A "fake Audemars Piguet Royal Oak 16402" is not a copy of a real watch, because Audemars Piguet has never catalogued a Royal Oak with the reference 16402. The number circulates in replica listings and search queries for the Royal Oak Jumbo Extra-Thin, and the closest genuine references are 16202ST and the earlier 15202ST. Any listing that advertises a 16402 is either mislabelled or inventing a reference.
Does Audemars Piguet make a Royal Oak 16402?
No. Audemars Piguet reference numbers for the Royal Oak run through families such as 5402, 15202, 15500, 15510 and 16202. A 16402 does not appear in the brand catalogue, in auction archives, or in authorised dealer inventory.
Reference accuracy is everything in the Royal Oak market, so a wrong number is a red flag on its own. It usually signals a listing copied from a template, a mistyped model, or a seller who never handled the watch.
Which real Royal Oak references get sold as "16402"?
The 16202ST is the reference most often disguised behind "16402". It arrived in 2022 for the Royal Oak's 50th anniversary and replaced the 15202ST as the Jumbo Extra-Thin.
- Case size: 39 mm, only 8.1 mm thick
- Movement: Calibre 7121, 50-hour power reserve, 22k gold rotor
- Dial: Grande Tapisserie with date at 3 o'clock and no seconds hand
- Material: steel (ST), plus gold, platinum and titanium variants
Older 15202ST models share the same 39 mm and 8.1 mm profile but use Calibre 2121 instead. Both sit near the top of the most counterfeited watch list worldwide.
How can you tell a fake Royal Oak 16202 from the real thing?
Case thickness and finishing
8.1 mm is brutally hard to fake. Most replicas measure 9 mm to 10.5 mm thick, and the extra millimetre shows at the lugs and the caseback rim. Genuine bevels catch light as one continuous polished line running from bezel to bracelet.
Dial and tapisserie pattern
Grande Tapisserie squares on a genuine dial are deep, evenly pitched and stamped to a fixed grid across a matte field. Replica dials often look shallow, waxy or slightly misaligned near the date window. The date disc should be white with crisp black numerals, not off-white or oversized.
Movement and caseback
A real 16202ST has a sapphire caseback showing Calibre 7121, its 22k gold rotor and engraved bridges. Replicas typically hide a Miyota, ETA or Chinese automatic behind a decorated cover plate. Engraved reference and serial numbers on the caseback should be sharp, correctly spaced and consistent with the paperwork.
Bracelet construction
Genuine Royal Oak bracelets use screws with polished heads and link edges that are chamfered on both sides. Replica bracelets often accept only one screwdriver size, have sharp inner edges, and flex with a slight rattle.
What separates replica Royal Oak tiers?
Replica Royal Oaks are sold in loose quality tiers, and the price gap reflects the case, dial and movement rather than the badge. Entry tiers use mineral glass, printed dials and basic automatic movements. Higher tiers chase 1:1 external dimensions, sapphire crystal and cloned or modified movements.
Even the strongest replicas fail on thickness, bracelet feel and movement decoration under a loupe.
What should you check before buying any Royal Oak?
- Verify the reference number against the manufacturer's own catalogue.
- Ask for caliper measurements of case thickness, not photos alone.
- Request movement photos through the caseback plus a serial number check.
- Compare finishing under angled light, especially bezel bevels and bracelet chamfers.
- Confirm a return window and pay with a method that allows a dispute.
Is a "16402" replica legal to buy or sell?
In the United States, selling a counterfeit watch as genuine is trademark counterfeiting and carries criminal penalties. U.S. Customs and Border Protection can seize counterfeit shipments at the border. Genuine Audemars Piguet designs and marks are protected by trademarks that replicas inherently infringe.

Replica pricing spans roughly $200 to $900 depending on tier, while a genuine steel 16202ST trades well above retail. Price alone does not prove quality.
