Comments about the data
open face calibre
These pocketwatch calibres were made with 18.5 und 19'''.
There are various bridge layouts, two base plates with differing dial-feet positions, and two slightly differing setting-lever springs.
The assignment of such differences to the groups FHF 1 to 9 and the calibre FHF 2124 is just partially known. But comparing the according calibres gives an imagination.
FHF 1 to FHF 16 designate movement groups containing calibres of different dimensions; individual designations start with FHF 22.
Example, year: signature; shock device
ca. 1935: 8, Swiss Made, 15 Jewels- FHF 19 2124
(FHF 2124 19''')
