I have a couple that are similar design but are chronographs. The Hanhart is a manual wind chronograph based on their 1939 design that they issued to the Luftwaffe. The modern one is not a flyback model like the original but looks almost identical, complete with asymetrical pushers.
The Aerowatch is the same Valjoux 7760 movement and very similar in appearence to the Hanhart. I actually bought it as a (relatively) inexpensive experiment to see if I wanted to spend the money on a Hanhart. Which I did, lol.
