Seiko Ashtray 7c46-6010 stripped crown lock

2104 Views 16 Replies 11 Participants Last post by  MediumRB

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.

To me the crown of the 300m 7C46 Tuna looks somewhat like the one on the Ashtray other then the obvious that one is titanium and the other is steel. I wonder if one from a SBBN007 would work?

Anyway, good luck on the repair, those Ashtrays look great and a very unique watch
So it all depends what you now want to do. Look for the correct crown that is Ti or settle for a SBBN007 crown.
