Comments about the data

open face calibre
ratchet on dial side, crown mechanism with rocker bar
It is unknown whether the ebauches were made by AM or Felsa. However, many registers list primarily AM (e.g. Bestfit, Quickfit).

Example, year: signature; shock device
1936: Pat. D.R.P., Swiss Made, 15 Jewels - BR, Ebauches-SA logo from 1936 (TR in shield)
