Vintage Longines case

They look beautiful, despite the radioactive corrosion of the numbers on the dial.
Have you purchased them?

No, he wanted 2K for it 🤨

Hello! Following your advice, I was looking for 12.68z and finally found it.
Among many inadequate sellers (offering a non-working mechanism for $1,500, for example), I managed to find an offer for only $60.
So all that remains is to find a dial. (I'll pick the hands from my stock, I hope.)
I just don't understand, does the number start with 6 or 8... If it's the 8 millionth, then it's already from the 50s, it doesn't really match. But I have to choose from what I have.

May be ref 5796?

funny fact. In the spare parts with which the seller sent me this Longines case, there was also a dial. I tried it on for fun and it fit the movement. But strangely enough, it is not from this case))) it is larger than necessary in diameter and does not fit)
