Start with the Reference Number
One of the first steps in authenticating an Audemars Piguet watch is identifying the reference number. This number provides essential information about the model, case material, movement, complications and period of production. Audemars Piguet has produced numerous Royal Oak, Royal Oak Offshore and Royal Oak Concept references over the decades, often with subtle variations that can be difficult for non-specialists to distinguish.
The reference number should correspond precisely with the watch's physical characteristics. Case material, dial configuration, bracelet design, movement and clasp should all be consistent with the reference in question. For example, certain dial colours, handsets or bracelet styles may only have been available for a limited production period or on specific references. Any discrepancy should be investigated further.
Particular attention should be paid to watches that have undergone restoration or repair. While replacement components fitted during authorised servicing are not necessarily problematic, collectors generally expect these to be appropriate to the model and period. A later service dial, replacement bezel or incorrect bracelet can affect both collectability and value.
Specialists are also alert to so-called "Frankenwatches" — watches assembled from parts taken from multiple examples. These may contain genuine Audemars Piguet components but do not represent an original factory-produced watch. In the case of highly sought-after models such as the Royal Oak, the combination of parts from different references can be difficult to detect without detailed knowledge of production variations, movement numbers and case characteristics.
Establishing that the reference, serial number and component configuration are consistent is therefore one of the most important stages in the authentication process, providing the foundation for further examination of the watch.
Examine the Dial
Audemars Piguet is renowned for its meticulous dial work. The brand's famous Royal Oak models feature the distinctive Tapisserie pattern, produced using specialised machinery and finished to an exceptionally high standard.
Signs to look for include:
- Crisp, evenly printed text
- Correct logo placement and proportions
- Consistent luminous material on hands and markers
- High-quality finishing visible under magnification
- Absence of spelling mistakes or irregular spacing
Even minor imperfections can be warning signs, as Audemars Piguet's quality control standards are exceptionally high.
