Audemars Piguet in Tampa.

The Royal Oak is most of what Audemars Piguet means on the secondary market, and we keep to the references that hold their finishing under a loupe, not just across a room. The 15720ST Offshore Diver is the reference that leaves fastest whenever we have one, a rubber-clad 42 mm case with an inner rotating bezel, built for people who wanted the Royal Oak shape to say more and wear harder. The 67651ST is the other argument entirely, a 33 mm case with a diamond bezel and silver tapisserie dial, the closest the line comes to a dress watch and the one asked for by name once it has been seen on a wrist rather than a screen. Both references get the same standard before a Timekeeper will carry them to you: full set where one exists, meaning box, warranty card and any service invoices that trace to the case serial, and cases inspected under raking light before the bracelet is ever touched. On any pre-owned Audemars Piguet we check the integrated links for stretch first, since on this watch the bracelet is the case, then the octagonal bezel screws and bevels, which one careless polish erases for good and no amount of paperwork restores. If your brief is a reference we do not currently hold, tell us the model and we work the trade until an honest example surfaces.
