The short answer
A fake Lange 1 380.022 is a counterfeit of A. Lange & Söhne's Lange 1, the hand-wound dress watch with an outsize date at 1 o'clock, an off-center time dial, and a small seconds subdial near 4. No replica on the market reproduces the real thing's movement, and most fail at the dial before you even flip the watch over. If a listing calls itself "1:1 Swiss made" and prices a gold-cased Lange 1 at a few hundred dollars, that listing is describing a watch that does not exist.
What the genuine reference is
The Lange 1 is a 38.5 mm hand-wound watch built around the L901.0 calibre: 53 jewels, roughly 72 hours of power reserve, a three-quarter plate in untreated German silver, gold chatons, blued screws, and a balance cock that a person engraved by hand. The 380.022 falls inside that family. Lange has used many case numbers across the Lange 1 line, and sellers often pair the same number with different dial colors and case metals, so treat any single photo as one example rather than a spec sheet. Verify the exact configuration against A. Lange & Söhne's own records before you trust a number.
Where replicas give themselves away
The movement
This is where the gap is widest, and it is where I look first. A real L901.0 has a hand-engraved balance cock, so the floral pattern differs on every single watch. Replicas use stamped or laser-etched decoration, which means the pattern repeats. Compare two fakes from the same batch and the engraving matches line for line. Check the gold chatons too: on the real movement they are actual gold settings around the jewel, not plated rings. The blued screws on a genuine watch are heat-blued steel; on a replica they are usually painted or chemically colored and look flat under a loupe.
Dial and outsize date
The outsize date is two separate discs that jump instantly. Replicas frequently run a single disc, or two discs that drift and leave the numerals sitting at different heights. Look at the printing: genuine dial text is crisp and thin, with "Made in Germany" under the brand name. Applied markers on the real watch are solid gold. Fakes use plated brass, and the edges catch light differently. Subdial hands on replicas are often the wrong length or the wrong shape.
Case, crystal, and feel
A Lange 1 sits low, around 10 mm thick. Replicas tend to run 11 to 12 mm, so the watch rides high on the wrist and the crown feels wrong between your fingers. If the case is described as white gold or platinum, it should feel dense for its size. Rhodium-plated steel does not. Caseback screws, the polished edge of the sapphire crystal, and the strap hardware are all worth a look. Most fakes cut corners there because nobody photographs the back of the buckle.
The price reality check
A precious-metal Lange 1 trades in the tens of thousands of dollars on the secondary market. That number is the whole reason a replica exists. It is also the reason a "mint, full set" 380.022 at $800 is not a bargain. Nobody sells a real one for less than the metal inside it is worth.
Practical notes before you buy
- Ask for sharp, straight-on macro photos of the movement, the date window, and the caseback screws.
- Ask for a video of the date change. Watch whether it snaps or crawls.
- Weigh the watch. Precious metal and steel do not feel alike in the hand.
- Budget for servicing. The Asian hand-wind movements inside replicas are not built for Lange service intervals.
One more thing worth saying plainly: importing counterfeit goods into the United States is illegal, and selling a replica as genuine is fraud. If you buy a replica, buy it knowing exactly what it is, and never let it leave your hands described as anything else.
