The company W. Hoff & Fils was active as a watch manufacturer in La Chaux-de-Fonds around 1880. The company probably didn’t exist very long. At the time there was also the Gerome Hoff & Fils company in La Chaux-de-Fonds. There was also the watch manufacturer Jean Guillaume von Hoff (1808-1885) and Eugène von Hoff (1845-1889).
