Actually, every decent Rolex rep I’ve seen has a threaded case tube. can’t speak for the indecent ones because I‘m not that kind of guy.
To the point, however, my VSF NTTD rep does indeed have a press-fit tube and, like many, it needs replacing.
While I believe the genuine Omega has a screw in tube, I know this only from others as I have only seen photos of the gen watch. Since I’ve never seen photos of the tube on the gen, I suspect the crappy tube problem is VSF’s and not Omega’s.
Other than a movement needlessly encumbered with decorative hardware*, I think the rep is good enough to warrant an upgrade. The VSF case set is quite solid so I’m willing to drill and tap mine to accommodate genuine parts once I can source them; however, if VSF ups their game and releases a rep NTTD without all the flaws, I may never fix mine and you will see it listed for cheap on the ”For Sale” forum.
*IMHO decorative hardware with a solid caseback has got to be the worst idea ever.
