The FHF 908 is a manual-winding mechanical movement produced by Fabrique d’Horlogerie de Fontainemelon (FHF), a major Swiss ébauche manufacturer known for supplying reliable calibers throughout the 20th century. The FHF 908 belongs to a family of compact, rectangular-shaped movements, designed specifically for ladies’ watches or slim unisex models, especially those produced during the mid to late 1900s.

This movement reflects the ongoing trend of the time toward thin, elegant wristwatches with simple two-hand timekeeping functions.
