Comments about the data

Not sure that the Aplina 765 is actually equivalent to the Bifora 812. The example movement is not signed, but is in a high grade Alpina watch, and regarding the strange dimensions it can't be a replacement. Moreover the Alpina 765 is the only tonneau calibre with unknown origin.

Example, year: signature; shock device
ca. 1935: U, 5
