Tourbillon Pour le Mérite

Tourbillon Pour le Mérite — 701.001

Unveiled at A. Lange & Söhne’s historic October 1994 rebirth collection, the Tourbillon "Pour le Mérite" (Reference 701.001) represents the absolute pinnacle of modern German watchmaking. Born from the visionary ambition of Günter Blümlein and Walter Lange to restore Glashütte’s former glory, housing the groundbreaking hand-wound Caliber L902.0—developed in collaboration with movement legends Renaud & Papi, it holds the distinction of being the first-ever wristwatch to combine a fusée-and-chain constant force mechanism with a tourbillon regulator.

Encased in a classic 38.5 mm yellow gold case (10 mm thick), the Reference 701.001 pairs a warm champagne dial with traditional pocket-watch-inspired aesthetics. Its layout features a railway minute track, running small seconds, a 36-hour power reserve indicator (AB/AUF), and a striking aperture at 6 o'clock revealing the hand-finished, 84-part tourbillon carriage beneath a mirror-polished bridge anchored by a diamond endstone. Beyond its visual restraint, the movement showcases legendary mechanical depth: its fusée-and-chain system utilizes a 15 cm chain comprising 636 parts and a 38-part planetary gear setup to deliver uniform torque across its entire power reserve.

As the definitive core reference of the line, the yellow gold 701.001 accounts for 104 of the 200 total Pour le Mérite timepieces ever produced between 1994 and 1999. Originally debuting at a retail price of 125,000 Deutsche Marks, the reference has matured into one of the world's most sought-after A. Lange & Söhne pieces, deservedly. Combining historical weight, exceptional proportions, and monumental technical significance, Reference 701.001 stands as an indispensable cornerstone of high-complication watch collecting.
