The Fontainemelon 821-4 is a manual wind mechanical watch movement that was used around 1936. It features a cylinder escapement and an uncommon crown mechanism with a rocker bar, with the ratchet located on the back side. It is unclear if the presence of the completely functionless crown wheel is standard. Although there are some minor differences, the Fontainemelon 821-4 shares similarities with the A. Schild 278 movement.
The Fontainemelon 821-4 features the following functions:
