Short answer
A fake Saxonia Automatic gives itself away at the movement. The genuine watch uses the L086.1 caliber, a 38.5 mm gold or platinum case, applied gold indexes, and hand finishing that no counterfeit factory reproduces. Copies show laser etching in place of hand engraving, plated base metal in place of solid gold, and case sizes of 40 mm or more. Check the movement first, the case metal second, and the dial last.
What you need before you start
- A 10x loupe and a bright, diffused light
- The reference number of the watch you are viewing
- Calipers or a ruler, and a digital scale if you can weigh the head
- Clear photos of the dial, caseback, crown, and movement, if you cannot handle the watch
- The seller documentation: box, papers, service records, and original invoice
Step-by-step inspection
- Measure the case. A modern Saxonia Automatic measures 38.5 mm across and about 9 mm thick. Most copies are 40 mm or wider and sit taller on the wrist. Case size alone rules out a large share of fakes.
- Weigh the head. A solid gold case feels dense in the hand for its size. A gold-plated steel or brass copy feels light and hollow. A tungsten copy feels heavy but fails the caseback and dial checks below.
- Look at the dial print. Genuine printing is crisp with clean edges, and the indexes are solid gold with polished facets. On fakes, the print looks soft or uneven, the indexes sit crooked, and the markers reflect light in a flat way.
- Study the hands. Real hands have polished bevels and a sharp tip. Fake hands look flat, painted, or plated, and the seconds hand sits at the wrong height above the dial.
- Test the outsize date, if the reference has one. The date runs on two separate discs. The numerals line up, the jump happens at midnight, and the aperture edges are clean. A copy uses one printed disc or a module that sits proud of the dial.
- Inspect the caseback engraving. Reference number, metal, and maker marks are cut deep and sharp. Laser-etched text on a fake looks shallow and grey.
- Check the metal stamps. Gold and platinum cases carry a fineness stamp and a hallmark. A case with no stamp, or a stamp that does not match the metal color, is plated.
- Examine the lugs and bevels. Lange cases have tight, mirror-polished edges and sharp lug lines. Fake cases show rounded edges and uneven brushing.
- View the movement. Ask for a clear photo with the caseback removed, or have a watchmaker open it. The genuine caliber shows Glashütte ribbing, heat-blued screws, gold chatons, and a hand-engraved balance cock. Fakes show laser etching, flat plates, and a rotor that hides a generic automatic movement.
- Treat the strap and buckle as weak evidence. Straps get replaced, so a signed buckle never proves the watch is real.
- Review the paperwork. Box, papers, and service records should match the reference and the serial number. Copies often ship with documents that do not line up.
- Compare the price. A gold Saxonia Automatic holds value on the secondary market. An offer at a fraction of that value is not a bargain, it is a copy.
Where fakes fail
- Movement finishing: laser etching and printed text instead of hand engraving
- Case metal: plated steel or brass with no hallmark
- Case size: 40 mm and up instead of 38.5 mm
- Dial: soft print, glued indexes, flat reflections
- Outsize date: single disc or a raised module
- Documentation: mismatched serial numbers and missing service history
When to walk away
Stop the inspection if the seller refuses an open caseback, if the movement cannot be photographed, or if the price sits far below the market. No dial, strap, or box detail makes up for a movement that is not a Lange caliber. If you cannot confirm the movement, treat the watch as a fake and move on.
