Swiss Watch Movement - FHF ST 96

The ST96 movement was used in a lot of watches before the Quartz revulotion and can be a "decent" work horse.

The FHF (Standard) caliber 96, a men’s size movement, which was used frequently, is a direct relative of the vintage FHF 67, althogh the shape and decoration of the bridges is much more modern.

The center second hand is driven directly; the ring balance does not have a long regulator arm, but a quick release mechanism for the hairspring regulator - a very useful detail for a service.

The FHF caliber 97 is a vintage Swiss made mechanical hand-wound movement with 17 jewels. FHF stands for Fabrique d’Horlogerie de Fontainemelon. FHF was founded by David Benguerel, Isaac Benguerel, François Humbert-Droz and Julien Humbert-Droz in 1793 and was one of the earliest ebauche movement factories. In 1925, it became part of Ebauche SA. FHF produced affordable caliber they called “Standard” movements until the 1980s. In 1985, FHF officially became part of modern day ETA.
