A fake Audemars Piguet Royal Oak 67651 gives itself away in four places: the 33 mm case profile, the diamond-set bezel, the Grande Tapisserie dial grid, and the eight hexagonal bezel screws. The genuine reference runs on a quartz movement, so any example with a smooth-sweeping seconds hand or a rotor visible through the caseback is not authentic. Checking those four details, plus the engraved reference number on the caseback, catches most counterfeits in under a minute.
What is the Audemars Piguet Royal Oak 67651?
The 67651 is the 33 mm quartz member of the Royal Oak line, built for smaller wrists and offered mainly in stainless steel or gold, with diamond-set bezel versions in the catalog. It carries the octagonal bezel, exposed hexagonal screws, and integrated tapered bracelet that Gérald Genta drew in 1972. Power comes from Calibre 2713, a Swiss quartz movement, which helps keep the case near 7 mm thick.
How do you tell a fake Royal Oak 67651 from the real one?
Start at the caseback. Genuine examples show the reference number, case serial, and Swiss Made in shallow laser engraving with crisp edges, while counterfeits show rounded, blurry, or doubled lettering.
- Movement: Calibre 2713 is quartz. A sweeping seconds hand, a winding rotor, or exposed gears under a display back rules the watch out.
- Bezel screws: eight hexagonal screws sit in a straight line with slots angled to the same radius. Fakes use slotted screws, mismatched slot angles, or screws that stand proud of the bezel.
- Dial texture: the Grande Tapisserie grid has even squares with sharp tops and a clean stamped logo. Replicas show shallow, misaligned squares and printed text with soft edges.
- Diamonds: factory bezel stones are matched for color and clarity and set flush in a machined channel. Replacement or fake stones sit unevenly and read brighter or duller than the dial.
- Bracelet and clasp: links taper in defined steps, end links meet the case with no gap, and the AP folding clasp closes with one firm click.
Why is the 33 mm Royal Oak copied so often?
Steady demand plus a compact, simple case shape makes the reference easy to imitate from a distance. The quartz movement adds to the problem, because a battery-powered counterfeit needs no decorated rotor or hand-finished bridges to look plausible inside.
What should you verify before buying a used 67651?
Ask for the original box and papers, an Extract from the Archives from Audemars Piguet, and service records. Request angled caseback photos and confirm that the serial matches the paperwork. Any seller who refuses an independent watchmaker inspection, or who will not let the case be opened, is a pass.
Are counterfeit Royal Oak watches legal to buy or sell?
No. Counterfeit watches infringe Audemars Piguet trademarks and can be seized by US Customs and Border Protection on import. Sellers face civil damages and, in repeat cases, criminal trademark counterfeiting charges. That legal exposure sits on top of the practical loss: no resale value, no brand service, and no parts support.
Quick authentication checklist
- Confirm the movement ticks in one-second steps, as quartz should.
- Count eight hexagonal bezel screws and check slot alignment.
- Inspect the dial grid, logo print, and date window position.
- Read the caseback engraving under magnification.
- Match the serial to the AP Extract from the Archives.
