here are a few books recommended for watch collectors: General references The Ehrhardt Price Indicators--great for the pictures. A MUST Other Ehrhardt spiral bound books on other watches--American and Foreign. Great for pictures and my "staring and comparing." The Col. Townsend books, inc. "Almost everything you wabnted to know about American Watches and Didn't know who to ask"; "The Watch That Made the Dollar Famous"; and "American Railroad Watches." For Howard info--try the Col's book on Howard watches. ALL MUSTS. "The Beginning to End Book" by Roy Ehrhardt--A MUST. Harrold, Mike. "American Watchmaking, suppliment #14" and available from the NAWCC library for about $6. (one of the MB chapters actually asks $15. or more for this book which is an obscene profit). You do not have to be a member to acquire this book from the nawcc bookstore. Good history but many errors. "It's About Time" by Maj. Paul Chamberlain--SCARCE AND OUT OF PRINT. A MUST. Topical books: Illinois Watches by Meggers and Ehrhardt--A MUST along with the Chapter 149 CD on the subject by Dr, Russ Snyder. Marion, by Muir and Kraus--available from the NAWCC book store on line for abt $16.00. A MUST for US Watch Co. collectors as well as the Hanson-Ehrhardt book on Marion Watches. "Timing a Century" by Charles Moore--a history of the Waltham Watch Co.--SCARCE AND OUT OF PRINT. "History of Watch and Clockmaking in America" by Charles S. Crossman, republished by Don Dawes--limited 200 printing, now out of print--A MUST. "America Watch Factories" by Abbott. A MUST. "The Marine Chronometer" by Commander R.T. Gould--A MUST. Out of print but reprined. "The Ships Chronometer" by Marvin Whitney This ought to get you started, as I have many more books you, the collector, should own and I HIGHLY RECOMMEND buying important (or even collecting) horological books. A few readers scoffed at my book recommendations (even suggested that I do all this for personal gain-what a joke), but what I tell you is THE TRUTH and THE WISE THING TO DO.
