A fake Datograph 912.021 is a replica of the A. Lange & Söhne Datograph, the German maker's hand-wound flyback chronograph with an outsize date. The reference code points to one case and dial combination inside the Datograph line, so the copy you receive depends on which factory built it and which photos the seller copied. Prices for a fake Datograph 912.021 run from about $150 for quartz lookalikes to $700 or more for hand-wound copies with a working chronograph and date.
This guide covers what the reference means, which details separate a solid copy from a weak one, and what to confirm before you send money.
What is the A. Lange & Söhne Datograph 912.021?
The Datograph is A. Lange & Söhne's flagship chronograph, introduced in 1999 with an in-house column-wheel movement. It pairs a flyback chronograph with a big date window, two subdials, and a case built in platinum, gold, or steel depending on the version.
Reference numbers in the Datograph family cover several generations, sizes, and materials. Some codes belong to the first-generation model, others to the Up/Down or Perpetual variants. If a seller lists 912.021, compare the listing photos against the real reference, and ask the seller to confirm case size and movement before you treat the number as accurate.
Which details define the Datograph look?
- Outsize date at 12 o'clock, built from two separate discs.
- Small seconds at 8 o'clock and a 30-minute chronograph counter at 4 o'clock.
- Two chronograph pushers plus a crown, with the date set through a pusher at 10 o'clock.
- Hand-wound movement visible through a sapphire caseback.
- Roman numerals or baton markers, depending on the dial variant.
What should you check on a replica Datograph 912.021 before buying?
Movement type
Ask whether the chronograph runs on a hand-wound movement or a quartz module. Quartz versions move the chrono hands but feel light in the hand and often skip true running seconds. Hand-wound Seagull ST19 movements and similar clones give the right pusher feel and never need a battery.
Case size and finishing
Datograph cases measure 39mm to 41mm depending on generation, so a copy that comes in at 43mm wears like a different watch. Check the bevels on the lugs and the polish on the pushers. Sharp edges and cloudy brushing point to a cheap build.
Dial and the outsize date
The date should snap over at midnight instead of drifting across the window. On weak replicas the two date discs sit on different levels or print in mismatched fonts. Ask for a short video of the date change before you buy.
Caseback and engraving
Replica casebacks carry engraved text, not real hallmarks, so judge the print quality. Engraving depth and font weight vary between factories, and blurry text signals the bottom tier. If the seller shows one dim caseback photo, request more.
How much does a fake Datograph 912.021 cost?
Price tracks movement type, case material, and finish quality. Wholesale listings sit in three broad bands.
- $120 to $200: quartz movement, printed dial, mineral glass, decorative date.
- $250 to $400: automatic or hand-wound chronograph, sapphire crystal, working date.
- $500 to $800 and up: clone hand-wound movement, sapphire caseback, closer dial printing and case finishing.
Past that top band you pay for factory name and scarcity, not for a jump in quality. Compare two or three sellers in the same tier before you commit.
What flaws show up in cheap Datograph replicas?
- Date discs that misalign or leave a gap at the center.
- Chronograph seconds hand that stutters or resets past zero.
- Subdials spaced too far apart or too close to the center.
- Case thickness well over the real 13mm profile.
- Faint or wrong-font engraving on the caseback.
How do you vet a replica Datograph seller?
Ask for a timestamped photo or video of the exact unit you will receive. Sellers who reuse factory stock images cannot show the watch in hand. Pay with a method that offers buyer protection, and get the return window in writing before you transfer funds.
Check whether the product page lists movement type, case size, and glass material. Missing specs point to a lower tier. A seller who answers technical questions about the movement is a better bet than one who replies with pricing alone.
Frequently asked questions
Does a replica Datograph 912.021 have a working chronograph?
Mid-tier and high-tier copies do. Quartz versions often run the chrono hand as decoration that resets to zero without a real elapsed-time mechanism. Confirm the movement type before purchase.
Can a watchmaker tell a replica Datograph from the real thing?
Yes. A watchmaker will spot the movement finishing, the engraving, and the case construction in moments. The replica market is about look and feel on the wrist, not about passing an inspection bench.
Do replica Datograph watches hold value?
No. Replica watches resell for a fraction of what you paid and carry no collector market. Buy one as a wearable, not as an asset.
Is a homage the same as a fake Datograph?
Not quite. A homage borrows a style without copying logos or reference numbers. A fake Datograph 912.021 copies the branding, the reference, and the dial layout.
Bottom line
Pick the movement first, then the case size, then the finish. A hand-wound copy with a working date and a sapphire caseback costs more at checkout and less in frustration. Skip any listing that hides the movement type or refuses a live video.
