Tudor 79190 advise needed

[Ligne]

Long time lurker but first time poster.....

I'm looking at a B6 serial Tudor Sub and would be very grateful if anyone could give a checklist to confirm originality, especially the below details;

Dial - matte dial, T Swiss made T
Crown - should it be Rolex or Tudor?
Bracelet - which bracelet ref and end links are correct?
Bezel insert - replacements easy to spot or identical to original without removing?

Any other advise would be much appreciated!

I have one, those are the items I would look for. Also, it should have a sapphire crystal. 9315 Tudor bracelet. Crown should be Rolex.
