The short answer
There is no Falkenhausen model in A. Lange & Söhne's archive. No reference number, no limited edition, no factory nickname. The word turns up in forum posts and in replica listings, almost always attached to the Lange 1, and it traces back to a garbled or invented label rather than a watch that ever left Glashütte. What people are usually reaching for is the real story: the 1994 Lange 1, the first watch of the brand's second life. That history matters because it tells you exactly which details a fake has to get right.

Where the actual Lange 1 history starts
Ferdinand Adolph Lange set up shop in Glashütte in 1845 and turned a poor Saxon village into a watchmaking town. The company was expropriated in 1948 and folded into a state combine. Walter Lange, the great-grandson, left for the West and waited four decades.

He came back in 1990 and refounded the firm with Günter Blümlein. On October 24, 1994, they presented four watches in Dresden: the Arkade, the Saxonia, the Tourbillon Pour le Mérite, and the Lange 1. That date is the one to remember. Everything the replica market sells as a Lange 1 is chasing those four models.
The design details that define the original
The Lange 1 broke the rules on purpose. The dial is asymmetric. A large date sits at the top right, a small seconds subdial at the bottom left, a power reserve arc at the top left. Nothing lines up, and that is the point.
- Outsize date, inspired by the Five-Minute Clock in Dresden's Semper Opera House. Two separate discs, one for each digit.
- Untreated German silver three-quarter plate, so the movement ages to a warm tone instead of staying bright.
- Hand-engraved balance cock, done freehand by one engraver, never stamped.
- Screwed gold chatons and heat-blued screws.
- Manual winding, 21,600 vph, roughly 38.5mm across in the first generation.
Why "Falkenhausen" keeps showing up
I have looked at a lot of listings with that name in the title, and the pattern is consistent. Sellers borrow a German-sounding surname to make a listing look archival. Sometimes it is a mangled transliteration of a dealer name, sometimes a forum handle that got copied forward until people assumed it was a reference. Other times it is attached to a made-up "limited edition" to justify a higher price.
Test it yourself. Ask any seller who uses the name for the reference number and the year. A real Lange reference looks like 101.027 or 191.032. There is no Falkenhausen entry in the Lange catalogue, and no auction record under that name.
What to check on a fake Lange 1
Knowing the real watch makes the flaws obvious. The date font is the first tell. Lange uses a tall, narrow numeral with tight spacing, and cheap copies widen it. Next is subdial placement: the small seconds should sit low and left, not centered. Flip the watch over. A stamped or laser-etched balance cock is an immediate giveaway, since the original is cut by hand and the pattern never repeats. Check the power reserve hand for correct travel and the caseback engraving for crisp depth. Case thickness is another one. Copies tend to run thick.
Bottom line
The Falkenhausen name is noise. The watch worth studying is the 1994 Lange 1, and its history is short, specific, and well documented. Learn the dial layout, the date font, and the movement finishing, and the label on a listing stops mattering.
