Short answer
A. Lange & Söhne has never made a watch called the Lange 2. The name does not appear in the Glashütte catalog, and reference 258.026 does not match any Lange model I could verify in public catalogs or auction records. Search results for "fake lange 2 258.026" lead to replica listings. The watch those listings copy is the Lange 1.
How Lange reference numbers work
Lange uses a three-digit block plus a three-digit suffix. The Lange 1 sits in the 101 block. The Grand Lange 1 sits in the 115 block. The Lange 1 Moonphase sits in the 109 block, the Lange 1 Time Zone in the 116 block, the Datograph in the 403 block, the Langematik in the 308 block. The 258 block is not attached to a Lange 1 variant in the sources I checked. A seller who calls 258.026 a factory number has not read the catalog.
Where the name Lange 2 comes from
Two explanations appear in listings. Some sellers shorten model names to avoid brand filters on marketplaces. Others use "Lange 2" as a loose label for the Grand Lange 1, which measures about 41 mm across, against 38.5 mm for the Lange 1. If a listing shows an off-center dial, an outsize date in the top right, and a power reserve arc, it copies the Lange 1 layout, not a second generation.
What the real Lange 1 is
- Case: 38.5 mm across, 9.8 mm thick. Yellow gold, white gold, rose gold, or platinum.
- Dial: main time dial off-center at 9 o'clock, outsize date at 1 o'clock, small seconds at 4 o'clock, power reserve indicator at 3 o'clock.
- Movement: hand-wound caliber L901.0, 72-hour power reserve, three-quarter plate in untreated German silver, hand-engraved balance cock, screwed gold chatons.
Where copies fail
Three checks catch most fakes. First, the movement. The L901.0 is hand-wound with no rotor. A display back that shows a rotor means an automatic movement, so the watch is not a Lange 1. Second, the power reserve hand. On the genuine watch it tracks the mainspring. Reports on low-cost copies describe that hand as fixed. Third, case size. Copies often measure 40 mm to 42 mm because they house a stock automatic movement, and the added width changes the dial proportions.
Price
Genuine Lange 1 watches trade between about $25,000 and $40,000 on the secondary market, depending on metal, box, and papers. Replica listings under the 258.026 label ask $200 to $800. Lange does not service fakes, and no parts exist for them. Lange does not publish an online serial lookup. Verification goes through its service center, which checks a serial number against factory records.
Before you buy
- Ask for the reference stamped on the caseback. Compare it with the Lange catalog.
- Ask for photos of the movement through the display back.
- Ask for a caliper photo of the case diameter.
- Ask what movement is inside, by name and caliber number.
