Which watch manufacturers can I search?

Currently, the Pocket Watch Database provides serial number lookups for watches manufactured by Elgin, Illinois, South Bend, Rockford, Waltham, Ball, Hampden, Hamilton, and Seth Thomas. Certain private label watches, such as the Burlington Watch Company (manufactured by Illinois), are also available. Date and registry serial lookups are available for the vast majority of remaining manufacturers, including Columbus, Peoria, and E. Howard. However, the data provided is not as detailed. The goal is to continue adding more information as time and resources allow.
