A genuine Audemars Piguet Royal Oak Offshore ref. 25721ST shows three traits that copies rarely reproduce together: functional bezel screws threaded from the caseback, a Mega Tapisserie dial with sharply faceted squares, and an AP-signed automatic movement with a gold rotor. Most fakes fail on at least one of them. The fastest way to expose a 25721 fake is to compare the dial texture and the bezel screw heads at close range, then confirm the movement with a watchmaker.

Why is the reference 25721ST faked so often?
Audemars Piguet launched the Royal Oak Offshore in 1993 as reference 25721ST, a 42 mm steel chronograph that collectors nicknamed The Beast. Its size, rubber-coated crown and pushers, and eight-screw octagonal bezel made it a status symbol, and demand stayed strong for decades. Steel examples usually trade in the five figures in US dollars, which is why counterfeits of this specific reference flooded the market.

Quick check: what should you inspect first?
- Dial: raised Mega Tapisserie squares with crisp edges and even light play.
- Crown and pushers: matte black rubber coating, not bare metal or glossy plastic.
- Bezel screws: eight hexagonal heads with clean slots, seated evenly in the bezel.
- Case engraving: sharp, deep, evenly spaced lettering on the caseback.
- Movement: gold rotor, AP markings, and finishing a watchmaker can verify.
How do the bezel screws expose a fake 25721?
On the genuine watch the eight bezel screws are working fasteners, not decoration; they pass through the bezel and tighten into the caseband from below. Because each one is torqued down by hand, the slots do not sit in one machined pattern, and the heads show crisp, slightly chamfered edges. Fakes often use flat-topped cosmetic hex heads with uniform slots, soft edges, or screws that sit proud of the bezel surface.
What should the Mega Tapisserie dial look like?
Genuine Mega Tapisserie squares rise from the dial as small pyramids with sharp shoulders and a matte, granular surface. Copies stamp or print a flatter grid, so the squares look rounded, shallow, or glossy under a loupe. Check the printed text as well: the AP monogram and the Audemars Piguet lettering should stay crisp at magnification, with no bleeding or double edges.

Does the movement prove authenticity?
Inside, a real 25721 runs an Audemars Piguet automatic calibre with a gold oscillating weight engraved with brand and reference details. Fakes usually carry a decorated generic automatic or a cloned movement with a plated rotor, incorrect engraving, or rough jewel settings. The movement is the hardest part of a watch to fake well, so a watchmaker's inspection remains the decisive test.
What do box, papers, and serial numbers tell you?
Original box, certificate, and service records raise both value and confidence, and an Extract from the Archives from Audemars Piguet confirms the reference and production details tied to a specific serial number. Fakes often arrive with mismatched paperwork, blurred printing, or a serial that does not match the caseback engraving. Compare the caseback serial with the documents before you discuss price.
Can you authenticate a 25721 without opening the case?
You can rule out most fakes with a loupe, a scale, and a careful look at the finishing, but you cannot confirm a genuine movement without access to the calibre. Weigh the watch in hand: a steel 25721 should feel dense and balanced, not hollow or top-heavy. If the seller refuses an inspection by an independent watchmaker or a brand service center, treat the offer as a red flag.
