In ‘60 and ‘70 Italy was one of the most important markets for Zenith. nowadays Zenith is not highly regarded here, or at least not as well known as other brands. it happens that someone finds an old Zenith at home and decides to sell it (and maybe it's an EL primero!). all my Zeniths come from their original owners (except the last one). then there are some stock funds (nos) but they are mostly Rainbow and sometimes De Luca. my A3736 was from an old watchmaker who had closed down years ago and had kept a few watches (mostly omega 70s). while for a rolex collector it is a dangerous land (many Franken or assembled), for a Zenith lover Italy is the peninsula of treasures ...i would have a nice chance for an a386 that has been in a drawer for 30 years but i ran out of budget, i am taking time to raise my finances.
for example Autavia, on the other hand, you don't even see them here with binoculars...
