The clock based on the Junghans logo was made between 1890-1900. 
The mechanics of the clock, like the time and the alarm functions, are functional. 
Unfortunately, it only works for a short time and stops after a few minutes of operation. 
Unfortunately, I am not an expert in cleaning such clocks, so I did not touch it. 
I'm sure it will be fully functional after a little cleaning or adjusting. 
However, its operation can still be tested and seen, I don't think it is necessary for it to show the exact time. 
On the dial of the watch, the grain of the wood shows a face-like image. 
This is probably the result of a carefully selected raw material.
