Short answer
"104.032" is a listing code used by replica sellers. It is not a reference number in A. Lange & Söhne's published Zeitwerk catalog. Catalogued Zeitwerk references sit in the 140.xxx and 148.xxx ranges. The watch behind the code copies the Zeitwerk, a Lange model released in 2009 with jumping hour and minute windows instead of hands.
What the genuine Zeitwerk is
- Case: 41.9 mm across, 12.6 mm thick, in pink gold, white gold, platinum, or steel.
- Display: two apertures. The minute disc snaps once per minute. The hour disc snaps at the top of the hour.
- Movement: hand-wound L043.1 family, 388 parts, 68 jewels, 18,000 vph, about 36 hours of power reserve.
- Escapement: constant-force, patented in 2009. It feeds a fixed energy amount to the balance each second.
- Seconds: small subdial at 6 o'clock. The power reserve display sits on the movement side.
Why the code appears on replica sites
Sellers reuse Lange-style six digit codes because buyers search by number. "104.032" maps to no case metal, dial color, or production year in any Lange catalog. Treat it as a shop SKU. Two sellers can use the same code for two different watches.
How the copies are built
Mass-market copies of the Zeitwerk use quartz or a low-cost automatic base. The jumping display is the hard part, so most copies print the digits on a disc that rotates over 60 seconds instead of snapping. Some mid-range copies, priced from $250 to $600, add a modified automatic with a jump lever. None carry a constant-force escapement. Case thickness on copies runs 14 mm to 16 mm. The original is 12.6 mm.
Checks that separate the two
- Watch the minute disc at a minute boundary. Genuine: instant snap. Copy: sweep or slow roll.
- Measure thickness with calipers. Genuine Zeitwerk: 12.6 mm.
- Look at the seconds subdial. On copies it often runs off a separate module with no link to the jump train.
- Read the caseback. Genuine examples show a hand-engraved balance cock and a German silver three-quarter plate.
- Check the weight. Platinum and gold originals run heavy. Base-metal copies do not.
Price and market
Genuine Zeitwerk examples trade from $60,000 to $200,000 on the secondary market, based on metal and condition. Replica listings sit between $80 and $700. Service on a genuine Zeitwerk at Lange runs into four figures. The brand services no copy.
