Lot Essay

Launched in 2012 to great acclaim, this superb, highly complicated and incredibly attractive platinum Lange 1 Perpetual Tourbillon was made in a limited edition of 100 pieces worldwide. The present watch, with the reassuring single owner provenance of the Champion Collection is offered with the full set of accessories and has been carefully preserved in immaculate condition.
The original Lange 1 was one of the first four timepieces released in 1994 by A. Lange & Söhne, and the model that features all the traits which are now so closely associated with the brand. Combining technical excellence, size and aesthetics, the 41.9 mm. diameter Lange 1 Perpetual Tourbillon as its name suggests, features two of the most famous and useful complications to be found in horology, the perpetual calendar and the tourbillon.
Powered by the Lange caliber L082.1 automatic movement, it has an extraordinary level of finishing and in common with the best and most sophisticated wristwatch tourbillons, the tourbillon mechanism itself is visible only through the sapphire crystal caseback. The stunning dial is devoted to the time and calendar functions including of course Lange’s famous large date apertures at 10 o’clock. The months are displayed by a rotating outer ring, indicating the current month at 6 o’clock immediately below the leap-year aperture at 6 o’clock. The day of the week is indicated with a retrograde hand at 9 o’clock, and the moon phase with seconds at 8 o’clock.


The perpetual calendar is one of the most useful watchmaking inventions of all time, credited to the Englishman Thomas Mudge who made a perpetual calendar watch in 1762, the mechanism not only self-adjusts for the number of days in the month but also calculates the correct adjustment for the leap-years. The tourbillon, invented and patented by the genius Abraham-Louis Breguet in 1801, is one of the most enduring technical improvements to timekeeping precision and has been continually improved to extreme degrees. In a tourbillon, the entire escapement revolves so that any adverse effects on timekeeping caused by the watch’s position – up, down, sideways etc, is equalized. The tourbillon is also a very visually appealing complication and it has become an important feature of many of the great modern complicated wristwatches.
Very rarely seen at auction, this Lange 1 Perpetual Tourbillon showcases Lange & Söhne’s watchmaking at its very best and offers collectors the chance to obtain an undoubted masterpiece of the brand in exceptional condition.
