Looking at my first vintage sub...

[tfrosst]

Hey everyone. I've been into watches for quite a while but only recently have I been able to start my collection. I've recently acquired an all original vintage speedmaster from the original owner and now have my sights set on a vintage sub.

I have been deciding between the 5512 and a 5513. What are the main differences and what should I really be watching out for?

I know these are getting more and more expensive but do you guys think I still might be able to pick one up for around $4000?
