How to Spot a Fake A. Lange & Söhne Watch
A. Lange & Söhne makes about 5,000 to 6,000 watches a year. The company sits in Glashütte, Saxony. Cases are gold or platinum. No Lange runs on a battery. If a watch ticks one step per second, it holds a quartz movement, and Lange has never sold one.
Price and Case
An entry Saxonia starts near $18,000. A Lange 1 runs past $40,000. Copies sell for $150 to $800. A solid gold Lange 1 weighs about 100 grams. A fake in brass or plated steel often weighs less than 70 grams.
Check the hallmarks. Gold cases carry stamps such as 750, or the German crown and sun mark. Fakes skip them or stamp them on the outside of the caseback.
The Movement
Lange builds its own calibers. The Lange 1 uses the L121.1, a hand-wound movement with 72 hours of power reserve.
Three features show up on every Lange movement:
- The three-quarter plate, a large plate that covers most of the movement, with Glashütte ribbing.
- Screwed gold chatons. The screws are blued by hand.
- A hand-engraved balance cock. Each one carries a floral pattern. No two match.
Fakes use stock ETA, Sellita, or Seagull movements. Look for a small plate, no ribbing, chrome screws, and a stamped or laser-etched balance cock.
The Outsize Date
The Lange 1 date sits at the top right. Two separate discs make the number. The date jumps at midnight in one step.
On fakes, the two digits often sit on one disc. The font is too wide or too bold. The window frame has a different shape.
Dial and Hands
The Lange 1 layout does not move: outsize date top right, time at 9, small seconds at 5, power reserve at 3. Off-center subdials point to a fake.
Hands are gold, faceted, and curved along the length. Fake hands sit flat and carry paint.
Caseback and Serial Numbers
Most Lange models have a sapphire caseback. The crystal sits flush with the case. A thick, domed caseback with a sticker points to a fake.
Each watch has a serial number. Lange holds records. A boutique can check a number against the archive. Numbers that repeat across listings, or numbers stamped on a separate plate, are a sign of a fake.
Buying Checks
- Weigh the watch. Compare it to the published figure.
- Watch the second hand. One jump per second means quartz.
- Look at the balance cock through the caseback.
- Check the date change at midnight.
- Ask for the papers and the serial number.
- Compare the asking price to auction results.
No single check settles the question. Two or three failing at once does.
