Comments about the data

open face calibre
pin-lever escapement
ratchet on dial side, hidden crown mechanism with rocker bar
in catalogs listed as Kaiser 8 or Kaiser 38/0
The similarities between Kaiser 8 (38), Kienzle 16-46, and to certain extent Würthner 19.5''' is surely no accident. Nothing is known about a cooperation, but likely tools were passed from one to the other.

38/0: 0 jewels, pin lever, pointed staff
38/10: 10 jewels, pin lever, pivoted staff
38/15: 15 jewels, pallet lever, pivoted staff, double roller
manufacturing process modifications:
W8: 0 jewels, pin lever, pointed staff
probably further variants were made this way

Example, year: signature; shock device
1962: 2 62, West Germany
