What kind of Seiko reference books are you looking for? I use a factory Seiko parts reference book for a lot of the older calibers, useful when servicing and looking up part numbers. Some of the more recent calibers are on the Seiko official web site.

Michael, I have found the Seiko & Citizen Watch Forum useful at thewatchsite.com. Under Japanese Watch Reviews... there is a FORUM ARCHIVE... Technical Manual downloads. Hope this helps.
