The FHF 57 is a manual-winding mechanical movement developed by Fabrique d’Horlogerie de Fontainemelon (FHF). As part of FHF’s broad range of small, reliable calibers, the FHF 57 was designed primarily for ladies’ watches and compact dress models, especially in the mid-20th century.

This caliber represents FHF’s dedication to producing minimalist, durable movements that could be used in a wide range of elegant and slim timepieces.
