u/Acceptable-Cut8038

I am considering this 14800ST for a milestone purchase. This would be my first AP. The alignment of the bolts concern me, but I like the overall look of the watch. The seller is asking around 15K. No box/papers. Advertised on a site that certifies the authenticity. Thoughts?

1. Is this a fair price?
2. What are the estimated servicing costs
3. Should I be concerned with the bolts?

Appreciate the knowledge and information from this sub!
