The 1815 Chronograph had just started to gain a cult following when Lange replaced it with a new model. While the new piece introduced a reworked movement with longer power reserve, it did away with the pulsation scale and lost some of the charm of the original.

In 2016 Lange rectified this with the best of both worlds — a boutique only 1815 Chronograph with the upgraded movement, the return of the pulsation scale, and beautiful blue print. One could easily argue that this is the best Lange Chronograph yet.
