launched in 1998, balancing historical inspiration with contemporary Swiss craftsmanship.

Strategic Integration with La Joux-Perret

Parallel to this revival, movement specialist Jaquet-Baume SA in La Chaux-de-Fonds was gaining prominence. After a rebranding in 2003, it became La Joux-Perret and continued supplying sophisticated calibers to brands including FP Journe, Hublot, and Girard-Perregaux. Importantly, in 2010, La Joux-Perret acquired Arnold & Son, bringing complete vertical integration: watchmaking, design, and movement manufacture under one roof.

Joining the Citizen Group Family

Citizen Watch Co. entered the story in 2012 by acquiring Prothor Holdings, including La Joux-Perret and Arnold & Son. While Citizen is known for advances in quartz and everyday watches, the acquisition brought serious mechanical-watch credentials to its portfolio. For Arnold & Son, it meant long-term backing and scale, without diluting its independent spirit.
