The replica Lange 2 Perpetual 725.038 copies the pink gold A. Lange & Söhne perpetual calendar, and the blunt answer is that almost none of them contain a true perpetual calendar. Most versions reproduce the dial layout, the outsize date, and the moon phase window, while the calendar underneath runs on a standard 31 day date wheel or a quartz module. Buy the watch for the look, and only after you confirm which functions actually move.

What this reference is known for

The genuine watch is a pink gold perpetual calendar with an outsize date, a moon phase display, and a day and night indicator. Its identity sits in the dial: an off center main time dial, a smaller subdial for the calendar readout, and the double date window in the upper right. A replica worth buying gets that geometry right. A replica worth avoiding stretches the case, shrinks the subdial, or prints a date font that reads thin and flat.

Prerequisites

  • Know your wrist size in millimeters and compare it to the stated case width, not the lug to lug guess in a listing photo.
  • Decide in advance whether you want working calendar functions or a look only piece, because those are two different purchases.
  • Confirm the seller accepts returns and states which payment method protects you.
  • Check what your country charges on imported watch shipments and who pays a seizure.

Inspection steps

  1. Compare the listing photos against the official reference images and confirm the subdial positions, date window placement, and hand shapes match the 725.038 layout.
  2. Request a live video, not a photo set, so you can see the second hand sweep and hear the movement.
  3. Ask the seller to advance the date on camera and watch whether the outsize date jumps instantly or drags across the window.
  4. Ask for a close shot of the moon phase disc and count the stars and moon position for alignment outside the printed window.
  5. Measure the case with calipers in the video and compare the number to the specification quoted.
  6. Ask which movement is inside and whether it is a decorated automatic, a quartz module, or a hand wound copy.
  7. Weigh the watch on camera, since a case that feels light usually means plated brass rather than stainless steel.
  8. Inspect the strap, lugs, and clasp for sharp edges, uneven stitching, or a logo etched off center.
  9. Wind the watch and set it down for 24 hours to verify the stated power reserve.
  10. Treat any water resistance claim as decoration and keep the watch away from water.

Red flags

  • Stock photos only, with no real image of the actual unit.
  • A promise of a fully functional perpetual calendar at a low price, since the module alone costs more than the whole watch.
  • No stated factory or movement name.
  • Refusal to show the caseback or the date change on video.

Ownership notes

Expect the calendar to be a month wheel rather than a perpetual mechanism, so plan to reset it after short months. Keep the crown pushed in, store the watch away from magnets, and have a local bench look at the movement if it starts losing minutes a day. Servicing a copy is often cheaper than replacing it, but only if the movement is a common automatic calibre that a general watchmaker can source parts for.
