Aquired a Zenith Horodate

I bought a Horodate, i don’t know much about them except it’s the first Zenith Model to have a date function and that they were made with a 106 cal. In Besançon.
Previous owner bought it in 2007 in Lyon, France.
Anybody be able to tell me about this model (possible date?), or how many were made? I’ve seen guesses from a 200-500

Edit: Based off an earlier thread (link below) is the conclusion that these were made as a prototype project or would this be wrong conclusion?
