The Elgin National Watch Company initially produced the pocket watch in Elgin, Illinois, in 1925 — the same year Al Capone became the head of "Big Jim" Colosimo's gang. Capone became involved in Colosimo's gang in 1920 through Colosimo's nephew (via marriage) Johnny Torrio. Later in 1920, an unknown assassin shot and killed "Big Jim" Colosimo, leaving Johnny Torrio with control of the gang. In 1925, a group attacked Torrio and his wife, and he suffered several gunshot wounds. After the attack, Torrio immediately resigned from the gang and left total control to Capone. When Torrio retired, the Chicago gang grossed around $70 million (over $1 billion in 2022) annually from bootlegging, gambling, and prostitution.
