Comments about the data

Remarks
hunter calibre
The calibre shares balance, keyless works, and further parts with
763, 790-793 (17.5''')
4, 5, 8, 9 (18''')
15, 954, 955, 2709 (19''')
As all these calibres are poorly documented, and almost never with images, these facts are uncertain.

Example, year: signature; shock device
ca. 1930: 79, Ref.792, ZentRa 126 - 17971579

Not for Sale!
The movements presented in this caliber finder are not for sale. This is only a data sheet for identification and evaluation of the movement calibre, as well as for approximate dating.
