I was able to locate the following:
Past Time Pocket Watch Parts in NC - http://ptpwp.com/
Antique Pocket Watch - http://www.antique-pocket-watch.com/sitemap.html
http://www.watchparts.org/ - watch repair.
Do you have a specific brand/model of watch needing attention, and I can research further for you?. The above seemed to focus on most brands.
Please let me know if I can help further.
