The Self Winding Clock Company was one of the largest manufacturers of clocks in America from the late-nineteenth century to the mid-twentieth century.

Brief history

Located in New York City with a satellite branch in Chicago, Illinois, the Self Winding Clock Company is most famous for producing the series of four nine metre diameter clock faces that adorn the Metropolitan Life Insurance Company Tower in New York.

The company also commissioned products for organisations such as the Western Union and produced clocks for London Underground stations at Tooting Bec and Balham. Although the actual clock parts themselves were made by the Self Winding Clock Company, these clocks were actually fitted by companies such as H.C. Thompson, Seth Thomas and Howard.

Formed in 1886 by Henry Chester Pond and Charles Pratt, the Self Winding Clock Company based its design on automatically winding clocks each hour with motor powered dry cells located in the case. The company testified that this pendulum controlled movement, combined with the continual driving force of the frequently wound mainspring, would yield an exceptionally accurate clock subject to the least amount of wear.

The company also gave an optional accessory, which allowed their clocks to be synchronized each hour via U.S. Naval Observatory times signals that were sent over Western Union telegraph lines. In 1883, the Naval Observatory agreed to telegraph standard railway time, which dramatically aided Western Union, who at the time happened to own the Self Winding Clock Company.
