Originally launched in 2016, the A. Lange & Söhne Datograph Perpetual Tourbillon is one of the most complicated watches from our friends from Saxony and this year at the SIHH 2019 it simply just got much better. A first for the brand and in a limited edition of only 100 pieces, the Datograph Perpetual Tourbillon jhas been graced this year with a very special solid pink gold dial in a white gold case. Unexpectedly, given its compact dimensions, this unique multi-complication watch features a flyback chronograph, a perpetual calendar with moon phases, a tourbillon with stop seconds, and a power-reserve indicator.
