Railroad and railway watches

Timetables made accurate timekeeping a matter of safety. After a fatal collision at Kipton, Ohio, in 1891, American railroads adopted strict standards: open-face watches, lever setting, at least 17 jewels, adjustment to temperature and five positions, and a performance within 30 seconds a week, inspected regularly by approved watch inspectors. Waltham, Elgin, Hamilton, Illinois and Ball made railroad-grade watches in large numbers.

European railways issued service watches to guards, drivers and station staff, often engraved with the railway's initials and a staff number. Such watches link industrial timekeeping with the standardisation of time zones (Greenwich Mean Time adopted by British railways in 1847; North American standard time in 1883).
