Quick answer
A replica Lange 2 is a copy of the A. Lange & Söhne Lange 1 sold under a market shorthand. The brand has no model called Lange 2 in its catalog, so sellers use the term for the second-generation Lange 1 layout and its close variants. When you inspect one, judge five details in order: case size, dial layout, the outsize date, the movement decoration visible through the back, and the strap and clasp. Those five checks separate a convincing piece from a cheap look-alike.
What you need before you start
- A ruler or digital caliper for case and strap measurements
- A 10x loupe for dial printing and movement finishing
- Reference photos of the genuine 38.5 mm Lange 1 for side-by-side comparison
- Bright, indirect light and a phone camera for macro shots
Step-by-step evaluation
- Measure the case across the bezel and from lug tip to lug tip. The classic Lange 1 is 38.5 mm wide and about 10 mm thick, so a copy that measures 42 mm or sits above 12 mm will sit wrong on the wrist.
- Compare the dial layout against the original. The main time display sits at 9 o'clock, the outsize date at 1 o'clock, the small seconds at 4 o'clock, and the power reserve indicator at 3 o'clock. No element should crowd or touch another.
- Inspect the outsize date window with your loupe. The two date discs should meet at a crossbar with no visible gap, and the numerals should be flat, sharp, and the same height.
- Check the hands for shape and finish. Lange uses lancet hands with a clean taper, so a blunt tip or a printed white outline instead of polished metal is a warning sign.
- Turn the watch over and study the movement. The three-quarter plate should show Glashütte ribbing with straight, uniform bands, and the balance cock should carry an engraved pattern instead of shallow laser lines.
- Wind the crown with steady pressure and count the turns. A hand-wound Lange 1 runs about 72 hours, so the power reserve gauge should climb in step with each rotation.
- Set the time and date, wait an hour, then check the alignment again. Calendar discs that drift or a subdial that loses its center point point to a loose train or a dial that is not seated properly.
- Run a finger along the case flanks. Good cases alternate polished and brushed surfaces with a crisp transition, while low-grade cases feel uniform and rounded.
- Examine the strap and clasp. Look for even stitching, a real alligator grain, and a clasp with engraving and a latch that closes with a firm click.
- Ask the seller for the reference number, movement details, and return terms before you pay, then keep that message. The record matters if the watch arrives with a defect.
Red flags
- Date numerals printed on one flat disc instead of two separate wheels
- A rotor visible through the back on a model that should be hand wound
- Dial text with the wrong font weight or letter spacing
- Subdials that sit too close to the case edge or overlap the date window
- Screws painted blue rather than heat-blued metal
- A crown that feels gritty or does not spring back when you release it
Living with a replica Lange 2
Most copies run on a modified Asian or Swiss movement, so expect a daily rate somewhere between plus 10 and minus 20 seconds. Wind the watch at the same hour each day and let it rest face up overnight to keep the rate stable. Keep it away from water, steam, and strong magnets, since case gaskets on replicas are rarely rated for swimming. Have the movement cleaned and lubricated every three to five years, and store the watch in a dry box or on a soft pad so the alligator strap keeps its shape. If you plan to sell later, keep the box, papers, and any spare links together.
