I agree with flex about the insert, but with that dial (which looks nearly gen), I do not have the usual urge to give the watch a 2nd look because of a rep-looking dial.
Did ingod finally get the spacing of ROLEX correct? Can you shoot another pic with the hands away from the text?
Overall, it looks good, but I think you may need to soften the edges a bit more.
Only if it has an AR coating (the AR refracts the light). The cyclops on my TT GMTIIC has AR & it is the only part where the light refraction creates the rainbow effect
As Nanuq said
If you have a gen & aftermarket xtal of the same type under the same light, the gen should sparkle more. But basing authentication on light refraction is not a reliable path to follow.
Without a pic, it is impossible to say how much of a tell your zero risk leak mod is. What I can tell you is that if your mod looks like a working gen valve, it is not a tell. Otherwise, it is.
