In the 1970s, two Ebauches SA subsidiaries, ETA and FHF, produced lines of movements that were designed to be interchangeable. These “Gabarit” (“Template” in English) movement families were ETA’s 2850 and FHF’s 400. Although newer in design than the ETA 2800 family, the ETA 2850 came too late and the project was cancelled after a short production period of just a few years.
