The company originally produced clocks as less expensive alternatives to the high-end European counterparts of the time. In 1887, they introduced the large "Jumbo" pocket watch, invented by Archibald Bannatyne and named after the famous P. T. Barnum elephant. The "Jumbo" was put on the market in New York City on a trial basis, catching the attention of Robert H. Ingersoll, a salesman and eventual marketing pioneer. During the turn of the century, Waterbury Clock Company produced millions of pocket watches for the Robert H. Ingersoll & Bro. watch company, in which Robert partnered with his brother Charles. In 1896, Ingersoll introduced the "Ingersoll Yankee", a dollar pocket watch supplied by Waterbury Clock Company. These watches gained such great popularity that they became known as ""the watch that made the dollar famous.""
