Fake Lange gold watches are counterfeits that copy A. Lange & Söhne designs but use gold plating over brass or steel instead of solid 18k gold. Four checks expose most of them: the German hallmark, the caseback engravings, the hand-finished movement, and the weight of the case. A real Lange carries a 750 stamp plus the crescent moon and crown mark, and it feels dense in the hand.
What separates a fake Lange gold watch from a real one?
A genuine Lange case is solid 18k gold or platinum, hallmarked, and numbered to match its movement. A counterfeit usually hides a base metal core under a thin gold layer, so the case is light and the stamp is shallow or missing.
Lange also finishes its movements by hand in ways that mass production cannot copy at low cost. That difference shows through the sapphire caseback.
How can you tell fake Lange gold watches apart?
1. Check the gold hallmark and case material
Look for the number 750, which means 18k gold, and the German crescent moon and crown stamp. Poorly spaced digits, uneven depth, or a missing stamp point to a plated case.

White gold and platinum pieces should also carry the correct purity mark for the metal, not a generic stamp.
2. Weigh the watch and feel the case
18k gold has a density near 15.5 g/cm3, roughly double that of brass or steel. A gold Lange is heavier than a same-size stainless watch, so a featherweight case is a clear warning.
3. Inspect the movement through the caseback
Real Lange movements show a Glashütte three-quarter plate, blued screws, screwed gold chatons, and a hand-engraved balance cock with the brand signature. Fakes display flat, machine-stamped plates or printed decoration.
The outsize date on a Lange 1 jumps instantly and stays aligned. Fakes often drift, cycle slowly, or sit crooked in the window.
4. Compare the engravings and serial number
Lange engraves the reference number, case number, and metal mark with crisp edges and consistent depth. Laser-etched or acid-etched text with fuzzy borders is a counterfeit trait.
The case number should match the records for that reference, and the movement number should sit on the bridge, not on a glued plate.
5. Question the price and the seller
An 18k Lange 1 or Saxonia trades for tens of thousands of dollars, even used. A solid gold case alone is worth more than scrap value plus labor, so a few hundred dollars cannot buy a real one.
Are all A. Lange & Söhne watches made of gold?
Nearly all of them. Lange builds current production in 18k yellow, rose, and white gold, plus platinum, with only a handful of historic steel pieces. A run-of-the-mill steel Lange at a bargain price is almost certainly fake.
What do fake gold Lange watches get wrong most often?
- Gold plating that wears off at the lugs, crown, and caseback edges.
- Printed or stamped movement decoration instead of hand engraving.
- Wrong fonts or spacing on the dial logo and the caseback text.
- A crown that does not seat correctly or a caseback that fits poorly.
- Sapphire that scratches easily because it is mineral glass.
Frequently asked questions
Is a gold-plated Lange fake actually gold?
No. Plating is typically 5 to 20 microns of gold over brass, nickel, or steel. A jeweler can confirm this with an acid test, X-ray fluorescence, or a density measurement.
Can a watchmaker confirm whether my Lange is real?
Yes. A watchmaker can open the case, verify the hallmark and serial numbers, and examine the movement finish. An authorized Lange service center can also match the numbers against factory records.
Do fake Langes ever use real gold cases?
Rarely, but it happens with recased or rebuilt watches. In those cases the gold is genuine while the dial, movement, or papers are not, so buy on paperwork and provenance, not just metal content.
