As president, Abe passed on fine watches received as gifts and used his own pre1962 civil war silver cased key wind 11J William Ellery. A 1923 ad shows one like it but with Waltham name drawn on the dial. Shown here is the authentic actual silver twin to the real one at about same age without any Waltham marking anywhere. On better grades, American Watch Co., Waltham, Mass. marking was used. Boston Watch Co. and William Ellery model became part of AWWco. It was not the lowest grade for the future
Waltham. There were 7J models. Anyway it is still a good performer thus supporting the old 1923 ad claim for grandfathers using them. There were many hundreds made and are still available cheap. Some history has it as a hunting case model, but most and the ad show it correctly as open face.
Modified good movement photo did not load. I sometimes cannot load a digitally corrected image. Why? Second click on image for details. Added 1919 Maximus shown in ad.
