Hairspringing begins: There is not one watchmaker in a hundred who can fit a hairspring properly, and not one in fifty who knows a correct one when he sees it. The above sentiment expressed by a recognized authority -- though, no doubt, too sweeping, still indicates such a lack of information as to furnish plenty of excuse for an essay on the hairspring -- the soul of the watch, which has been the subject of the study of the philosopher and experiment of the mechanic, as well as the theme of the essayist, ever since the days of Dr. Hooke.
Originally published in 1908, Hairspring: The Manipulation of Old and New Springs by the Watch Repairer is the 1993 reprint of this important essay.
