VERY RARE AND INTERESTING PRECISION REGULATOR CLOCK "RIEFLER",
Very rare museum-quality clock which, in its time, was one of the most precise clocks in the world with an accuracy of less than one tenth of a second.
Sigmund Riefler, born on 9 August 1847, was a well-known German physicist and precision watchmaker. After his studies at the Technical University and the University of Munich, he turned to precision watchmaking in 1888 and completed his first precision pendulum clock in 1889. In addition to an almost temperature-constant Invar pendulum, he developed a gravity escapement and a spring-force escapement for pendulum clocks. He died in Munich on 21 October 1912 at the age of 65.
