What should I do ?

I want to buy my first watch, and u want it to be a good watch, my dream first watch would be a Rolex Milgauss, but that is for now a bit to expensive. I was thinking of buying a nice vintage watch, like a Rolex cellini or an old Cartier santos, but I don’t know if this would be as satisfying as buying the Milgauss.

What would you guys do ?
