The replica Lange 2 perpetual is a counterfeit version of an A. Lange & Söhne perpetual calendar watch, and the most important thing to check is whether the calendar subdials actually work. A genuine perpetual calendar tracks date, day, month, moon phase and leap year without correction until 2100. Most replicas only copy that layout on the dial, so knowing the difference separates a serious build from a decorative one.
What "Lange 2 Perpetual" Usually Refers To
The phrase is buyer shorthand, not an official model name. Lange's catalog uses designations such as Lange 1 and Lange 1 Perpetual Calendar. People searching for a Lange 2 perpetual generally mean the second-generation look of that family: the asymmetric dial with the outsize date at the upper right and the time display on the left.
When a seller lists a replica Lange 2 perpetual, ask which reference they copied and what the case measures. The Lange 1 Perpetual Calendar runs around 41.9 mm wide. A fake that arrives at 38 mm will sit on the wrist very differently, and the outsize date will look cramped against the rest of the layout.
The Dial Layout to Verify
Compare the watch in front of you against these features:
- Outsize date aperture at the upper right, built from two separate date discs
- Main time dial on the left with hours, minutes and small seconds
- Day-of-week and month indications, usually on rings or small subdials
- Moon phase aperture with a clean, readable disc
- Leap year indicator, often small and easy to overlook
- Day and night indicator on some versions
If the leap year display is missing, painted on, or never changes, the watch is not a perpetual calendar. It is a calendar-style watch with a perpetual face. That distinction matters if you want the function and not only the look.
Movement: The Part That Sets the Price
Three broad tiers show up in the replica market, and the movement is what separates them:
- Quartz builds. Lowest cost. The seconds hand ticks, and calendar indications often sit frozen.
- Modified Asian automatic. Subdials move, but the calendar is usually annual or complete rather than perpetual, so February needs manual correction.
- Clone and high-grade automatic. Closest to the original layout and function, and the tier wholesalers charge most for.
Ask the seller for a short video with the crown pulled and the pushers worked one at a time. On a real perpetual module the date, day, month and moon phase advance in sequence and stay in sync. Also ask for a close shot of the balance cock. Lange hand-engraves that part, so a stamped or laser-etched pattern is a clear step down in finishing.
Case, Dial and Hands
Case material affects how the watch ages. 316L steel is common and fine for daily wear. 904L steel resists scratches better and takes a brighter polish. Gold-plated cases vary a great deal in plating thickness, and thin plating shows wear at the lugs and crown within months.
On the dial, look at the printing under magnification. Clean, sharp text with no bleed is a good sign. Applied markers should sit level and catch light evenly. Blued or heat-treated hands should show a consistent tone rather than a painted blue that looks flat in daylight. Sapphire crystal with an anti-reflective coating is standard on better builds. Mineral glass scratches and reflects more.
Quality Tiers and What to Expect
Tiers differ in movement, crystal, case finishing and dial work, not in the logo on the dial. A top-tier replica Lange 2 perpetual should offer a working perpetual or annual calendar, sapphire on both sides, a properly finished case with crisp edges, and a dial that holds up under a loupe. Mid-tier builds often look correct at arm's length but reveal painted subdials or a mineral crystal up close. Entry-tier pieces are best treated as fashion watches.
Vetting a Wholesale Supplier
- Request live photos and a dated timestamp, not catalog images
- Ask for a movement photo with the caseback removed
- Confirm the return window and what it covers
- Ask whether spare parts and straps are stocked
- Check how the seller handles shipping and customs questions
- Read buyer feedback across more than one forum or marketplace
Quick Pre-Purchase Checklist
- Confirm the reference being copied and the case diameter.
- Verify that the calendar indications advance and stay synced.
- Check the leap year display works, not just exists.
- Inspect dial printing, marker alignment and hand colour.
- Confirm sapphire crystal and a signed caseback if the reference has one.
- Get the warranty and return terms in writing before payment.
A replica Lange 2 perpetual can look convincing on the wrist, but the calendar function is where most fakes fall apart. Decide first whether you want the mechanism or the appearance, then match the tier and the supplier to that answer.
