Arnold & Son watches

Arnold & Son takes its name from John Arnold (1736–1799), the English watchmaker who worked in London and produced marine and pocket chronometers. The present brand was relaunched in Switzerland in 1995 by The British Masters in Timekeeping.

Since 2010 Arnold & Son has belonged to the movement manufacturer La Joux-Perret in La Chaux-de-Fonds, and its calibres are developed and produced within that company. Citizen acquired La Joux-Perret's parent, Prothor Holding, in 2012. In November 2025 LVMH took a minority stake in La Joux-Perret, with Citizen remaining the majority owner.
