A replica Audemars Piguet tourbillon watch is a copy of an AP case and dial fitted with a low-cost Chinese tourbillon movement. It is not made by Audemars Piguet. Genuine AP tourbillons use in-house calibres and retail from about $150,000. Replica versions sell from $400 to $2,000. The gap shows in the movement, the case thickness, and the finishing under a loupe.

What the genuine watch is

Audemars Piguet builds tourbillons into the Royal Oak, Royal Oak Offshore, and Millenary lines. The Royal Oak Tourbillon Extra-Thin runs calibre 2924, a hand-wound movement. The cage sits at 6 o'clock under sapphire. Case width is 41 mm on most Royal Oak tourbillon references. Steel, gold, and platinum cases exist. AP finishes the bridges, bevels, and cage with hand work.

Movements inside replica AP tourbillons

Most replica AP tourbillons run one of two Chinese calibres: the Tianjin Seagull ST8000 or a Hangzhou tourbillon. The ST8000 is hand-wound, beats at 21,600 vph, and lists a power reserve near 42 hours. Its cage sits at 6 o'clock. That position limits which AP dials a factory can copy. A replica with the cage at 12 o'clock, or under a solid caseback, does not use this movement. Some sellers name ETA or AP calibres in the listing. That claim is false. No Swiss maker sells a tourbillon movement at replica price levels.

Case, dial, and finish

  • Case width: 41 mm on Royal Oak copies, 42 mm to 44 mm on Offshore copies.
  • Thickness: 10.5 mm on a genuine Royal Oak Tourbillon. Copies run 11 mm to 13 mm.
  • Metal: 316L steel, gold-plated steel, or solid gold on high-tier builds.
  • Dial: tapisserie squares differ in size and depth from the genuine grid.
  • Bezel screws: genuine screws have slots that align on one line. Copies often do not.
  • Caseback: engraving depth and font are the first tells in photos.

Price tiers

  1. $400 to $700: ST8000 movement, mineral or sapphire front, thin plating.
  2. $700 to $1,200: better case shape, sapphire front and back, AR coating on the crystal.
  3. $1,200 to $2,000: closer case thickness, hand-polished bevels, engraved rotor or bridges. The movement is still Chinese.

Service and repair

A tourbillon service needs a watchmaker who works on Chinese calibres. Many US shops decline the job. Parts are scarce. A replacement ST8000 movement costs $200 to $400. Rate and power reserve vary by unit, and sellers do not publish timing results. Buy on the assumption that the watch is not serviceable by the maker.

Legal status in the US

Import of counterfeit goods is illegal under 19 U.S.C. 1526. US Customs and Border Protection can seize and destroy a shipment. The trademark owner can file a civil claim. Orders shipped from overseas carry seizure risk, and a seizure leaves the buyer with no refund from the carrier.

Checklist before you buy

  • Get the movement name in writing, plus the factory name.
  • Ask for case width and thickness, measured with calipers.
  • Ask for photos of the movement outside the case.
  • Confirm sapphire on front and back.
  • Ask for the cage position, 6 o'clock or other.
  • Confirm the return window and who pays return shipping.
