Need some help 1675 Root Beer

[Swaye]

Found a really nice 1675 Root Beer at my AD. They have a stunning 1675 Root Beer that they have done some work on - replaced crystal and did some Crown work. They have also told me it is a 3.4 M serial, which I think makes it a 73-74 roughly.

Additionally, they told me it appears to have a Rolex replaced bezel and dial (they called the dial a T SWISS T I believe), and likely has had hands replaced as well. It is a nipple dial, and looks almost dark copper. Simply stunning. They also state (and the appearance to me confirms) that they believe the dial and bezel were replaced quite awhile ago, as they look fantastic, but do have just a bit of age.

Biggest thing is it is on a TT Oyster bracelet with plenty of stretch. Great shape, but it is old. Their best guess (and they admitted it was a guess) is that it was probably overhauled by Rolex many years ago, replacing the dial, hands (likely), and the bezel. Possibly also got the Oyster bracelet then. But, and here is the big but, they said it is also very possible that the original AD swapped out a TT Jubilee for a TT Oyster at point of sale (said it happened a lot back in the 70s), so it is impossible to say for sure what bracelet this might have come with, or if this one is even possibly original.

It also has the box, papers, manuals and original bill of sale from 1976 (which seemed odd to me because it appears to be a 73-74 model).

At any rate, I will include a picture in the hopes that one of our experts here can give me some guidance on how to approach this. They are asking 14K, which seems like a lot to me, for a TT, but of course they maintain it is well priced because full set Rolexes in this condition from the mid-70s are hard to find, and that the dial, hands and bezel are all an older quality Rolex overhaul. And they swapped the crystal, but as an AD with service department that is not a huge value hit. I know a decent bit about modern Rolexes, but go to 4 digit stuff and I am a blank. I love the watch, and 73 is my birth year, which seems silly but somehow draws me to the watch even more.

I am not asking for anyone to tell me if I should or should not buy the watch, I just want to know if what they are saying seems accurate, or if this all seems off. I really trust the guy who I am working with, but I am just so out of my element on this old stuff I need a hand. It looks good and feels right to me, but because I am no expert I thought I should ask! Thanks in advance for any advice!

Questions for the experts:

1) Is it unusual to have a watch serialized for 1973 that first sold in 1976?

2) The watch did not look overpolished to me, but from the picture does it seem okay to you?

3) Is it relatively rare to get a full set from the mid-70's? I see these watches going for 10-12K other places (it's kind of all over the map actually - saw one for 21K with no box/papers in roughly the same shape - perhaps it is all original?), but in rougher shape and with no box/papers. Does it really add a large premium like this?

4) Do the dial, hands and bezel all seem correct for the year/model, and does it make sense or look right to say it is probably an old Rolex overhaul?

5) Oyster bracelet? Normal to have them swapped at purchase? Normal to have them swapped during an overhaul or during their life? Does it hurt the value any?

Anything else I might be missing that you think a neophyte vintage Rolex guy should know I'd appreciate hearing. I just do not want to blunder hard on my first vintage Rolex if i decide to pursue it. Thanks so much.
