Quick answer
A replica Saxonia Tourbillon is a copy of the A. Lange & Söhne Saxonia case shape with a Chinese-made tourbillon movement inside. Street prices run from about $450 to $1,600. The case is gold-plated brass or 316L steel, not solid gold. The movement is a Seagull ST8000, ST8230, or a Dandong tourbillon, not a Lange caliber. No replica matches the hand finishing of the original. A genuine Saxonia starts near $20,000. A genuine Lange tourbillon sells above $100,000.
What the original is
A. Lange & Söhne builds the Saxonia in Glashütte, Germany. The Saxonia is a round dress watch. Case sizes are 38.5 mm and 40 mm in white gold, pink gold, or platinum. The dial carries applied markers and a small seconds subdial. The brand's model pages list tourbillon watches under the 1815, Lange 1, Richard Lange, and Datograph names. A Saxonia case with a tourbillon is not a standard catalog reference. Listings that use the name "Saxonia Tourbillon" often blend specs from two references. Ask for the reference number before you compare prices.
What the replica gets right
- Case diameter from 38.5 mm to 40 mm, close to Saxonia proportions.
- Sapphire on the front, sapphire or mineral glass on the back.
- Small seconds at 6 o'clock with applied markers.
- Hand-wound tourbillon cage that turns once per minute.
- Power reserve from 40 to 60 hours.
Where it differs
- Case metal. Gold plating at 3 to 5 microns over brass or 316L steel. Plating wears through at the lugs and crown within 12 to 24 months of regular wear.
- Movement. Seagull ST8000, ST8230, or Dandong. Beat rate 21,600 vph or 28,800 vph. Lange uses 21,600 vph.
- Finishing. No three-quarter plate. No hand-engraved balance cock. Replicas use machine polishing on bridges and screws.
- Dial text. The Lange signature and the "Made in Germany" line sit heavier on replicas.
- Weight. A gold Saxonia on a strap runs 70 to 90 grams. A plated replica runs 55 to 70 grams.
Price tiers
Entry tier: $450 to $700. Steel case, mineral glass, Seagull ST8000, printed dial.
Mid tier: $700 to $1,000. Plated case, sapphire, better dial printing, decorated bridges.
Top tier: $1,000 to $1,600. Thicker plating, closer dial color, alligator strap.
Genuine Lange tourbillons cost far more. Asking prices on the secondary market sit above $100,000 for most references.
Legal notes for US buyers
18 U.S.C. 2320 makes trafficking in counterfeit goods a federal crime in the United States. Personal use is not the focus of that statute, but US Customs and Border Protection can seize a shipment. Marketplaces such as eBay and Chrono24 remove counterfeit listings. Reselling a replica as a genuine watch adds fraud exposure.
Buyer checklist
- Ask for the reference number. Compare it with the Lange model page.
- Ask for movement photos. The genuine item has a three-quarter plate, blued screws, and an engraved balance cock.
- Ask for the weight in grams with the strap on.
- Ask for a macro photo of the dial text at 10x.
- Ask what the tourbillon cage does. One turn per minute is standard.
