@ Olivax: look at the post of LHOOQ, he states that you need to trim the bezel with 0.5mm
Thanks LHOOQ for your reply, I've been reading more and more threads and it seems I'd need the Rolex 25-128 crystal, which is quite rare. I have been looking on the net an found some crazy prices on those crystals, however, I've been looking for some aftermarkets as well, this is what I found:

Movement has been bought!
An upgrade to the movement would be a gen Tudor bridge, however, this might be too hard to get. I've found a bridge by NDT, but clearly a rep? Check out the spelling mistake & font difference:
Gen:
Rep (not sure):
With a correct CAD file, wouldn't we be able to get some bridges produced?
