Datograph Perpetual Tourbillon

A. Lange & Söhne 2016

ref. 740.036F
Men's

How to combine three complications plus five additional functions in a 41.50-mm diameter, without sacrificing legibility? A. Lange & Söhne has found the answer with this platinum watch, driven by the in-house, manual-winding L952.2 calibre. The black solid silver dial presents the indications for the column-wheel chronograph with a precisely jumping minute counter, complete with fly-back function and outsize date. The instantaneously jumping Perpetual Calendar indications elegantly frame the moonphase display. The intricate Tourbillon mechanism is revealed through the sapphire crystal back. A tour de force that A. Lange & Söhne is limiting to just 100 pieces.
