Quick Answer

A "fake Lange 2 perpetual" is a replica perpetual calendar watch sold under a model name that A. Lange & Söhne has never used. The Glashütte manufacturer builds the Lange 1, the Lange 1 Perpetual Calendar, the Lange 1 Tourbillon Perpetual Calendar, and the Datograph Perpetual. There is no Lange 2. When a listing uses that phrase, the seller almost always means a replica of the Lange 1 Perpetual Calendar in its 41.9 mm pink gold or white gold case, or a replica of the older Lange 1 Moon Phase that has been mislabeled.

What arrives is a replica case and dial paired with a modified third-party movement. It is not the hand-finished, twice-assembled manufacture caliber of the original, and it will not hold value the way a genuine piece does.

Prerequisites

  • Know your local law. Importing counterfeit goods is illegal in the United States and most of the European Union.
  • Set a realistic budget. A genuine Lange 1 Perpetual Calendar runs into six figures. A replica runs into the hundreds.
  • Decide what you want from the watch. If you need a working calendar complication, a replica may not deliver one.
  • Ask for the exact reference the seller is copying before you compare photos.

How to Evaluate a Replica Lange Perpetual Calendar

  1. Ask the seller to name the source model. If the reply is vague or repeats "Lange 2," treat the listing as unverified.
  2. Request photos of the caseback and the movement, not just the dial. The movement finish tells you more than the dial print.
  3. Ask whether the perpetual calendar module is functional or decorative. Many replicas show a day, date, and month that must be advanced by hand.
  4. Test the moon phase. On a real perpetual calendar it tracks the lunar cycle. On a replica it is usually a printed disc that rotates once a day.
  5. Confirm the calendar change window. A genuine perpetual calendar will not let you set the date near midnight without risking damage. Ask how the replica handles it.
  6. Measure the case. Check the listed diameter and thickness against the original reference. Replicas often run 0.5 to 1.5 mm thicker to fit the substitute movement.
  7. Inspect the dial printing under magnification. Look for fuzzy text, uneven lume plots, and subdials that sit off center.
  8. Ask about the strap and clasp separately. Most replica listings show an aftermarket strap with a clasp that does not match the original engraving.
  9. Confirm the return window in writing before you pay.

What the Replica Gets Right

A mid-tier replica of a Lange perpetual calendar can capture the overall silhouette. The off-center main dial, the outsize date aperture, and the Roman numeral layout are all reproducible with modern printing and CNC case work. Seen across a table, the proportions read correctly.

What It Gets Wrong

The finishing does not survive close inspection. Lange applies a hand-engraved balance cock, black polished steel parts, and Glashütte ribbing on the three-quarter plate. Replicas use machine striping and laser engraving. The outsize date on a replica also tends to use two mismatched discs, so the numerals sit at slightly different heights. A true perpetual calendar also handles leap years automatically. Few replicas do.

Red Flags in Listings

  • The title claims "Lange 2" or another model name the brand does not make.
  • Photos are stock images or borrowed from a genuine auction listing.
  • The price is unusually high for a replica, which suggests the seller is trying to pass it off as real.
  • The seller refuses to show the movement or the caseback.
  • Payment is requested by wire or gift card with no buyer protection.

Legal and Practical Notes

Buying a replica is not the same as buying a genuine watch, and reselling one as genuine is fraud. Keep the receipt and the seller's description. If you later want a real perpetual calendar, budget for service costs as well, since these movements need specialist attention every five to seven years.
