Short answer

Most replica Audemars Piguet complications are chronograph and moonphase builds that use mass-produced movement bases. They can keep time and run the chronograph, but subdial spacing, case thickness, and pusher feel differ from the genuine piece. True perpetual calendars, minute repeaters, and grande complications do not exist in the replica market in any functional sense. What is sold under those names is either a simplified calendar module or a decorative opening that looks like a tourbillon.

Prerequisites

  • A reference number for the genuine model you want to compare against.
  • Basic vocabulary: chronograph, moonphase, perpetual calendar, tourbillon, minute repeater.
  • Awareness that selling or importing counterfeit watches is illegal in the United States and that customs officers seize such shipments.

What counts as a complication on an AP

Audemars Piguet builds its reputation on complications. The Royal Oak Offshore carries chronographs, the Royal Oak Selfwinding Perpetual Calendar adds a full calendar that accounts for leap years, and the Code 11.59 line includes the Universelle, a watch with more than 40 functions. Replica makers copy the visible result of these watches, not the engineering behind them.

How replica complications are built

Chronographs

Nearly all replica AP chronographs use the Asian 7750 or a derivative. This movement is a copy of a proven Swiss design, so it starts, stops, and resets. The trade-off is height: the module adds roughly 1.5 to 2 mm to the case. A genuine Royal Oak Offshore chronograph sits at about 14.4 mm, and many replicas measure closer to 16 mm or more. Subdial positions also drift, which shows up when you compare photos side by side.

Moonphase and calendar modules

Two different things get sold as a moonphase. The first is a real 29.5-day moon disc driven by a gear train. The second, far more common, is a 24-hour day and night disc with a printed moon. Both look similar in a photo. The day and night version does not track the lunar cycle, and it will be wrong within a week of a full moon.

Tourbillons

A genuine tourbillon puts the balance and escapement in a rotating cage that turns once per minute. Replica versions fall into two groups. Some use a real, inexpensive Chinese tourbillon carriage. Others use an open heart cutout with a moving decorative bridge. Check the rotation speed and whether the balance wheel itself travels around the dial center.

Minute repeaters and grande complications

These do not exist as functional replicas. A minute repeater requires racks, snails, and hammers tuned by hand, and the tooling cost exceeds what the replica market can absorb. Any listing that advertises a chiming replica AP is describing cosmetic gongs or a sound file in a marketing video.

Complications replicas handle well

  1. Time and date: standard, reliable, and cheap to replace.
  2. Chronograph: functional with a working reset, though the pusher feel is soft.
  3. 24-hour day and night indicator: simple and durable.
  4. Open heart and skeleton dials: visually close to the genuine layout.

Complications replicas handle poorly

  1. Perpetual calendar: most replicas skip leap year logic and need manual correction every March 1.
  2. True moonphase: rare, and the printed disc version is far more common.
  3. Flying tourbillon: the cage often rotates at the wrong rate or is decorative only.
  4. Minute repeater: not available as a working mechanism.
  5. Split seconds and rattrapante: no functional replica exists.

How to evaluate one in person

  1. Measure case thickness with calipers and compare it to the published figure for the reference.
  2. Photograph the dial straight on, then overlay it against a genuine photo to check subdial spacing and date window position.
  3. Run the chronograph for 60 seconds, stop it, and reset. The hands should snap back to zero together.
  4. Watch the moonphase for three nights. A real lunar disc moves a small amount each night; a day and night disc moves half a turn.
  5. Count the tourbillon rotations against a stopwatch. One full turn should take 60 seconds.
  6. Set a full calendar watch to February 28 and advance the date to see how it handles the month end.
  7. Check the winding feel and the crown threads. Rough threads and grinding winding are common on low grade cases.

Cost, repair, and legal reality

Clone movement parts are not stocked by watchmakers, and many repair shops refuse the work outright. A failed chronograph module often means replacing the whole movement rather than servicing it. Water resistance claims on replica cases are unverified, so keep them away from pools and showers regardless of what the listing says. On the legal side, U.S. Customs and Border Protection seizes counterfeit shipments, and trademark law allows civil penalties against sellers. Resale value is effectively zero because no authorized dealer or auction house will touch the watch.

FAQ

Is a replica AP perpetual calendar accurate?

No. It is generally a complete calendar that needs correction at the end of February and does not track leap years.

Can a replica tourbillon be serviced?

Rarely. Parts come from the same low volume supply chain that built the watch, and most independent watchmakers will decline the job.

Do replica complications hold value?

No. There is no secondary market for counterfeit watches through legitimate channels.
