No worries. The gen crown sits low in the case and is not perfectly aligned with the crown guards, kind of like the crown on a gen AP Offshore Chrono. The reps seem to have done a good job duplicating this.
Also, for those of you that were concerned about the dark blue cabochon, Cartier uses blue spinel (not sapphire) in its steel watches (it uses sapphire in its precious metal watches). Their blue spinel usually has a very dark shade to it, similar to this:
Most of the cartier reps use cabochons that are too light in color--mimicking the cornflower blue of the sapphire cabochons. Having handled the gen 2018 Santos a bunch of times, everyone I saw had a dark blue spinel cabochon when viewed under indoor, jewelry store lighting. It's the same type of cabochon I had in my old franken Santos 100 XL--that I foolishly sold--which had a gen crown. It appears lighter in natural lighting at times, but usually it's an inky dark blue like the picture above.
