The story
Ingersoll Watch Company grew out of a mail order business (R H Ingersoll & Bro) started in New York City in 1882 by 21-year-old Robert Hawley Ingersoll and his brother Charles Henry Ingersoll. The company initially sold low-cost items such as rubber stamps.
The first Ingersoll watches, called "Universal" were introduced in 1892, supplied by the Waterbury Clock Company. They were in reality small spring-driven clocks, about three inches diameter and over one inch thick. These were put into watchcases with pendants that carried bows and crowns like contemporary watches. The crown was not functional, the watch was wound by a captive key that hinged out, and a central wheel was used to set the hands, both accessible when the back was opened just as in a clock. At first they were sold wholesale to dealers, but later in 1892 a mail order catalogue was produced and watches were sold directly to the public.
The Waterbury watch company also initially sold the watches, but the Ingersolls soon negotiated a sole agency deal. In 1893 a smaller version of the Universal watch called the "Columbus" was made.
