Comments about the data

hunter calibre
Breguet hairspring
This calibre isn't listed in any common register. But Flume lists a Buser 19''' with equivalent plate layout (Fig.3), and Ronda mentions a Buser 19'''Nidor (brand of Buser), but both are about 6.5mm high. More commonly the calibres Buser 95 (open face) and 96 (hunter) are listed. They have a different layout (Fig.4), but about the same height. Therefore their data are partially adopted here.

Example, year: signature; shock device
1-2) ca. 1930: Esta***
3) 1947: old data sheet
4) 1949: old data sheet

Not for Sale!
