Richard Lange Jumping Seconds - A Lange & Sohne

A BIG STAGE FOR SECONDS

The jumping seconds mechanism ranks among the classic complications in precision horology. Among other applications, pocket watches equipped with this device in the past were used to determine sidereal or solar time. Ferdinand Adolph Lange developed such a mechanism very early on, in 1867. Ten years later, the newly founded Imperial Patent Office granted him one of its first patents for his invention.
