Quick answer
A fake A. Lange & Söhne watch carries Lange markings but was not built in Glashütte, Germany. A genuine watch leaves the workshop with a hand-engraved balance cock, screwed gold chatons, a Glashütte three-quarter plate, and a serial number that matches its certificate. Most fakes use a stock Asian movement, printed or laser-etched decoration, and a gold-plated case. Price answers the question first. A new Saxonia starts near $20,000 USD and a Lange 1 near $45,000 USD. A listing at $200 to $900 is not a watch from Saxony.
Production numbers set the baseline
Ferdinand Adolph Lange founded the company in Glashütte in 1845. The East German state expropriated the family firm in 1948. Walter Lange restarted the brand in 1990, and the first new collection arrived in 1994 with four models: Lange 1, Arkade, Saxonia, and Tourbillon Pour le Mérite. Annual output runs in the low thousands of watches. Rolex and Omega build millions. That gap is why counterfeits exist.
Movement checks
- Balance cock engraving: every genuine Lange movement has a balance cock engraved by hand with flowers, waves, or requested initials. Most fakes show laser etching, a stamp, or nothing.
- Finish: Glashütte ribbing on the three-quarter plate, perlage on the mainplate, blued screws, and chamfered edges. Under a loupe, most counterfeits show machine stripes and sharp edges.
- Gold chatons: gold rings around the jewel bearings, each held by two or three screws. Fakes glue in gold-colored rings with no screws.
- No quartz: Lange has never built a quartz watch. A ticking second hand means the movement is not a Lange.
- Movement size: a real Lange movement fills the case. Fakes use a small generic movement plus a spacer ring, which leaves a wide gap around the movement.
Dial and case checks
- Outsize date: the Lange 1 uses two independent discs and a patented mechanism. Fakes show one disc, uneven gaps between the numbers, or a date that does not jump at midnight.
- Printing: the signature sits at the top of the dial with consistent letter weight and spacing. Fakes show thick letters, a crooked baseline, or a shifted logo.
- Hands: heat-blued steel with a polished bevel on most models. Fakes use painted blue steel.
- Case metal: most cases are platinum or gold. Platinum is hallmarked "Pt950". Gold is hallmarked "750" or "Au750". Steel Lange cases exist but are rare, and most fakes are steel.
- Caseback: display backs are standard on most references, with sapphire that is antireflective on both sides. Fake casebacks are thick and hold plain glass in a glued rim.
Markings, serials, and papers
The caseback carries the brand name, the metal hallmark, and a serial number. The movement carries a second number on the three-quarter plate. Both numbers appear on the certificate. Lange keeps service records by serial number, so a boutique or an authorized service center can confirm a watch against its own files. Most fakes have no serial, a duplicate serial, or numbers stamped off-center. Papers are photocopies in many cases.
Price and market signals
Lange sells through its own boutiques and a small set of authorized retailers. There is no discount channel and no factory outlet. Used prices hold near retail for common references and above retail for rare ones. A listing below market, a seller who avoids photos of the caseback, or a new watch with no box and no certificate points to a counterfeit.
Legal note
In the United States, trafficking in counterfeit goods is a federal crime under 18 U.S.C. § 2320, and U.S. Customs can seize counterfeit watches at import.
What a fake cannot copy
The balance cock engraving takes an engraver hours per watch. The outsize date mechanism is patented and built in-house. The three-quarter plate, gold chatons, and hand-finished bevels come from one workshop in Glashütte. A counterfeit factory copies the outside. It does not rebuild the inside.
