A. Lange & Söhne 1815 Tourbillon
1815 Tourbillon is a luxury wristwatch by A. Lange & Söhne.
Presented in 2014, this model in the “1815” series not only features the complication of a tourbillon and the addition of a stop-second invented and patented by Lange, but also adds a zero-reset function in which the second hand jumps back to zero when the crown is pulled. This allows the watch to be accurately set and restarted to the second.
