1815 TOURBILLON
Progress in precision
For over 200 years, the tourbillon has been the paragon of horological precision. Presented by Lange in 2008, the patented stop-seconds mechanism made it possible for the first time to stop the tourbillon at will and accurately set the watch. Now, the 1815 TOURBILLON takes this development a step further: thanks to the ZERO-RESET function, the seconds hand jumps to the zero position when the crown is pulled. This allows the watch to be precisely set and restarted with one-second accuracy.
