I have a similar clock with serial number 58607 on the movement, below the AJK Kieninger logo. The movement has several hand-made parts and haas never been disassembled or cleaned until a year ago. The face and weights look very similar to yours, with hammered brass finish, with a circle of hammered flowers. The movement is standard bim-bam on 5 gongs. My guess on the age of the clock is 1920 - 30, but if anyone has any serial number information, I'd be most appreciative.
Unfortunately, no Kieninger clock is yet 100 years old, as they started in business only in 1912!
