The Royal Oak Offshore Diver receives a chromatic refresh across three stainless steel references that underscore the collection's position as Le Brassus's most technically capable dive instrument. Since its 2010 debut and subsequent additions to the model, the Royal Oak Offshore Diver has distinguished itself through an internal rotating bezel operated via a dedicated crown at 10 o'clock—an unconventional solution to traditional external bezel architecture that eliminates accidental adjustment risk while maintaining ISO 6425 certification for 300-meter water resistance.
Things to Know About the Watches
The 42mm case maintains the Royal Oak Offshore Diver's established proportions with a 14.2mm thickness, and the interchangeable rubber straps via AP’s integrated system allow rapid configuration changes—each watch includes two straps, typically combining the dial’s accent color with black as an alternate option. The system integrates directly into intermediate lugs, preserving external aesthetics while enabling tool-free strap exchanges.
White gold applied hour markers, and Royal Oak hands receive a luminescent coating for visibility in low-light conditions. The date window at three o'clock features magnification for legibility, while glare-proofed sapphire crystals on both the front and the case back ensure clear views of the dial and movement.
The three new variants replace the previous khaki, grey, and blue trio with colorways that emphasize either restrained tonal integration or assertive chromatic contrast. Reference 15720ST.OO.A403CA.01 in deep teal presents the subtlest evolution, pairing a dark blue Méga Tapisserie dial with 18K pink gold applied hour markers, hands, and crown details. The black-and-white rotating inner bezel maintains legibility while the pink gold accents provide warmth against cool blue tones. This treatment mirrors the approach established with the previous khaki variant—precious metal highlights elevating stainless steel architecture.
Meanwhile, references 15720ST.OO.A010CA.01 and 15720ST.OO.A355CA.01 deliver perfect contrast through black dials accented by colored rotating inner bezels—rosy pink with a white rubber strap, and vibrant turquoise with a matching rubber. Both utilize black ceramic screw-down crowns, creating visual consistency between case and crown materials.
The Movement
Calibre 4308 powers the revised lineup, replacing the previous generation's movement. This 234-part automatic movement extends the power reserve to 60 hours while incorporating a patented setting mechanism that ensures stability and precision during function adjustment. The movement's finishing—Côtes de Genève, circular graining, and polished bevels—remains visible through sapphire casebacks alongside a blackened 22K pink gold rotor that coordinates with dial accent colors.
Summary & Price
The Offshore Diver occupies a specific position within Audemars Piguet's sports watch hierarchy: more technically capable than the 50 m Royal Oak, yet less chronograph-focused than the 100 m Offshore Chronograph. For collectors seeking genuine dive functionality from a manufacture better known for luxury sports watches than professional instruments, these three new references maintain the format's unusual combination of haute horlogerie finishing and ISO-certified dive capability.
