The seller has been very honest about the ‘issues’ which is good.
If there is documentation (not likely by the wording) around the recase then ok(ish), the value reflects it and I assume everything else was from the one source and is original.
The more significant point for me is the dial damage as the dial is where most of the value is.
For both points if you ever resell then they will for sure have an impact on value. If it’s a keeper then no issue as regards that.
