The evolution of precision timekeeping instruments

The invention of the tourbillon 200 years ago offset the influence of gravity on the movement of a watch. In 2008, the patented Lange stop-seconds mechanism made it possible to stop the tourbillon to precisely set the watch for the first time. In the movement of the new A. Lange & Söhne 1815 Tourbillon with enamel dial, it interacts with the Lange ZERO-RESET function, assuring one-second accuracy when stopping and setting the timepiece.
