Rolex Daytona 6239 advice/thoughts?

[W44NEG]

Hi all,

This week, I'm meeting somebody to look at purchasing their 6239. I don't have any pics to post so thought I would describe it from what I've seen.

It's a black dial model (silver subs) with a polished "300" bezel and a silver chrono seconds hand. The watch features a non-riveted bracelet and states "T SWISS T" between the bottom of the lower sub-dial, and above the 6 o'clock lumed marker.

The lugs looks nice and thick, and the bezel doesn't appear to have been over-polished. The watch is from somebody I know of and he's a collector, so I trust the buyer and the watch.

My main thoughts are therefore around such a large purchase. This would be my first major foray into the vintage Rolex world. I've owned 5513s, and nearly picked up a 6536 Sub at one point, but the Daytona is a watch that really gets my pulse racing. Hopefully this one was worth waiting for.

What are the overall views and opinions on the 6239? I know a 6240 is a bit more sought after, but I'm not that fussed myself, and anything with screw-down pushers either turns out to be too worn or just not to my liking in some way.

Any help/thoughts/advice/views/opinions no matter what they are would be great. I have books to help me out but after reading that Daytona parts were often changed to help slow sales, I don't know which literature to believe in terms of correct configurations anyway.
