Answer

The Audemars Piguet Royal Oak 16202 is a 39mm extra-thin Jumbo released in 2022 for the model line's 50th anniversary. It replaced the 15202. Replica versions copy the case shape, the Petite Tapisserie dial, and the integrated bracelet. No replica uses the real caliber 7121. Most replica cases measure 8.6mm to 9.2mm thick against the real 8.1mm. Movement inside is a Miyota 9015, a Seagull ST21, or a decorated plate over one of the two.

Real 16202 specs

  • Reference 16202ST.OO.1240ST.01: steel case, blue dial
  • Case diameter 39mm, thickness 8.1mm
  • Caliber 7121, automatic, 4 Hz, 55-hour power reserve
  • Rotor in 22k gold, engraved with a 50-year mark on 2022 pieces
  • Dial: Petite Tapisserie, color named Bleu nuit nuage 50
  • Water resistance 50m

What replica makers copy

Case geometry is the hardest part to match. The 16202 has a thin bezel, eight hexagonal screws, and a case band that drops to 8.1mm. Replica cases add thickness because the movement inside is thicker than the 7121. The bracelet uses tapered links and a folding clasp. On replicas the taper is often wrong at the last three links, and the end links sit proud of the case.

Movement

A clone 7121 exists in the replica market. It carries decorative bridges, a gold-colored rotor, and engraved text. Under the plate sits a Miyota or a Seagull base. Beat rate is a check point. The real 7121 runs at 28,800 vibrations per hour. Some replica movements run at 21,600. The 16202 has a sapphire caseback, so the movement is visible.

Points to check before buying

  • Case thickness with calipers, not by eye
  • Rotor engraving and the 50-year mark on early 16202 replicas
  • Dial squares: cut into the brass, not printed flat
  • Date window position at 3 o'clock and font size
  • Hand length, the hour hand should reach the minute track
  • Bracelet taper and link count

Legal and service notes

Replicas infringe Audemars Piguet trademarks. U.S. Customs and Border Protection can seize counterfeit watches at the border, and seizures happen on single-piece shipments as well as bulk orders. Audemars Piguet will not service, authenticate, or supply parts for a replica. Resale value outside replica channels is close to zero. Replica listings price from a few hundred dollars to under $1,000. Exact figures depend on the seller and the batch.
