Looking to buy 1st Vintage Sub, need some advice

[cwmehring]

I’m looking at purchasing a vintage sub w/ date, model number 168000 with an R date code. The patina on the dial and bezel looks to be consistent with the age of the watch. What pit falls should I be looking for when buying something like this?
The edges of the shoulders still have the bevel. The lugs look good. The bracelet and end links are consistent with this release.

Any advice or assistance would be appreciated. Thank you!
