Aside from the inner diameter issue, DW really does make the best bezels for the Daytona (and the Tudor 7032, for that matter). I've had the chance to directly compare them with a genuine example, and the engraved fonts on the 300UPH bezel are a very close match. Unfortunately, DW's 200UPH bezel (which comes with the 6265) is not quite as nice--the unserifed 7s are a minor tell.
Also, the DW bezel is slightly off when viewed in profile. It is taller than the genuine and, consequently, the upper surface of the DW bezel is more steeply angled. Finally, the gen has a more rounded edge. I don't think that's due to polishing, as the one I examined was not in terrific shape.
