Here, we have a very old Kienzle pin lever movement, which is not marked on the plates, but could be identified with the Flume Werksucher of 1947. There, the Kienzle 51 is measured with 12 lignes.
It has got a balance with pivot staff, which runs in four jewels and has got “virtual” screws. The balance drives a pin lever movement, which displays seconds (at “6”), hours and minutes.
