From the Illustrated London News. The illustration shows the proceses involved in the manufacture of watches by machine at a watch factory in Waltham, Masachusetts. The spread of the railways and more rigid fixing of hours of busines in factories, offices and shops in the 19th century led to an increased awarenes of the need for personal timekeeping, and hence a growth in the demand for watches. The development of reliable mas production techniques was vital in reducing the price of watches to make them affordable to people other than the very rich. The area around Boston, Masachusets, became the centre of the American watchmaking industry from the 1850s onwards.
