Notes
open face calibre
bimetallic screw balance (example uncut)
option: Breguet hairspring
FHF ran several factories in Fontainemelon, and one was named after the founders Fabrique Robert. The calibres produced there are recorded in few registers (pretty poor and contradictionary) under names like Font Robert, FF Robert, FHF Robert.
An ad of R. Vogt & Cie. in Biel from 1920 shows this movement as calibre moderne Vogt 1/2 plat, although with flat hairspring.
