Appearance design: a perfect fusion of classic and innovation

The Royal Oak Offshore Diver Ref. 15720ST.OO.A009CA.01 features a stainless steel case with an anti-glare treated sapphire crystal and caseback for enhanced clarity and scratch resistance. The grey ceramic screw-down crown is both sleek and user-friendly, demonstrating the brand’s meticulous attention to detail.

The watch measures 42mm and is 14.2mm thick, creating a commanding presence on the wrist. Its 300m water resistance makes it a reliable companion for diving enthusiasts, whether for daily use or deep-sea adventures.

The dial design is particularly striking. The grey dial is engraved with the “Méga Tapisserie” pattern, and features luminescent white gold applied hour markers and Royal Oak hands, making it easy to read even in dim conditions. The blue rotating inner dive timer bezel and white 60- to 15-minute scale add visual depth and facilitate the user’s dive time measurement.

In terms of strap, it is equipped with a gray easy-to-change rubber strap and a stainless steel pin buckle. It is comfortable and easy to replace, and can easily adapt to the needs of different occasions.

4308 automatic movement: the heart of powerful performance

The Royal Oak Offshore Diver Ref. 15720ST.OO.A009CA.01 is equipped with the new 4308 automatic caliber, guaranteeing its powerful performance. This caliber is rich in functions, enabling diving time measurement, hours, minutes, central seconds, and date display, meeting both daily and professional needs.

The 4308 movement contains 32 rubies, effectively reducing friction and enhancing the stability and durability of the movement. Its automatic winding design eliminates the need for manual winding, making it convenient and practical. With a guaranteed minimum power reserve of 60 hours, the watch maintains accurate time even when not worn for short periods.

The movement has a total diameter of 32 mm and comprises 234 components, each meticulously polished and assembled. The balance wheel beats at a frequency of 4 Hz (28,800 vibrations per hour) and is only 5.2 mm thick, ensuring both performance and a slim design.
