failed pressure test - advice? urgency?

[kinnick24]

I've been offered a Rolex Datejust and the current owner told me he had taken it to a authorized Rolex service center who informed him that the bezel is aftermarket and as a result the watch wont pass a pressure test, hence the watch is not waterproof. He went on to say that the only way to correct the problem would be to find an original bezel for this model of Rolex.

With that said..if I decide to purchase the Rolex and have no desire to take the watch into water...how big a problem is the failed pressure test? Is this an urgent matter to get serviced? What if I want to keep the aftermarket bezel on the watch?

thank you
