Audemars Piguet Royal Oak Offshore Diver Steel — Turquoise Index Dial | Ref. 15710ST.OO.A032CA.01

The Royal Oak Offshore Diver stands as one of the most technically committed expressions of the Offshore bloodline — a certified diver's instrument wrapped in the unmistakable octagonal architecture that Emmanuel Gueit extrapolated from Genta's original vision in 1993. Reference 15710ST.OO.A032CA.01 pairs the 42 mm stainless steel case with a vivid turquoise dial that immediately recalls the tropical waters this watch was engineered to explore, making it among the most optically arresting configurations in the Offshore Diver canon.

Inside, Calibre 3120 provides the automatic propulsion — a manufacture movement boasting a 60-hour power reserve and a 21,600 vph frequency, with 40 jewels and a variable-inertia balance wheel for enhanced regulation stability. The steel domed bezel carries a unidirectional dive scale, while the caseback and screw-down crown seal the case to professional dive standards. Index hour markers stand proud of the turquoise surface, and the integrated rubber strap, secured via a tang buckle, pairs athletic function with understated comfort.

Produced during the 2014–2021 production window, this reference was available in a palette of bold dial colours that have since become genuinely sought-after on the secondary market — turquoise in particular commanding strong collector premiums. With box and papers accompanying the watch, the 15710ST in turquoise presents as both an authentic aquatic tool and a masterclass in sporting luxury. A compelling proposition for the collector who demands performance credentials alongside undeniable visual presence.
