A replica Saxonia Tourbillon is a Chinese-built watch that copies the case and dial layout of A. Lange & Söhne's Saxonia line and puts a working one-minute tourbillon at 6 o'clock. Street prices run from about $350 for a basic steel model to $1,500 for a hand-wound tourbillon with a decorated plate and sapphire caseback. The one thing that decides whether a copy is worth the money is the movement: a real cage that makes one full turn per minute, not a decorative ring glued over an ordinary balance wheel.
What the Genuine Watch Sets as the Standard
The Saxonia family uses a slim round case, a clean dial with thin baton hands, and applied markers. Genuine Lange tourbillons are hand-finished, use a one-minute flying tourbillon, and add a stop-seconds device on some references so the watch can be set to the second. Replicas copy the outside and the dial text. They do not copy the finishing, the hairspring, or the escapement quality, and no copy holds rate like the original.
Inspection Steps Before You Pay
- Ask the seller for a video of the running watch with the tourbillon cage in frame.
- Time one full rotation of the cage with a stopwatch. It should take 60 seconds, not 30 and not 120.
- Count balance beats in a 15-second audio clip. A 21,600 vph movement gives 90 beats, a 28,800 vph movement gives 120.
- Request the case diameter and thickness measured with calipers. Most copies run 39 to 41 mm wide and 11 to 13 mm thick, against 38.5 mm wide and about 10 mm thick for a Saxonia Automatic.
- Study the dial printing under magnification. The logo font, the spacing of the Saxon lettering, and the country-of-origin line are the first places cheap copies fail.
- Check the caseback screws and engraving. Genuine Lange uses blued screws and a hand-engraved balance cock, and no replica reproduces either.
- Wind the watch fully, set it down, and let it run. A decent Chinese tourbillon reaches 40 to 50 hours of reserve. A weak one dies in 8.
- Time it over 24 hours in two positions before you accept delivery. Anything past 30 seconds a day needs regulating or a return.
Movement Options
Most replicas use a hand-wound Chinese tourbillon, often built on a Seagull or Hangzhou ébauche, running at 21,600 vph with a 40-hour power reserve. Others use an automatic micro-rotor tourbillon. Hand-wound versions are thinner, easier to regulate, and cheaper to replace. A tourbillon service in the US costs more than the watch, so treat the movement as a disposable part and budget for a swap rather than a repair.
Case and Finish
Cheap copies use gold plating that wears through in months at the crown and lugs. Better ones use PVD or solid stainless steel. Look for a sapphire crystal with coating on both faces, a properly seated caseback, and a leather strap with real stitching. A display back is worth having because it lets you see the cage from behind and confirm which movement you actually received.
Legal and Practical Notes
Counterfeit watches are illegal to import into the United States. Customs and Border Protection can seize a shipment, and the buyer loses the money with no recourse. Domestic sellers cut that risk but charge more. No replica carries a valid manufacturer warranty, and repair options are limited to independent watchmakers who work on Chinese movements.
