The Riefler escapement is a mechanical escapement for precision pendulum clocks invented and patented [1] by German instrument maker Sigmund Riefler in 1889. [2] It was used in the astronomical regulator clocks made by his German firm Clemens Riefler from 1890 to 1965, [ 3 ] which were perhaps the most accurate all-mechanical pendulum clocks made.
Sigmund Riefler was born on 9 August 1847 to Magdalena and Clemens Riefler. He studied mathematics, geodesy and mechanical engineering at the Technical University of Munich, and then physics and astronomy at the University of Munich. From 1870 he worked as an engineer in the Royal Prussian Land Survey, surveying land in Schleswig. [3]

The book became a perennial best-seller, read by many students as they prepare for their first year in law school. According to a 2007 story in The Wall Street Journal, One L continued to sell 30,000 copies per year, [5] many to first-year law students and law school applicants. It challenged the Socratic method and made people think critically ...
In contrast to open formats, closed formats are considered trade secrets. Open formats are also called free file formats if they are not encumbered by any copyrights, patents, trademarks or other restrictions (for example, if they are in the public domain) so that anyone may use them at no monetary cost for any desired purpose.

The escapement was never mass produced, and no examples are known to exist. It might be relevent to the Sigmund Reifler biographical article but not here, as the watch escapement was necessarily different from his pendulum clock escapement. There is a more important problem with this article. Riefler invented two pendulum clock escapements.
