Warren & Spadone were the successor to Dawson, Warren & Hyde around 1860.

The case factory utilized by Dorrance T. Warren & Amadee Spadone for manufacturing was located in Jersey City at the corner of Railroad Avenue and Barrow Street. In addition to cases, the company manufactured fine jewelry, gold pends, pencil cases, and gold chains.

The early company was a partnership under the name Warren & Spadone. Around 1870, Charles D. Rood and B.P. Smith were accepted into the firm, and the company began operating as Warren, Spadone & Co. For this reason, cases can be identified as marked "W&S" or "WS&Co." The firm of "Warren, Spadone & Hayes" (Charles D. Hayes) was listed as a wholesale sales agency in San Francisco in publications around 1869, so it is possible some cases were marked "WS&H."

By the time an feature article was published in the February 1870 issue of The Watchmaker and Jeweler about the factory, the company name had been changed to Warren, Spadone & Co.

The company was an advertised agent for the early products from the National Watch Company in Elgin, Illinois. They were also a sales agent for E. Howard and several Swiss manufacturers that exported movement to the United States.

In July 1871, the company advertised "A Watch Case Factory, Embracing All the Tools, Lathes, &c." for sale in the classified section of the New York Daily Herald.

By 1874, the company had dissolved and was succeeded by the firm of Spadon, Rood & Co.
