Elgin Chronograph Prototype

As master model maker at the Elgin National Watch Company, Charles P. Corliss worked on a variety of prototypes and experimental pieces. A patent issued to Corliss in April 1886 indicates there was substantial development to explore the possibility of introducing an Elgin chronograph to the market. One such chronograph prototype, very likely a creation of Corliss, survived and was held at The Elgin Museum until sold by Heritage Auctions in May 2018.

This remarkable prototype features hints of Corliss’ 1886 patent. The movement serial number falls within the 375,000 range, an established block generally reserved for factory prototypes and special production.
