US Based Watchmaker needed to fix screw-in crown DOXA Aqualung

Any recommendations for a watchmaker based in the USA (preferably West Coast) who can fix a crown on a DOXA Sub 300T Aqualung? It is the original crown that no longer screws in. Preference is to fix crown as opposed to replacement, unless a vintage crown is available.




*This watch was found on the ocean bed by a diver. The crown worked then. Took a licking but kept on ticking.

Thanks.

Repairing the crown is going to be a tall order. Vintage crowns aren't exactly plentiful either...

Good luck with the repair...you should probably replace the case tube while you are at it, if you can find the parts.
