Precision pendulum clocks

This long-awaited volume chronicles the horological work carried out in France, Germany, and North America and completes the fascinating history of precision timekeeping in recent time. In France, renowned clockmakers include the Berthouds, the Lepautes, Robin, Janvier, Lepine, LeRoy and Leroy, Bourdier, Jacot and Jarossay. In Germany the primary emphasis is on Riefler, Strasser, and Rohde, but the works of other important makers are also considered. America's contribution to precision timekeeping is chronicled including the works of Seth Thomas, Charles Fasoldt, William Bond and Son Co., E. Howard and Co. and others. Recent advancements in timekeeping include the W5, a clock created by Philip Woodward and the Littlemore clock created by Professor Hall, almost certainly the most accurate pendulum controlled clock the world has known. Over 500 beautiful color and black-and-white photographs illustrate the historical contributions of these eminent clockmakers.
