Fake Audemars Piguet Code 11.59 chronographs use reference numbers that copy the genuine line. They also carry short factory codes assigned by replica makers. The genuine reference numbers start with 26393. Replica factory codes include APS, OMF, and ZF. The main tells are the movement, date position, dial printing, and caseback engraving.

Replica Factory Codes

Replica makers assign short codes to their versions. For the Code 11.59 chrono, these codes appear in dealer listings and on plastic tags. Common codes:

  • APS: Uses a clone 4401 movement. This is the highest tier.
  • OMF: Uses a modified 7750 movement with a date overlay.
  • ZF: Uses a decorated 7750 movement. Lower price.
  • BP: Uses a 7750 movement with a closed caseback.

These codes change. Factories update versions without notice.

Movement Differences

The genuine calibre 4401 is an in-house integrated chronograph. It has a column wheel and vertical clutch. It beats at 28,800 vph. Power reserve is 70 hours. Replica movements:

  • Asian 7750: 28,800 vph, 42-48 hours power reserve. The rotor often has shallow engraving.
  • Clone 4401: 28,800 vph, 60-70 hours power reserve. Better finish. Found in APS watches.

Check the rotor engraving. Genuine has deep, crisp lettering. Replica rotors are often lighter.
