Ball defined strict manufacturing guidelines for precision railroad timepieces, including magnetism resistance and multi-position adjustment, which became general standards.
His guidelines required resistance to magnetism, reliable timekeeping in five positions, isochronism, and power reserve. These standards were adopted by major manufacturers like Waltham and Elgin, ensuring only approved watches were used on railroads.
