Comments about the data

Remarks
escapement and winding parts from Helvetia
differences not known between 110, 111
From Helvetia only one variant of this calibre is known, but from Cortebert several; probably another of them was modified by Helvetia exclusively for Dugena.

Example, year: signature; shock device
ca. 1960: *Helvetia*, Swiss Made, 17 Jewels - 3731; Incabloc
(Helvetia 120)
