Can anyone with a lupe tell me if he has the same engraving?

Hello Guys,
Im new to the forums, since i bought my first rolex explorer from the grey market (Trusted seller) a week ago...Its supposed to have been bought in the year 2019..
I happened to have a lupe laying around, and i took a look at the clasp engravings, where i noticed that there are two points under the O, and X of rolex (S. picture, although its very hard to see)..
Does it mean, that the clasp is not original, or is this just normal?..Can anyone with somehow new rolex take a look at his clasp with a lupe, and tell me?
