This endangered species strap is shown for display purposes only and is not for sale. The watch will be supplied with a calf leather strap.
The present Datograph Perpetual Tourbillon is no. 37 of the limited edition of 100 examples of the model in platinum. Consigned by the original owner it is preserved in excellent overall condition and sold with the full set of accessories.
The Datograph Perpetual Tourbillon is doubtlessly one of the most technically and functionally brilliant timepieces ever conceived. Released at the in SIHH 2015 to the great awe of the audience, it was created by A. Lange & Söhne to showcase their prowess and leading position in the field of watchmaking. So complicated and exclusive is this watch that only 100 were made (the present example being numbered 037). Essentially speaking, it manages to combine a jumping displays perpetual calendar, flyback chronograph, tourbillon, moon phases and finally a power reserve indicator (near the end of the tachymeter scale), all driven by a stunningly finished movement visible through the sapphire case back.
As beautiful as the watch’s dial side is, it is the movement that is truly impressive and characteristic of Lange’s technical perfectionism and attention to detail. Not only simply aesthetically astounding (with a hand-engraved balance cock and an incredible level of hand-finishing) it is also designed with function in mind. Two subtle yet complicated mechanisms underline just how intricate calibre L952.2. is. Firstly, pulling the crown out to adjust the time instantly stops the movement, halting the tourbillon, allowing the time to be displayed with an accuracy of one-fifth of a second. This function, first introduced in 2008 by Lange, has been made possible by the modification of the balance, which now oscillates at a slightly lower frequency.
Secondly, and perhaps most impressively, is the watch’s unique ability to advance every single display on the perpetual calendar once (moon phases, date, day) by one single activation of the pusher at 10 o’clock. To prevent accidentally pressing it and needlessly activating the instantaneous display adjustment, Lange has designed the watch in such a way that the function is locked unless the crown is pulled out. This not only protects the movement itself but also ensures that the function is only used when the watch truly needs correction – i.e. when the power reserve has depleted (an idiosyncratic yet ultimately incredibly thoughtful and important feature).
As befitting a watch of such a high pedigree, only precious metals have been used: the hands are rhodium-plated and solid gold and the case is made of platinum.
The present example is a must-have for the avid collector, and for those desiring to experience how far the innovative and technical boundaries of horology can be pushed.
