If you are shopping for a replica Audemars Piguet Code 11.59 and a listing shows a string such as codes 11 45100, treat that number as a seller tag, not a factory grade. The watch you are actually comparing is the Code 11.59 by Audemars Piguet: a round case with an octagonal midcase, a domed sapphire crystal, and a lacquered dial with applied numerals. Buy the version that matches the genuine reference size and movement layout first, then judge the finish. Ask the seller to map any listing code back to a real AP reference so you can compare specs side by side.

Start With the Genuine Reference, Not the Listing Code

Audemars Piguet launched the Code 11.59 in 2019. The main references split into selfwinding, chronograph, and complicated models. The selfwinding 41mm case measures 10.7mm thick and runs calibre 4302 with a 70-hour power reserve. The chronograph 41mm case measures 12.6mm thick and runs calibre 4401 with a column wheel and flyback. A listing code such as 45100 does not tell you which of those you are buying. It might be an internal SKU, a batch number, or a typo. Before you pay, confirm the genuine reference the replica copies, then check the case diameter, thickness, and movement type against that reference.

What to Look For

Case and Crystal

  • Octagonal midcase between a round bezel and a round caseback. The shape should be crisp, with sharp brushing on the sides and polish on the bevels.
  • Lugs that flow from the bezel. On the genuine watch the lugs are soldered to the bezel, so a visible seam or a gap is a warning sign.
  • Domed sapphire crystal with anti-reflective coating on both sides. Flat mineral glass and a strong blue tint are common on low-grade builds.
  • Case thickness within about 0.5mm of the genuine figure. A thick case often hides a low-grade movement or a spacer.

Dial and Hands

  • Lacquered dial with a deep, even finish. Faded or patchy lacquer is easy to spot in daylight.
  • Applied numerals and hands with clean edges. Printed numerals on a Code 11.59 dial look flat and wrong.
  • Correct date window position and font. If the date sits in the wrong spot, the movement is not the right layout.
  • Lume that is white in daylight. Green or blue lume on a modern Code 11.59 is a mismatch.

Movement

  • Beat rate of 28,800 vibrations per hour, which is a smooth sweep at 4Hz.
  • Power reserve close to 70 hours on the selfwinding clone. Test it overnight before you trust it.
  • Chronograph with a column wheel and a crisp reset. A gritty pusher or a jumping seconds hand points to a modular movement.
  • Correct date change direction and a clean flip at midnight.

Parameter Bands to Compare

  • Case diameter: 41mm for most references, with a smaller 38mm option on some versions.
  • Case thickness: 10.7mm selfwinding, 12.6mm chronograph.
  • Movement frequency: 4Hz, or 28,800 vph.
  • Power reserve: about 70 hours on the calibre 4302 and 4401 families.
  • Crystal: domed sapphire, double anti-reflective coating.
  • Water resistance: the genuine watch is not a dive model, so treat any replica rating as optimistic and keep it away from water.

Common Pitfalls

  1. Buying from a listing code alone. A code like 45100 tells you nothing about the factory, the movement, or the reference.
  2. Trusting stock photos. Ask for timestamped photos and a short video of the watch running.
  3. Ignoring thickness. A 13mm or 14mm case on a watch that should be 10.7mm is a clear tell.
  4. Accepting a quartz chronograph. The genuine Code 11.59 chronograph is mechanical with a sweep seconds hand.
  5. Paying a premium for a Swiss made label without movement details. Ask for the movement name and the factory name in writing.

FAQ

What does codes 11 45100 mean in a listing?

That string is a seller tag or a garbled version of Code 11.59. Ask the seller to name the genuine Audemars Piguet reference and the factory that built the watch. If the seller cannot answer, move on.

Which factory makes the best replica AP Code 11.59?

Factory rankings change with each batch. Compare recent buyer photos, movement specs, and case thickness instead of trusting a single brand name.

Can I swim with a replica Code 11.59?

No. The genuine watch has limited water resistance, and a replica seal is not tested to the same standard. Keep it dry.

How do I check the movement before buying?

Request a video that shows the seconds hand sweep, the date flip, and the chronograph start, stop, and reset. A smooth sweep and a clean reset are the two simplest checks.
