Hamilton Railway Watch

In 1891, a railway engine driver’s pocket watch running four minutes slow caused a severe train accident in the United States. The railway company responded by setting up strict standards for its pocket watches, stipulating the case size, the number of stones, and a weekly error of less than half a minute etc. Hamilton, Waltham, and the other watchmakers that met the initial specifications started the history of railroad watches.
