5513 accuracy vs. new rolexes

[tschiemer]

I am contemplating buying a vintage watch, specifically a 5513 and wonder about accuracy on these old watches. Do those of you with vintage subs find they get close to cosc accuracy, or am I anticipating too much from a vintage timepiece?

All the modern Rolexes I have purchased have always kept good time and I have never owned an older watch but am considering venturing into the vintage world.


Thanks for any replies.
