Short answer
A "fake Lange 1 Tourbillon 704.035" is a counterfeit copy of a platinum A. Lange & Söhne Lange 1 Tourbillon. Every replica sold under that reference fails the same three tests: the tourbillon does not work as a tourbillon, the movement is not hand-finished to Saxon standards, and the case and dial proportions are wrong. If someone offers you a 704.035 at a fraction of market value, it is not a bargain. It is a counterfeit.
What reference 704.035 actually is
The Lange 1 Tourbillon belongs to the Lange 1 family, the off-center dial layout that A. Lange & Söhne launched in 1994 after the brand's relaunch. The tourbillon version adds a one-minute flying tourbillon visible through an aperture at the top of the dial, with a patented stop-seconds mechanism that lets the owner hack the tourbillon and set the watch to the second. The outsize date, the small seconds hand carried on the tourbillon cage, and the power reserve indicator sit in the same asymmetric arrangement as the standard Lange 1. Platinum is the usual case metal for this reference. Genuine examples trade well into six figures in US dollars on the secondary market.
Where replicas break down
- The tourbillon cage is often decorative or glued to a rotor-driven ring. It spins, but it does not regulate the watch.
- Finishing is stamped or laser-etched. Genuine bridges carry hand-applied Glashütte ribbing, polished bevels, and blued screws.
- Dial printing is fuzzy under magnification. The genuine dial has crisp, raised applied markers and a flawlessly aligned outsize date.
- Case thickness and lug curvature are off. Replicas usually wear thicker than the genuine piece.
- Engraving on the balance cock and the movement plate is shallow and mechanical in appearance.
Five checks you can run yourself
- Pull the crown to the setting position and watch the small seconds hand. If the cage keeps rotating, the stop-seconds mechanism is fake.
- Turn the watch over and inspect the tourbillon bridge under a loupe. Real hand-finishing shows slight, irregular polish lines, not uniform machine swirls.
- Compare the outsize date window to the dial aperture. On counterfeit dials the numerals sit low or touch the frame.
- Weigh the watch. Platinum is roughly twice the density of steel, and a correct 704.035 feels noticeably heavy for its size.
- Request the movement and case numbers, then verify them with an authorized A. Lange & Söhne boutique or a qualified watchmaker before any money moves.
Why a counterfeit is a bad trade
Counterfeit watches are illegal to import into the United States. U.S. Customs and Border Protection can seize shipments, and buyers who paid by wire usually recover nothing. U.S. Immigration and Customs Enforcement treats large-scale counterfeit trafficking as a federal offense, which means the seller carries criminal exposure and the buyer carries the loss of funds. Beyond the law, a counterfeit has no service path. Authorized watchmakers will not touch it, parts do not exist, and any local repair shop that opens a fake tourbillon will find a movement it cannot source components for. Resale value is zero.
Bottom line
A 704.035 is a hand-finished mechanical object with a working tourbillon and a patended stop-seconds system. A counterfeit is a case and dial built to look like one in photographs. Judge any offer by the movement, the finishing, and the paperwork, not by the reference number printed in an online listing.
