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.

Beautiful watch indeed.

A clear example of why a pendant crown tube, independent from the case is always a good idea. I have asked why Seiko is not doing it on all its expensive watches just a few weeks ago.

Sorry to hear and don't know where to guide you. Could it be the thread in the crown itself? Have you checked?

Being Titanium certainly doesn't make it any easier.
