Short answer
A watch sold as a Lange 1 Tourbillon with reference 704.035 is almost never what the seller claims. The reference number is real, which is why the question keeps coming up in dealer listings and buyer forums, but the pieces carrying that number in the replica market come from generic cases and decorated automatic movements. The question cannot be answered from photos. It gets answered by matching three records at once: the case number, the movement number, and the dial and case combination that A. Lange & Söhne logged for that reference.

What the 704.035 Reference Covers
Lange built the Lange 1 Tourbillon in a short run of platinum references, and 704.035 sits inside that group. The watch is a 38.5 mm platinum case with a hand wound calibre, a one minute flying tourbillon shown through a cutout in the dial, an outsize date, and an off centre main dial with a separate small seconds. A listing that describes a 42 mm steel case, a screw down crown, or a self winding movement is not describing this reference at all. It is describing a case and movement made to look close from arm's length.
Top Best Guide to Finding Fake Lange 1 Tourbillon 704.035 Synonyms
Prerequisites
- Case number and movement number from the seller, in writing
- Clear close up photos of the caseback, the tourbillon cutout, the balance cock engraving, and the crown
- A route to A. Lange & Söhne service or a boutique that can pull factory records
Verification Procedure
- Ask the seller for the case number stamped on the caseback and the movement number engraved on the calibre.
- Request a photo of both numbers in the same frame, with the caseback removed and the movement visible.
- Send those numbers to Lange service and ask whether the reference, case number, and movement number belong together.
- Measure the case across the bezel and confirm a diameter near 38.5 mm with a thickness near 10 mm.
- Look at the tourbillon cutout and confirm a rotating carriage with a screwed balance cock, not a printed disc or a fixed cage.
- Check the outsize date and confirm two separate discs with a sharp dividing line and no printed date window frame.
- Wind the watch and confirm hand wound resistance through the crown, then confirm the stop seconds function on the tourbillon.
- Inspect the balance cock engraving under magnification and confirm freehand scroll work cut into the metal.
- Walk away if any single check fails, because a real 704.035 passes all of them.
Red Flags on Replica Listings
- Seller refuses to give the movement number or sends a stock photo of a movement
- Caseback engraving that sits shallow, with laser etching instead of deep stamping
- Blued screws that are painted rather than heat treated, showing a flat blue tone
- Balance cock engraving that looks cast or stamped, with soft edges and repeating patterns
- Movement described as automatic, or a rotor visible through the caseback
- Box and papers from a third party print shop instead of a Lange service record
- Price far under the platinum market range for a Lange 1 Tourbillon
Why the Reference Question Keeps Coming Up
Reference numbers travel faster than watches. A seller copies a number from a catalog or an auction result, attaches it to a replica, and the number does the selling. Buyers then search the reference, find real photos of a real watch, and assume the listing matches. It does not. Treat 704.035 as a record to be checked against the factory, not as a label that carries any proof on its own.
