Editorial
The Royal Oak Offshore Diver 15710 is AP's full dive watch interpretation of the Offshore platform: 300 meters of water resistance, a rotating inner bezel, and the same oversized 42mm presence that defines the Offshore line. It ran from 2016 to 2021, giving it a tighter production window than most AP sport references. Collectors pick it up for the combination of genuine dive utility and the Offshore's deliberately aggressive architecture.
AP produced the 15710ST.OO.A002CA.02 from 2016 to 2021 before discontinuing the reference. The case is 316L stainless steel at 42mm, fitted with a unidirectional rotating inner dive bezel rather than an external bezel , a functional choice that keeps the crown-and-case profile cleaner. Power comes from Caliber 3120, AP's in-house integrated automatic with a 60-hour power reserve and a 22k gold rotor.
The reference shipped in multiple dial configurations across the production run, with the blue dial variants drawing the most collector interest. AP has not issued a direct replacement, which has sharpened secondary-market attention on the 15710 since the discontinuation.
The inner rotating bezel is the first thing to inspect: the mechanism should click positively and the graduation printing should be sharp with no fade or lifting. Crown and pushers take more abuse on dive watches, so verify the crown screws down firmly and the gaskets have been replaced within the recommended interval. Check the sapphire crystal for chips at the edge, since the recessed inner bezel design concentrates any impact stress there.
Lug wear is common on Offshore cases that have been worn without straps, and polishing is frequently used to hide it; the brushed and polished surfaces should still show their original finishing transitions. Confirm the reference number on the caseback matches the 15710ST designation, since the Offshore Diver family has multiple references that look similar at a glance.
