Short answer
"Fake Lange 2 Perpetual 725.038" is a search phrase used by replica sellers. A. Lange & Söhne does not list a Lange 2 model. The German maker's perpetual calendar watches are the Lange 1 Perpetual Calendar and the Datograph Perpetual. The digits 725.038 do not match a published reference for a Lange 2, so the number works as a seller code, not a factory reference. Buyers who search that string want a copy of a Lange perpetual calendar with an outsize date, a month display and a moon phase.
What the genuine watch looks like
The Lange 1 Perpetual Calendar arrived in 2021. Case size is 41.9 mm in pink gold and white gold versions, per A. Lange & Söhne and launch coverage. The dial carries an outsize date, a retrograde month ring, a moon phase, a day and night indicator, and small seconds. Caliber L021.3 is self-winding with a 50-hour power reserve. Retail price sat above $100,000 in precious metal.
What replica versions copy
- Case: 41 to 42 mm steel, sometimes gold plated; thickness often 12 to 14 mm against the genuine profile.
- Crystal: sapphire on higher tiers, mineral glass on cheaper builds.
- Movement: Chinese automatic, often a Seagull or Hangzhou base, with a decorated rotor plate stamped with an engraving in the Lange style.
- Dial: printed month track, glued markers, painted moon disc.
- Strap: leather with a tang buckle or a signed deployant clasp copy.
Where copies stop matching
A real perpetual calendar tracks leap years to 2100 without correction. Replica modules show a month hand and a date, then need manual setting after a short power loss. The outsize date on the genuine watch jumps in one instant; copies roll over across several hours. Hand-engraved balance cocks, screwed gold chatons and striped bridges do not appear on replica movements.
Checking a listing
- Ask for a case back photo. Genuine L021.3 has a hand-engraved balance cock.
- Ask for a video of the date change at midnight.
- Measure the case. Published genuine size is 41.9 mm.
- Compare the month ring font against the maker's catalog image.
