A fake Lange 2 Perpetual 725.038 is a replica perpetual calendar wristwatch sold under a seller catalog code, not an official brand reference. The number 725.038 identifies a listing inside a replica catalog, so the same build often appears under different codes from different dealers. What decides quality is the movement, the working calendar module, and the case and dial finishing, not the SKU printed on the order form.
Why the listing says "Lange 2"
A. Lange & Söhne does not sell a model called the Lange 2. The brand's signature outsize date and perpetual calendar design sits in the Lange 1 family, so a watch named "Lange 2 Perpetual" in a listing usually points to a Lange 1 Perpetual Calendar style build. Sellers rename products to avoid direct trademark use in titles, which is also why the same watch can be listed as "Lange Perpetual" or "Perpetual Calendar 725" somewhere else. Read the name as a description of the look, not a statement about origin.
When you search for the fake Lange 2 Perpetual 725.038, you are hunting one specific catalog entry: a perpetual calendar replica with a moon phase, a day and month display, and a double-aperture date.
What a perpetual calendar has to do
A real perpetual calendar tracks uneven month lengths and the leap year cycle without manual correction, using a program wheel and lever set that rotates once every four years. The genuine watch behind this style runs a self-winding caliber with the calendar built into the movement itself. That detail matters to buyers because the calendar is the hardest part to replicate.
- Month length: February must roll to 28 or 29 days on its own.
- Leap year: the leap indicator should advance once every four years.
- Moon phase: the disc should move in small, steady steps, not jump or lag.
- Date change: the double date should snap at midnight, not drift across several hours.
Movement tiers you will see in replicas
Most listings fall into three groups. Knowing which one you are buying prevents most disappointments.
- Quartz with a decorated plate. The calendar is usually a printed dial with decorative subdials. Nothing functions except the hands.
- Automatic clone with a calendar overlay. A modified 2824 or 2892 style automatic drives a bolted-on day, date, and moon phase module. Some functions work, the perpetual correction usually does not.
- High-end build with a proper module. The closest tier. The calendar advances correctly for month lengths, bridge and screw finishing is hand-worked, and the movement imitates an in-house style caliber.
Specs to confirm before you order
Ask for these in writing. A seller who cannot answer is a seller to skip.
- Case diameter and thickness. The watch this style copies measures roughly 42 mm across, so a listing that claims 45 mm is a different look entirely.
- Case metal. 316L stainless steel is standard. Claims of solid gold or 904L at a low price rarely hold up.
- Crystal. Sapphire with anti-reflective coating, not mineral glass.
- Movement type, beat rate, and power reserve.
- Calendar behavior at month end and at the leap year switch.
- Water resistance. Treat marketing numbers as a claim, not a guarantee.
Checks that catch a weak build
- Look at the date apertures. Uneven gaps or a date sitting off-center show sloppy assembly.
- Watch a video of the month rollover. Photos hide a frozen calendar.
- Check the moon phase disc against a known lunar date.
- Inspect hand finishes and screw slots. Polished bevels and blued screws separate tiers.
- Confirm the rotor and engraving match the photos you were sent.
Red flags in listings
Stock renders with no live photos, prices far below the market for the claimed movement tier, "Swiss made" markings on inexpensive builds, and pressure to pay outside a protected method. Any one of those is reason enough to walk away. Keep in mind that buying or importing counterfeit goods carries legal risk in the United States, and resale is not a realistic option.
How to compare two 725.038 listings
Put the same seven questions to both sellers: movement tier, calendar function, case size, case material, crystal, warranty, and spare parts. The listing with clear answers and a live video of the calendar changing is the better buy, even when it costs more. The catalog code is shared. The build quality is not.
FAQ
Is 725.038 an official Lange reference?
No. It behaves like a seller catalog code. Official brand references follow a different numbering pattern and appear in the maker's own documentation.
Does the perpetual calendar work on a replica?
On premium builds, yes, at least for the month length corrections. On budget tiers the subdials are decorative. Always request a demonstration video.
What should I check first on delivery?
Set the calendar to a known date, verify the date snaps at midnight, then check the moon phase against the current lunar day. Anything that fails in the first hour usually fails for good.
