The short answer

A replica Lange 1 Tourbillon is a counterfeit copy of a hand-wound watch built by A. Lange & Söhne in Glashütte, Germany. Lange makes no replica of its own product and licenses the name to no other factory. Selling, buying for resale, or importing these copies into the United States is against federal law. No replica contains a Lange movement, and no replica carries a serial number that the company will confirm.

The original: Lange 1 Tourbillon

A. Lange & Söhne launched the Lange 1 in 1994, four years after Walter Lange restarted the company. The off-center dial, the outsize date, and the power reserve indicator became the house signature. The Lange 1 Tourbillon joined the line in 2000.

The 2000 model used a platinum case of about 38.5 mm. Inside sat the hand-wound calibre L961.1: a one-minute tourbillon with a stop-seconds device, a patented mechanism that halts the balance when the crown is pulled, so the watch can be set to the second. Lange described it as the first series-produced wristwatch to pair a tourbillon with stop-seconds. The company does not state a production total for the early platinum version, and later versions arrived in other case metals.

Finish is the part copies miss. Lange engraves the balance cock by hand with a floral pattern, sets screwed gold chatons, and cuts a Glashütte three-quarter plate with ribbing. A photo of the movement through a display back shows all three.

What the copies contain

Counterfeit sellers sort copies into grades and label them "Swiss made" or "1:1." The labels carry no standard meaning. Most copies run Chinese-made movements. A small number use a real Chinese tourbillon movement, such as the Seagull ST8000 series. That is a working tourbillon, but a different design from the Lange. Other copies install a rotating cage with no escapement inside it, so the part turns for show.

The outsize date is a common tell. Lange builds the big date from two separate discs, one for the tens and one for the units, driven by a patented mechanism. Many copies print the date on one disc, or use two discs that sit at different heights with different font weights.

Case metal is another gap. Lange stamps its cases, then finishes the surfaces by hand. Copies use plated brass or 316L steel with a polished coating. The plating wears through at the lugs and the caseback edge.

Law in the United States

18 U.S.C. § 2320 makes trafficking in counterfeit goods a federal crime. A first offense carries a prison term of up to 10 years. Civil claims sit under the Lanham Act, 15 U.S.C. § 1114 and § 1117. Statutory damages run from $1,000 to $200,000 per counterfeit mark per type of goods, and up to $2,000,000 if the court finds the infringement willful.

Import rules are separate. Under 19 U.S.C. § 1526(e), goods that bear a counterfeit mark recorded with U.S. Customs and Border Protection are subject to seizure and forfeiture. CBP lists watches among the top seized categories by value.

For a single buyer, the frequent outcome is a seized package and no refund. The seller collects payment first. This section describes the rules. It is not legal advice.

Value and resale

Original Lange 1 Tourbillon watches trade at auction in the six-figure USD range. Reference number, case metal, condition, and the presence of box and papers move the result. Auction totals shift from sale to sale, and I have no current figure to quote. Copies have no resale market. Christie's, Sotheby's, and Phillips do not accept counterfeit watches, and marketplace platforms block listings for them.

Checks before you buy

• Serial number. Lange's service department handles authenticity questions and can check a number against its records.
• Movement photo. Hand engraving on the balance cock and gold chatons do not appear on copies.
• Date construction. Two discs, two font sets, and a visible gap at the division are correct.
• Movement name. Ask the seller to name the calibre. A named Chinese tourbillon calibre is a real tourbillon, not a Lange part.
