Hi Joseph-John,

I've had the same AK model last year but haven't had any trouble with the crown. As a matter of fact you always have to push the crown a bit to get it screwed on and it also needs to get into the right position to screw correctly, but that's just as it is with any other Rolex model, you that anyway.
But your description seems a bit too much for what I would call perfect though it's very difficult to judge it without having the watch in one's hand.
However, in doubt it's always best to get the watch checked by Rolex.... You never know...
