Waltham fans, this is a GREAT book for you!
Back in print, a historical 1940 edition of the Waltham Watch and Clock Material Catalog.
The catalog has been digitally process and cleaned up so that... More > it is easier to read.
82 pages in total, all crammed full of illustrations, part lists, factory part numbers, etc. Some movements can only be found in this catalog, not the later versions.
Many sizes and models/grades are represented... 8-day Chronometers, 18 size, 16 size, Colonials, all the way down to the 4 ligne 400 model.
Also has much information on dials, dial numbers, Waltham Premier named watches and their appropriate dials.
The content is fascinating and there's plenty to absorb and reference. Certainly a great addition to any horological library.< Less
