Bought a nice 1984 34mm Tudor Prince Oyster Date for the wife but the Twinlock crown has zero threads to lock-down.
While looking for a replacement crown and tube there seems to be multiple Rolex equivalent case references.
May I ask for a couple of definite Rolex case cross-references before ordering please?

Any thoughts/feedback on using Cousin's generic tube part no. C8359 rather than shelling out for a Rolex 24-5300.0 tube, if C8359 is the right one?

Thanks for any input.
