Seiko Ashtray 7c46-6010 stripped crown lock

I recently acquired a Seiko 7c46-6010 “Ashtray” in overall nice condition EXCEPT that the crown lock is stripped.

-Watch is titanium
-Watch was only made for a short time in the 1980s and is extremely rare. New cases are unobtainable
-Seiko Japan serviced it last year but could not repair the crown lock.
-I know that “a competent watchmaker should be able to drill it out” except that all the ones I’ve asked have declined.
-I realize that “you never had a problem with a screw down crown” but the previous owner of this watch did, and it’s my problem now. It also seems to be a fairly common issue with this watch.

I am looking for someone who has experience fixing this sort of problem and is willing to take it on.

Do you know for sure the crown tube’s threads are stripped or is the crown’s threads stripped?

Have you tested the screw-down with another crown to validate? Worth a shot.
I did a crown switch with my SBBN007 and it is indeed the crown and not the stem tube that is stripped. Stem tube appears to be SS.
Well that's great news - glad you gave it a shot!
