Buy the Watch, Not the Bargain
There is no legitimate low-cost A. Lange & Söhne supply. The manufacture builds a few thousand watches a year by hand in Glashütte, and every one is recorded by serial number at the factory. When a listing shows a Lange 1, Saxonia, or Datograph for a few hundred dollars, the piece is counterfeit, and the money is gone the moment it ships. Treat any price far below the pre-owned market as a warning, not an opportunity.
Step-by-Step: Verify Before You Negotiate
- Ask the seller for the full reference number and case serial in writing, plus a clear photo of the caseback engraving.
- Check that reference against the official catalogue to confirm the metal, dial, and movement combination existed for that production year.
- Request a video of the running movement through the sapphire caseback, showing the balance and the sweeping seconds hand.
- Ask for service invoices from a Lange boutique or an authorized service partner.
- Send the serial number to A. Lange & Söhne customer service and request an archive extract or certificate of origin.
- Pay only through a channel that allows a chargeback or an escrow release; a wire to a private seller leaves no recourse.
- Have an independent watchmaker inspect the movement inside the return window, before funds clear.
Parameters That Move the Price
- Reference and complication: a time-only Saxonia sits at the bottom of the range, while a Lange 1, Zeitwerk, or Datograph sits far above it.
- Case metal: platinum and rose gold trade higher than white gold variants.
- Box and papers: a full set with the original guarantee booklet usually adds a premium over a loose watch.
- Service history: documented work at Glashütte protects value; unknown history can mean a five-figure repair.
- Condition: unpolished cases with sharp lugs hold value better than heavily refinished examples.
Pitfalls That Cost Buyers Money
- Marketplace listings using stock photos at a price well under five figures.
- Sellers who refuse a movement video or push friends-and-family payment.
- Blank or open guarantee cards, which complicate both resale and future servicing.
- Soft dial printing, misaligned date windows, or rotor finishing that does not match the movement.
Price is the last thing to check, not the first. Confirm the serial, the movement, and the paperwork, then compare the asking figure against recent sales of the same reference in the same condition. A real Lange costs real money, and that gap is the most reliable counterfeit detector you have.
