Markings/dots on Crown - 16613, 1997.

[LucasK]

Hi,

First of all, nice to be here!

Yesterday I finally recieved a grail of mine, a Submariner 16613 from 1997.
Im beyond happy finally obtaining one, I just have one small concern - the crown.
The markings or dots (that defines what type of screw-down the watch has) on the crown seems to have faded and are hardly visible from some angles.

How should a 24 year old Crown in gold look? Do the dots "fade"? Or is it likely that the watch has been polished to hard?

Attached 3 images, from different angles.
Would appreciate someone more experienced giving their opinion!

Best regards
