Short answer
A fake Lange tourbillon is a counterfeit watch built to look like an A. Lange & Söhne tourbillon. Real Lange tourbillons are hand-finished German watches that sell for six figures in US dollars. Counterfeits sell for $150 to $900. The gap shows in the movement, the case finish and the paperwork.
Why Lange is hard to copy
A. Lange & Söhne works from Glashütte, Saxony. Walter Lange restarted the firm in 1990 after German reunification. The first collection arrived in October 1994 and included the Tourbillon "Pour le Mérite," a hand-wound tourbillon with a fusée-and-chain drive. Few workshops build either part at that level.
Finishing is the second barrier. Lange movements use a three-quarter plate in untreated German silver, screwed gold chatons, blued screws and a balance cock engraved by hand. Each engraver cuts the pattern freehand. Two cocks never match.
What the fakes get wrong
- Movement: most fakes run a stock Chinese tourbillon or an Asian clone of an ETA. Bridges show machine stripes, not frosted German silver.
- Chatons: the gold color is plating on brass. Real chatons are gold, held by two or three blued screws.
- Engraving: laser-etched, identical on every copy. The vine motif repeats at the same angle and depth.
- Tourbillon cage: on a fake, the cage sits under a flat bridge with screws at odd angles. Lange polishes the cage bridge by hand to a black finish.
- Dial printing: thick ink, soft edges. Lange prints thin and crisp.
- Outsize date: the two discs on a fake can misalign at midnight. Lange date discs cross in one jump.
- Case: sharp lugs, uneven brushing, shallow crown engraving.
- Weight: a plated fake feels light for its size. Lange gold cases are solid.
The tourbillon itself
Many cheap "tourbillons" are open-heart dials with a spinning disc. A real tourbillon puts the balance and escapement in a rotating cage, one turn per minute in most designs. Chinese factories do build real tourbillon movements, so a turning cage proves little alone. Judge the cage finish, the bridge above it and the engraving on the cock.
Box, papers and price
A real Lange arrives with a guarantee booklet, a numbered certificate and a wooden box. The case number and movement number match. Sellers of fakes supply photocopied booklets and generic boxes. A price below market for a tourbillon is the first signal. Lange tourbillons do not sell for four figures in any condition.
Legal status in the US
Counterfeit watches violate US trademark law. 18 U.S.C. § 2320 covers trafficking in counterfeit goods. Customs can seize and destroy shipments under 19 U.S.C. § 1526. A buyer who imports one risks losing the watch and the money.
What to check before you buy
- Ask for a photo of the caseback under direct light. Compare the engraving to a photo from Lange.
- Check the case and movement numbers against Lange's archive. Lange confirms a watch when it comes in for service.
- Ask for the weight in grams and compare it to the published figure for the reference.
- Read the paperwork: booklet print quality, number matches, service history.
