Fake Audemars Piguet Royal Oak Chronograph 25940: Short Answer
A fake Audemars Piguet Royal Oak Chronograph 25940 is a replica of a 42 mm Royal Oak Offshore chronograph. The genuine reference 25940 has a rubber-clad bezel, a tapisserie dial, and an AP chronograph movement. Replicas copy the silhouette. Most fail on the movement, caseback, and dial details.

What Reference 25940 Is
Audemars Piguet introduced the Royal Oak Offshore in 1993. Reference 25940 is a later Offshore chronograph. It uses a 42 mm case. It has three subdials: 30-minute counter at 12, 12-hour counter at 6, and running seconds at 9. The date sits at 3. The bezel is rubber-clad on many variants. The caseback is solid on some versions and sapphire on others. Production years and variants differ. Verify the exact reference with AP archives or auction records.

Common Fake Traits on a 25940
- Caseback engraving: fake fonts, shallow laser marks, wrong reference number spacing.
- Movement: no AP caliber, no proper chronograph module, no Geneva stripes or perlage.
- Dial: tapisserie squares too flat or too sharp; date font too thin or too bold.
- Subdials: wrong spacing, wrong hand lengths, wrong color rings.
- Bezel: rubber feels like hard plastic; texture is uneven; screws sit proud or recessed.
- Pushers: rough threads, wrong shape, no crisp click.
- Crown: wrong AP logo, weak gasket, poor winding feel.
- Case: wrong lug shape, wrong bezel screw count, wrong thickness.
- Strap: wrong stitching, wrong holes, wrong clasp engraving.
Caseback and Serial Checks
Genuine 25940 casebacks carry the reference number, serial number, and case material. The engraving is crisp. The font matches AP records. Fake casebacks often mix references, use wrong country codes, or reuse a single serial across many watches. A photo of the caseback is not enough. Compare the serial with AP service records. Ask for the original invoice and service papers. Missing papers are common on fakes.

Dial, Hands, and Date
The Royal Oak Offshore dial uses a tapisserie grid. The squares have a slight bevel. Fake dials show a flat grid or a printed pattern. The AP logo is applied on genuine dials. It has sharp edges. The date wheel font matches the period. Early 25940 dials differ from later dials. Subdial hands are thin and reach the markers. Fake hands are often too thick. Lume plots are uneven on fakes. A loop or macro photo shows these details.
Bezel, Case, and Pushers
The 25940 bezel has eight screws. The screws sit in line with the case. Fake screws are often the wrong shape. The rubber bezel insert is a key check. Genuine rubber has a matte finish and a fine grain. Fake rubber looks shiny or feels slick. The pushers are screw-down on many 25940 variants. They turn with smooth threads. Fakes have gritty threads or no threads. The crown has the AP logo. It sits flush with the case. A fake crown may be too tall or too small.
Movement
The genuine 25940 uses an AP chronograph movement. It has a modular chronograph, a central rotor, and a balance wheel. Finishing includes Geneva stripes, perlage, and polished screws. Fake movements are often quartz or a low-grade automatic. A quartz fake has a ticking seconds hand. A genuine mechanical chronograph has a smooth sweep. Some fakes use a Chinese chronograph movement with a fake rotor. A watchmaker can open the caseback. That is the only sure test.
Price and Market Signals
Genuine 25940 prices change with condition, box, and papers. A price far below market is a warning. A seller who avoids caseback photos is a warning. A seller who uses stock photos is a warning. Replica sellers use terms such as Swiss made and 1:1 to describe fakes. Those terms do not prove quality. They also do not make the watch genuine.
Legal and Ownership Notes
Counterfeit watches are illegal to sell in the United States and many other countries. Customs can seize them. Brands can pursue civil claims. A fake 25940 has no AP warranty. AP service centers will not service it. Resale value is close to zero. If you own a 25940 and need authentication, contact AP or a qualified watchmaker. Do not rely on an online photo check alone.
