AMERICAN WATCH Cº pocket watch

In 1851, the American Watch Cº company was formed, which the following year became the Walthan Impovement Cº, before passing in 1885 to the powerful Walthan Watch Company.
The watch he wore on the day he was elected president, Abraham Lincoln in 1860 was a silver America Watch, and later he received a gold pocket watch, model "Wm Ellery," No. 67613 of 1864, where his watchmaker wrote the alleged secret message.
