Comments about the data

open face calibre
attention: left handed ratchet-wheel screw
After comparing the bridge layout with the hunter calibre Locarno 19''' one may suspect that similar to this was also self made by Lorarno. But from few movement catalogs only the hunter calibe is known.

Example, year: signature; shock device
ca. 1925: Swiss Made - AM (A. Michel)
