Short answer
A fake Lange 1 Time Zone is a replica of the A. Lange & Söhne Lange 1 Time Zone, a hand-wound watch with two time zones and an outsize date. The genuine watch uses the in-house calibre L031.1 and a 72-hour power reserve. No replica at the first copy price level uses that movement. Most replicas pair a base movement from China or Japan with a decorative plate on top. The dial can be copied. The mechanics behind the dial cannot.
What the genuine watch does
A. Lange & Söhne launched the Lange 1 Time Zone in 2005. The case measures 41.9 mm across. The dial carries a main time display on the left, an outsize date at the top right, a second time zone dial on the right, a power reserve indicator, and a rotating city ring with 24 city names. A pusher at 8 o'clock advances the city ring. A day/night disc sits inside the second time zone dial. The movement reserves 72 hours of run time at full wind.
Where replicas diverge
- Case size. Replicas land at 40 mm or 42 mm. The genuine case is 41.9 mm.
- Date. Genuine uses two date discs with a cross-jump mechanism. Replicas show thin numerals, uneven spacing, or a printed date.
- City ring. Genuine lists 24 cities in a set order. Replicas repeat names or misspell them.
- 8 o'clock pusher. Genuine advances the city ring. On many replicas the pusher does nothing.
- Power reserve. The genuine needle tracks the mainspring. Replica needles sit on a printed scale.
- Caseback. Genuine shows a hand-engraved balance cock, blued screws, and screwed gold chatons. Replicas show stamped plates and screws that hold nothing.
Case metal and weight
Genuine Lange 1 Time Zone cases come in yellow gold, white gold, rose gold, and platinum. A gold case weighs more than a plated brass or steel case of the same size. Plated cases show wear at the lugs and caseback edge after contact with skin and sweat. Replica listings do not state plating thickness. No public data confirms plating specs on these products.
Legal status in the United States
Trafficking in counterfeit goods is a federal crime under 18 U.S.C. § 2320. A first conviction carries up to 10 years in prison and a $2,000,000 fine for an individual. Trademark owners can also sue for damages under the Lanham Act. U.S. Customs and Border Protection seizes counterfeit watches at ports of entry. The personal-use exemption that applies to gray-market goods does not cover items with a counterfeit mark.
Market context
A. Lange & Söhne produces a few thousand watches per year. That output is a fraction of Rolex or Omega volume, and the replica supply of Lange models reflects it. Replica Lange 1 Time Zone listings are fewer than replica Submariner or Speedmaster listings. Fewer options exist for case metal, dial color, and movement type. Figures on replica Lange production are not published.
