Short answer
A. Lange & Sohne does not list a model named Lange 3. The brand makes the Lange 1, Grand Lange 1, Little Lange 1, Lange 1 Time Zone, Saxonia, 1815, Richard Lange, Datograph and Zeitwerk. A search for fake lange 3 101.03f joins a model name that does not exist with a reference string we could not match to any published Lange catalog entry. Replica sellers use strings of this kind to group listings on marketplaces.
Where 101.03F comes from
Lange 1 references start with 101. Published examples include 101.021, 101.022, 101.027 and 101.032. Lange reference numbers use digits after the decimal point. A trailing letter F does not appear in the reference format the brand publishes. Treat 101.03F as a seller code, not a factory reference.
If a listing shows 101.03F, ask for a caseback photo. On a real Lange, the reference number is engraved on the caseback next to the model number, and the movement number matches brand records.
What the real watch is
The Lange 1 is a 38.5 mm manual wind watch. Lange lists the L901.0 movement at 365 parts, 53 jewels, 21,600 vibrations per hour and a 72 hour power reserve. The dial carries an outsize date, an off centre main dial, a small seconds subdial and a power reserve indicator. The movement uses a three quarter plate in untreated German silver, screwed gold chatons and a balance cock with hand engraving.
How replica Lange 1 watches are built
- Case: plated brass or 316L steel with gold colour, not solid gold or platinum. Weight is lower than a gold Lange 1.
- Movement: Miyota 9015 or a Chinese automatic with decorative plates screwed on top. The real watch is manual wind.
- Date: printed or stamped discs with a font that differs from the Lange date font. The date does not jump at midnight in one step on many copies.
- Dial: applied markers on better copies, printed markers on cheap ones. Subdial spacing differs from the real 38.5 mm layout.
- Engraving: machine cut or laser etched. Hand engraving shows uneven cuts and tool marks under a loupe.
- Crystal: sapphire on mid and top tier copies, mineral glass on low tier copies.
Checkpoints
- Measure the case. 38.5 mm is the Lange 1 figure. Copies often run 39 mm to 41 mm and sit thicker than 10 mm.
- Weigh the watch. A gold Lange 1 head weighs much more than a plated copy.
- Wind it. A manual wind crown with a 40 turn span points to a real movement. Rotor noise points to an automatic.
- Check the date aperture. The Lange outsize date uses two separate discs and a specific font.
- Look at the balance cock. Hand engraving varies. Stamped engraving repeats.
Price ranges
Replica Lange 1 style watches sell from about $150 to $900. Used gold Lange 1 watches trade in the $25,000 to $40,000 range on the secondary market, and prices move with metal and condition. A price under $1,000 for a claimed gold Lange 1 is a copy.
What we could not confirm
We found no A. Lange & Sohne model called Lange 3 and no reference 101.03F in brand material. If a seller cites that string, ask for the model name, the case metal and the movement number. A real Lange has a movement number that matches brand records.
