I have for sale an antique German travel pocket alarm clock

It is made in Germany. It is stamped on back:  PATENT MADE IN GERMANY
It is made of brass, with dome glass crystal on the front (please note there is a chip on the crystal)
Feels very solid, and has good heavy weight in the hand
The case can be opened by unscrewing the bezel on the front
The mechanical movement winds up, and runs for a while and then stops
The alarm also works

Approximate dimensions are:  1.75 x 1.75 x 1.75 inches

It is a well made, hard to find clock. I was not able to find another just like it
In good vintage condition overall

Thanks for looking!
