Consultado el 1 de mayo de 2017. «As William J. H. Andrewes (2006) notes: 'In 1675 Huygens devised his next major improvement, the spiral balance spring. (...) The spiral balance spring revolutionized the accuracy of watches, enabling them to keep time to within a minute a day. This advance sparked an almost immediate rise in the market for watches, which were now no longer typically worn on a chain around the neck but were carried in a pocket, a wholly new fashion in clothing.'».
