The Watch: The 15710ST is the Offshore Diver doing what it does best: taking the Royal Oak’s brutalist geometry and making it waterproof to 300 meters. The 42mm stainless steel case wears with presence, but the internal rotating bezel and absence of a chronograph keep things clean.
Inside is the in-houseCaliber 3120, visible through the sapphire caseback—a nice touch for a tool watch, and one that reminds you AP doesn’t do entry-level. The black Méga Tapisserie dial balances high legibility with just enough texture to keep it interesting.
Fitted with a black rubber strap and featuring a screw-down crown at 10 o’clock to operate the dive timer, the 15710ST is overbuilt in all the right ways. Not quite subtle. Definitely not trying to be.
Condition: Very good condition, recently serviced by previous owner. Some light marks, most significantly a bezel mark between 10 and 11. See photos.
