The fake Audemars Piguet Royal Oak Offshore 26401 is a replica of the 44mm chronograph. A high-quality replica should match the genuine dimensions, dial layout, and finishing. To evaluate one, focus on case thickness, dial text, date wheel, and movement decoration.
Prerequisites
Gather reference photos of the genuine 26401 and a digital caliper. A jeweler's loupe helps inspect small details.
How to Evaluate a Fake AP Royal Oak Offshore 26401
- Measure the case diameter and thickness. The genuine 26401 is 44mm wide and about 14.4mm thick. Use calipers. Replicas often are 1-2mm thicker.
- Inspect the dial. Check the "Audemars Piguet" logo and "Royal Oak Offshore" text. The font should be crisp and correctly spaced. The tapisserie pattern should have sharp squares.
- Examine the subdials. The 26401 has three subdials at 12, 6, and 9 o'clock. The spacing and size must match the genuine. The hands should be the correct shape.
- Check the date window and cyclops. The date should be centered and the cyclops magnification should be 2.5x. Replicas often have a distorted cyclops or wrong date font.
- Look at the bezel screws. The eight hexagonal screws should be aligned so the slots point toward the center. On replicas, they may be random.
- Study the caseback and movement. The genuine has a sapphire caseback showing the caliber 3126/3840. A replica may have a decorated movement or a solid caseback. Look for engraving quality.
- Test the chronograph functions. The pushers should have a smooth, firm action. The chronograph should start, stop, and reset precisely.
- Feel the weight and balance. The genuine weighs about 160g with a rubber strap. A replica may feel lighter or heavier.
Common Flaws to Avoid
- Thick case and wrong caseback.
- Misaligned date wheel.
- Poorly printed dial text.
- Screws not aligned.
- Cheap strap or clasp.
