Rolex coke insert Real or fake

[purplesub]

Real or fake. The 8 almost touches the red but it does not. My question is this. Did Rolex make inserts where the 8 nearly touches the red but does not actually contact the red even if it is only a 1 mm away from the red. I figured the colors would be divided evenly but I have come across numerous inserts where the 1 and 8 on the 18 are not centered over the dividing color line. Are these aftermarket with th offset 1 and 8.
The material is very strong on the insert I have , no flex. 2 and 4 look ok but that red blue and red black boarder thing between the 1 and 8 has me concerned.
Thanks for any help I can get with the insert. I took the best pic of the 18 with my phone but its fuzzy. The 8 does not touch the color.
