There is no "Lange 2" in the A. Lange & Söhne catalogue, so a fake Lange 2 gold watch is almost always a counterfeit of the Lange 1 sold under an invented name. The same checks that expose a fake Lange 1 apply to any copy marketed as a Lange 2: solid 18k gold with correct hallmarks, a hand-engraved balance cock, and a signed, numbered movement.
Start With the Model Name
A. Lange & Söhne builds the Lange 1, Lange 1 Moon Phase, Lange 1 Time Zone, Saxonia, 1815, Datograph, and Zeitwerk. There is no Lange 2. When a listing uses that name, the seller has either invented a reference or renamed a Lange 1 to dodge searches for counterfeits. Treat the name itself as the first warning sign, then look at the metal and the movement.
Gold Is Hard to Fake Well
Genuine Lange cases come in 18k yellow, rose, or white gold, and in platinum. A counterfeit can plate a base-metal case or use gold-filled stock instead of solid gold. Plating wears through at the lugs, crown, and caseback edges after months of wear, showing a different colour underneath. Weight is another clue. Solid 18k gold is dense, so a real Lange 1 in gold has heft that matches its size, while a plated copy feels light in the hand and sounds thin when tapped.
Look for Hallmarks and Engravings
Real cases carry precious-metal hallmarks plus a case number, struck with sharp, even edges. Fake Lange 2 gold examples show shallow or uneven stamps, missing fineness marks, or hallmarks crowded into a spot where the maker does not place them.
Movement Finish Separates Real From Replica
The movement is the part no replica reproduces with any accuracy. On a genuine Lange, inspect:
- A hand-engraved balance cock with floral scroll, cut by one engraver, never a stamped pattern repeated across watches
- Screw-mounted gold chatons and heat-blued screws with a deep, even blue
- A Glashütte three-quarter plate in untreated German silver that tarnishes to a soft yellow tone over time
- Wide, straight Glashütte ribbing with clean edges between the stripes
On a counterfeit you see machine-stamped decoration, plated bridges, and screws that look painted blue rather than heat-blued. Rotor engraving is soft, and case screws show tool marks and uneven slots.
The Outsize Date and Dial Details
The Lange 1 outsize date sits in a double aperture at the top right of the dial. On fakes, the two date discs do not line up, the numerals are too thick, or the aperture is cut off centre. Under a loupe, genuine dial printing has crisp serifs and even spacing, including the "Made in Germany" mark. Hands on a real piece are polished with sharp bevels, not rounded from stamping.
Red Flags at a Glance
- A model name such as Lange 2 that does not exist in the brand's collection
- A price far below the scrap value of the gold in the case
- Stock photos or images lifted from auction listings
- No papers, no service records, and a seller who refuses a watchmaker inspection
- Gold colour that shifts between the lugs, buckle, and caseback
- Caseback engraving that is laser-etched instead of cut
Verify Before You Pay
Have an independent watchmaker open the case and test the metal with acid or X-ray fluorescence. Match the movement number against brand records, and ask for the original invoice. For any gold Lange, the metal value of the case sets a floor that no honest seller ignores, so a price below that floor tells you what to question first.
