Having doubts [SNE585p1]

Finally pulled the trigger on this beautiful solar diver.

However, when I looked underneath the caseback, it had some of the printing rubbed off? The shop was legitimate, from Japan, but I'm still having doubts.

Lume is fine, bracelet is good.

Please pardon the post. I know some people gag at the sight of legit checks.

Any help is appreciated. Thank y'all!
