The Audemars Piguet Royal Oak Offshore is a highly coveted timepiece, particularly the references 26470ST and 15710ST. Known for their robust design and intricate craftsmanship, these watches command a significant price tag, often exceeding tens of thousands of pounds. Unfortunately, their desirability has made them a prime target for counterfeiters. The market is flooded with replicas that can deceive even seasoned collectors. Understanding the nuances of these watches is crucial for any serious buyer. This guide will walk you through the specific details that distinguish an authentic Royal Oak Offshore from a counterfeit.

The Dial Printing

The Royal Oak Offshore features a 'Méga Tapisserie' pattern on the dial, which should be perfectly aligned and consistent. The AP logo should be crisp and clear, with no bleeding or fuzziness. Check the sub-dials for precise printing and alignment. Any misalignment or smudging is a red flag.

Movement Calibre

The reference 26470ST is powered by the calibre 3126/3840, while the 15710ST features the calibre 3120. These movements are known for their intricate decoration, including Geneva stripes and perlage. A genuine movement will have a gold rotor engraved with the AP logo. Counterfeit movements often lack this level of detail and may use a generic rotor.

Caseback Engravings

The caseback of the Royal Oak Offshore should have precise engravings, including the reference number and 'Royal Oak Offshore' inscription. The screws should be perfectly aligned, and the engraving should be deep and sharp, not shallow or uneven.

Bracelet End-Links and Clasp

The bracelet of the Royal Oak Offshore should fit seamlessly into the case with no gaps. The end-links should be solid and well-finished. The clasp should have a secure, smooth action and be engraved with the AP logo. Any rough edges or loose fitment are signs of a fake.

Bezel Material and Finish

The bezel of the 26470ST and 15710ST is crafted from stainless steel, featuring a brushed finish with polished edges. The screws should be perfectly aligned in a hexagonal shape, and the finish should be flawless. Counterfeit bezels often have uneven brushing or misaligned screws.

Lume Colour and Quality

The lume on an authentic Royal Oak Offshore should glow brightly and evenly. It is typically a blue or green hue, depending on the model. Inconsistent or weak lume is a common giveaway of a counterfeit.

Weight and Sound

An authentic Royal Oak Offshore has a significant weight due to its high-quality materials. It should feel substantial on the wrist. Additionally, the sound of the movement should be smooth and consistent, without any rattling or irregular ticking.
