Verified by Hand
Every Audemars Piguet submitted to CrownDial passes a documented, multi-station examination. We publish what we check — because the market deserves to know.
Our Position
"Authentication is not a checkbox. It is a process — and a process only has integrity when it is visible."
Most secondary market platforms reject a meaningful portion of submissions. None tell you why, what they checked, or what a failure looks like. We do. Our process is published here in full. If a watch fails, the examiner's notes ship with the rejection. Buyers on CrownDial know exactly what was verified — not because it is a marketing claim, but because it is in the report attached to every listing.
Each submission moves through eight stations in sequence. No watch is approved until all stations pass. Any station failure pauses the process and triggers a documentation note.
The case is examined for correct AP octagonal bezel geometry (Royal Oak / Offshore) or the multi-layer architecture of the Code 11.59. We check lug-hole drilling angles, screw types and head profiles (AP uses proprietary hex-drive screws), and finishing transitions between brushed and polished surfaces. Sport references must match their original finishing specification — undisclosed polishing on a Méga Tapisserie dial surround or a satin-finished lug face is a disqualifier.
The dial is examined under loupe and raking light. AP dials have tightly controlled typography, hour-marker alignment tolerances, and lume-pad geometry. We check for signs of re-dialing (adhesive residue, alignment inconsistencies, mismatched lume aging between the dial and hands) and verify that the applied AP logo and "Audemars Piguet" text sit flush and correctly rendered.
The caseback is opened and the caliber is identified against the reference documentation. AP movements have caliber-specific rotor engravings, Geneva stripe patterns, and perlage finishing on plates. We verify the caliber matches what the reference number requires, check the rotor engraving for correct font and depth, and examine bridge finishing under a loupe for consistency with in-house standards.
End-link fit is a consistent tell. AP integrated bracelets on Royal Oak and Offshore references are machined to case-specific tolerances — aftermarket or counterfeit bracelets show gaps, asymmetric fit, or misaligned finishing lines at the lug junction. Each bracelet is removed, the end-link profile is measured, and the reinstallation fit is documented.
Crown profiles vary by reference and generation. We check crown diameter, knurling pattern depth and pitch, and the AP logo engraved on the crown face. Pushers (on Offshore chronographs) are verified for correct sealing crown type and rubber gasket integration. A replaced crown on a sport reference — even with an otherwise genuine watch — is noted explicitly.
Original papers are verified: AP warranty cards use specific paper stock, typeface, and stamping. We check that the reference and serial on the card match the case and movement. Box hardware (hinges, clasp, interior fabric) is verified against known-genuine examples. Missing papers are disclosed explicitly — they affect our grading but do not automatically disqualify a watch.
The case serial is located and recorded. We cross-reference the serial range against known AP production records to confirm it falls within the correct manufacturing window for this reference and caliber. Serials out of range for the stated reference — or mismatches between case and movement serial blocks — are automatic disqualifiers.
The watch is placed on a timing machine. We record rate accuracy (seconds per day), beat error, and amplitude across dial-up, crown-up, and pendant-down positions. Complications are cycled through their full function. Any mechanical anomaly is documented. A watch may pass authentication with a noted service recommendation — but function failures are always disclosed.
Every authenticated watch on CrownDial carries a structured examination report. It is not a summary — it is the actual station-by-station record.
