What is the best books i can buy for information on the Hamilton and Illinois wristwatches,,

I have bought a few wristwatches a few of which i am in the process of restoring ,I would like to learn more about production figures and what would be the correct dials ,cases etc..

Samie,
I bought a copy of the illinois watch book from Fred Friedberg at the Orlando show. I think that it is the best book available on illinois wrists. It is packed with information on dials, cases, and movements and has great pictures of most of the illinois watches.

Fred Friedberg's Illinois book is fantastic... you can get a copy at:

Well, I didn't mean to ignore Rene Rondeau's excellent book on Hamilton wristwatches, I just briefly overlooked it in my zeal for lauding Fred's Illinois book:
