A replica of the Lange 405.031 costs about $280 to $2,400. Most listings sit between $450 and $900. Three parts set the price: the movement, the case finish, and the dial printing. Sellers under $300 ship a quartz unit or a low-grade automatic. Sellers above $1,500 claim a clone movement and decorated bridges. Ask for photos of the caseback before you compare quotes.
What reference 405.031 is
Reference 405.031 sits in the Datograph Up/Down series, the 405.xxx block of A. Lange & Söhne chronographs. The watch carries a flyback chronograph, a large date, and a power reserve display. Case metal for the 405.xxx run is rose gold or platinum. Confirm the metal and dial color in the listing text. Replica sellers reuse the same reference number across different descriptions, so the number alone does not tell you which copy you are buying.
Replica price tiers
- Under $300. Quartz movement. Printed date. Flat plate bridges. The date jumps once at midnight instead of in two steps.
- $300 to $600. Chinese automatic chronograph movement. Mineral glass on most units. Sapphire on a few.
- $600 to $1,200. Modified or clone chronograph movement. Applied numerals. Cleaner edge finishing on the bridges.
- $1,200 to $2,500. Claimed 1:1 copy. Decorated movement. Engraved caseback. Demand a video of the chronograph start, stop, and reset.
What the price does not fix
No replica of this reference matches the genuine movement layout. The genuine watch runs a Lange manufacture calibre with a column wheel and a horizontal clutch. A $900 copy runs a modular chronograph with a cam or a vertical clutch. Pusher feel differs. Date font differs. Weight differs, because a rose gold case and a steel case do not balance the same on the wrist. Custom engraving and box sets add cost and add nothing to accuracy.
Genuine price for context
Secondary market asking prices for the genuine 405.031 run $60,000 to $110,000. Results move with the case metal and with box and papers. That gap explains the market and explains why quality claims get inflated at resale.
