Comments about the data

open face calibre
Breguet hairspring
Contemporarily with joining the Ebauches SA, FHF and Landeron merged around 1925, but remainded fairly independent. The production of the FHF 2124 was passed to Landeron in the 50s, and the Landeron 2124 appeared in registers since 1961 (Bestfit).

Example, year: signature; shock device
ca. 1955: Landeron 2124 - BG; Incabloc
