When shopping for a fake Audemars Piguet Royal Oak Offshore 26403, focus on the case profile, dial texture, and chronograph function. Replicas range from obvious fakes to detailed copies, so inspect thickness, date font, and pusher action before you commit. A reliable automatic movement matters more than a perfect logo.

What to Look For

The Royal Oak Offshore 26403 has a distinctive octagonal bezel, a textured dial, and a chronograph layout. Check these details:

  • Case: Genuine is 42mm wide and about 14.4mm thick. Replicas often add 1 to 2mm in thickness.
  • Dial: The Mega Tapisserie pattern should have crisp squares. Blurry or oversized squares are a sign of a low-grade copy.
  • Bezel screws: Eight screws should sit flush and align with the case edge. Misaligned or protruding screws are common flaws.
  • Chronograph: Pushers should start, stop, and reset with a firm click. Cheap replicas may have stiff or non-functional pushers.
  • Date window: The date font and position must match the genuine. Many fakes use a wrong font or place the window too high.

Parameter Bands

Use these ranges to judge a replica's accuracy:

  • Case diameter: 42mm (some later references vary, but 26403 is 42mm).
  • Thickness: 14mm to 15mm. Anything over 16mm looks bulky.
  • Movement: Automatic chronograph with 40 to 60 hours of power reserve. A modified ETA 7750 or a reliable clone is best.
  • Water resistance: Genuine is 100m. Replicas do not seal well, so avoid swimming.
  • Weight: Steel models should feel substantial, around 150 to 180 grams with a bracelet.

Common Pitfalls

Many buyers get burned by these issues:

  1. Seller photos: Stock images hide flaws. Ask for actual photos and a video of the chronograph working.
  2. Movement claims: Swiss made on a replica often means a cheap Chinese movement. Ask for the specific caliber.
  3. Subdial spacing: On the 26403, subdials sit at 12, 6, and 9 o'clock. Wrong spacing ruins the look.
  4. Lume: Genuine has strong lume. Fakes often have weak or uneven glow.
  5. Returns: A seller without a return policy is a red flag.

FAQ

Is the 26403 still in production? No, it is a discontinued reference, so replica quality varies by factory.

What movement should a good replica have? A reliable automatic chronograph, such as a modified 7750 or a high-quality clone.

How can I tell a high-quality replica? Look for close-up photos, a video of the chronograph, and detailed measurements from the seller.
