What Is a Fake Lange 2 Perpetual?

A fake Lange 2 perpetual is a replica of the A. Lange & Söhne Lange 1 Perpetual Calendar, the German brand's flagship calendar watch. The "Lange 2" label comes from buyer shorthand and search terms, not from the brand itself. The real model line is the Lange 1, and replicas copy its off-center dial, outsize date, moonphase, and leap year hand for a small share of the six-figure original.

This guide covers what the genuine watch does, what the copies get right, and where they fall apart.

Which Real Watch Does the Copy Target?

A. Lange & Söhne released the Lange 1 Perpetual Calendar in 2021 with caliber L021.3. It moves the time dial off-center, adds a retrograde month ring, an outsize date, a moonphase, and a leap year indicator, and ships in gold cases around 42 mm.

An earlier model, the Lange 1 Tourbillon Perpetual Calendar from 2012, carries the same calendar functions plus a tourbillon. Replica makers borrow details from both.

• Off-center main dial with the outsize date near the top
• Retrograde month ring along the outer edge
• Moonphase aperture with a gold disc on the original
• Small leap year hand beside the seconds subdial
• Hand-engraved balance cock and Glashütte ribbing on the movement

What Movement Sits Inside a Replica?

Movement grade is the biggest split in the replica market. Price tracks movement quality far more than dial quality.

Quartz builds

Entry copies run on quartz with decorative plates screwed over the battery. The calendar is printed or driven by a small stepper, so the month, moonphase, and leap year never move. These sell for under $200.

Automatic builds with an add-on calendar plate

Mid-tier copies use a Miyota or Seiko NH movement and stack a calendar module on top. The month ring advances, but the leap year often needs a manual push. Thickness grows because the module sits above the base movement.

Modified automatics with working perpetual gearing

Top replicas modify an ETA clone or a custom 28,800 vph movement so the calendar tracks 28, 30, and 31 day months plus February in leap years. Count on $1,200 and up, and expect a case that sits deeper than a genuine Lange.

How Do You Spot Flaws on a Fake Lange 2 Perpetual?

Compare the copy against official photos at the same angle. Most flaws show up within minutes.

• Dial printing: genuine text is thin and crisp. Copies show thick or doubled print.
• Outsize date: the two discs on the original snap over in one jump and sit flush. Copies show gaps and slow flips.
• Moonphase disc: real ones use a gold disc with hand-finished stars. Copies use printed foil.
• Hands: genuine hands are gold or blued steel with beveled edges. Copies show stamped edges and dull surfaces.
• Case profile: a stacked calendar module adds depth. Measure thickness against the reference number.
• Caseback engraving: text on the original is deep with defined edges. Laser etching looks shallow and gray.
• Movement finish: look for Glashütte ribbing, blued screws, and a hand-engraved balance cock. Copies use printed stripes.

What Specs Should You Ask For?

A seller who knows the product can answer these in one message. Vague replies point to a dropshipper with no stock on hand.

• Case diameter and thickness in millimeters
• Movement name and beat rate
• Crystal type (sapphire versus mineral) and whether it has anti-reflective coating
• Case material (316L steel, 904L steel, or plated)
• Weight on a scale, in grams
• Water resistance rating and crown type

What Does a Replica Cost?

• Under $200: quartz, static calendar, plated case, mineral glass.
• $250 to $600: automatic base movement, partial calendar function, 316L steel, sapphire on some models.
• $700 to $1,500: cleaner dial work, closer case profile, working month and moonphase.
• $1,500 to $4,000: modified movement with true perpetual gearing, plus gold plating or solid gold cases on rare builds.

A genuine Lange 1 Perpetual Calendar trades in the low six figures, so even the top replica sits at a tiny fraction of that number. The gap drives the market, and it is also why finishing shortcuts appear.

Does the Calendar Function Actually Work?

On most replicas, no. A true perpetual calendar handles the 28 day February and the 30 day months on its own until 2100, when the Gregorian rule skips a leap year.

Many replica builds ship as complete calendars. You correct the date with a pusher after every short month. Forcing a pusher near midnight can strip the gear teeth.

If a listing claims true perpetual function, ask for video of the date flipping at month end. Sellers with working gearing will send it.

Is Buying One Legal in the US?

Selling counterfeit watches is illegal in the United States, and US Customs can seize counterfeit goods shipped from abroad. Buying for personal use sits in a gray zone, but the shipment can still be stopped and destroyed. That risk belongs to the buyer, not the seller.

Questions Buyers Ask

Will a watchmaker service a replica Lange perpetual?

Most authorized service centers refuse replica work, and the brand will not touch a counterfeit. Independent watchmakers often take the job, though parts for modified movements can be hard to source.

Is "first copy" the same as a fake Lange 2 perpetual?

Yes. "First copy", "1:1 replica", and "super clone" are market terms for the same product tier. None of them mean the watch came from Glashütte.

How long does a replica perpetual calendar last?

Quartz builds run for years with battery changes. Mechanical copies with a stacked module wear on the calendar plate, and many need service within three to five years.

What should I confirm before paying?

Ask for photos of the actual watch, a video of the date change, a clear movement shot, and a written return window. Sellers who send stock photos only are a risk.

Bottom Line

A fake Lange 2 perpetual can look close to the real Lange 1 Perpetual Calendar from two feet away. Up close, the differences land in the date discs, the moonphase, the case depth, and the movement finish.

Pay for the tier that matches what you want. If the calendar functions matter, budget for a modified movement. If the look matters more, an entry automatic does the job.
