Comments about the data

open face calibre
pin-lever escapement
ratchet on dial side, hidden crown mechanism with rocker bar
strange: cannon pinion and minute wheel between plates
Some slightly differing variants of this calibre are known.

The brand Haka (German pronunciation of HK) was shared by Haller and Kienzle. The production code consisting of two lower-case letters (here pf) is typical for Kienzle.

Example, year: signature; shock device
ca. 1930: pf
