Zenitissimo
Peril of owning outstanding book by Mr. Manfred Rössler
is that one finds so many nice little gems inside
so when you see them in wild you just take AK47 and start shooting 

Another piece that unexpectedly fell into my palm or better on my wrist
As book says
"Men's wrist watch ca 1970, "Zenitissimo"
model, steel case,manual winding Caliber 1730.
Paired with some new cuff links
Very slim profile with correct crown

To be honest for today standards it wears very small on wrist more like ladies watch
but times they are a changing 

Cheers
