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.

The dial is crafted from solid pink gold and graced with solid gold applied hour markers. The hands are made of rhodium plated gold and blued steel. The hour and minute hands as well as the hour markers at 3, 6, 9, and 12 o'clock are luminous. The moon phase disc made of solid white gold features an exact representation of the celestial chart with the stars as seen from Glashütte in Germany.

The Datograph model is not only one of the most iconic models of A. Lange & Söhne, but one that designates a column-wheel chronograph with a precisely jumping minute counter, a flyback function and the typical Lange over sized date. This time, by adding one of the most noble of all horological complications —the perpetual calendar— to it, Lange takes this piece to the next level. But this is not your run-of-the-mill perpetual calendar, this is an instantaneously jumping perpetual calendar with a moon phase display. All indications of the perpetual calendar including the oversized date as well as the day-of-week —with buit-in day/night indicator—, month and leap-year displays in subsidiary dials switch instantaneously at midnight, with a snap that takes a fraction of a second.

The fascinating tourbillon mechanism is exposed on the back via the sapphire-crystal case back The beating heart inside the new SIHH 2016 A. Lange & Söhne Datograph Perpetual Tourbillon is the in-house manual wound calibre Lange L952.2 which is a work of art and one of the most amazing calibres in terms of complexity, architecture, beauty, decoration and a real treat for the eyes. This movement is composed of 729 parts and 59 jewels, one being a diamond endstone. The movement provides a power reserve of 50 hours when fully wound and for the first time in a Lange tourbillon with chronograph, the balance beats at a rate of 18,000 vph instead of the conventional 21,600 vph. Consequently, stopped times can be displayed with an accuracy of one-fifth of a second.
