Great low tech design

Christopher Fahey: "An elegant solution, designed and patented in 1901 by the German engineer A.A. Newman, is called the 'watchclock'. It's an ingenious mechanical device, slung over the shoulder like a canteen and powered by a simple wind-up spring mechanism. It precisely tracks and records a night watchman's position in both space and time for the duration of every evening. It also generates a detailed, permanent, and verifiable record of each night's patrol."
