The Watch: The Royal Oak Offshore Diver 15703ST is peak modern AP: bold, architectural, and mechanically impressive beneath its aggressive surface. Launched in 2010, it was the first true dive watch in the Offshore family, retaining the line’s signature case architecture while adding ISO-rated 300m water resistance and an internal rotating bezel for timing dives.
The 42mm stainless steel case features a mix of brushed and polished surfaces, AP’s iconic octagonal bezel, and rubber-clad crown guards. At 10 o’clock, a secondary crown allows control of the inner dive bezel. The black Méga Tapisserie dial is pure Offshore—high-contrast, highly legible, and unmistakably AP.
Inside is the in-house Caliber 3120, a 60-hour automatic movement with a full balance bridge and 22k gold rotor.
Condition: Good condition. Marks on the crown. See photos.
