Vintage Junghans Repeat Mechanical Alarm Clock -Works Great

A vintage Junghans Repeat wind up mechanical alarm clock made in Germany back in the 1950s. It is made of metal with a black background and works very well (at the moment it is running a little fast but that can be adjusted using the lever in the rear). I believe that they call it "Repeat" as the alarm repeats itself; it rings, waits a few minutes and rings again. This repeats itself until the alarm is completely unwound or until the button on top is pushed down, though I had to push it twice. It is loud enough that the alarm scares me and my cat, Tiger, flees to the inside of my desk when it goes off. There is wear as in the pictures. It is 4" tall to the top of the button, 3 5/8" wide and 1 3/4" deep.
