Robert H. and Charles Ingersoll founded the Ingersoll Watch Company in 1892, now one of the oldest American watch brands. Among others, James Dean and Gandhi owned an Ingersoll, and the Mickey Mouse Watch was the world's first licensed watch. Other innovations attributed to Ingersoll include Radiolite luminous numerals, the smallest pocket watch, and the first military watch. To this day, Ingersoll remains true to the ethos of its founders.
