Hamilton was slow to start it's education program. In 1958, W.O. Smith, a brilliant young watchmaking instructor at the Western Pennsylvania Horological Institute, set out to write a repair manual for the Hamilton Electric. He had written other repair manuals, and purchased a Van Horn, and later spent time at the Hamilton Factory studying the watch. With Hamilton's permission, he wrote this manual in early 1958. Hamilton agreed that it could not be improved upon, so purchased the rights from Smith, and published the official Hamilton repair manual, with slight modifications in 1959.
Overall, a great hard cover book, and a great addition to a Hamilton Electric collection.
