Audemars Piguet Royal Oak 15500ST Series

Product Description

The Audemars Piguet Royal Oak 15500ST is a representative 41 mm stainless steel selfwinding model from the Royal Oak collection. Introduced in 2019, it retains the distinctive design language of the Royal Oak while introducing significant updates to the dial proportions and mechanical configuration, giving this iconic luxury sports watch a more contemporary visual and technical character.

Since its debut in 1972, the Royal Oak has established a distinctive identity through its octagonal bezel, exposed hexagonal screws, integrated metal bracelet and architectural geometry. The 15500ST preserves these defining elements while combining refined metal finishing, a Grande Tapisserie dial and a new-generation selfwinding movement.

Constructed with a stainless steel case and integrated stainless steel bracelet, the 15500ST combines a strong sporting character with the sophisticated finishing associated with haute horlogerie. Different full reference numbers are available with different dial configurations, allowing the 15500ST to offer varied visual expressions while maintaining a consistent overall design identity.

Product Features

• Iconic Octagonal Royal Oak Design

The signature octagonal bezel remains one of the defining elements of the 15500ST. Eight exposed hexagonal screws and the geometrically constructed case create the strong architectural appearance immediately associated with the Royal Oak.

• 41 mm Stainless Steel Case

The 15500ST features a 41 mm stainless steel case measuring approximately 10.5 mm in thickness. These proportions provide a confident presence on the wrist while maintaining the precise and integrated character of the Royal Oak design.

• Grande Tapisserie Dial

The dial features the signature Grande Tapisserie pattern of the Royal Oak collection. Its structured three-dimensional surface produces subtle variations in appearance under changing light. Different 15500ST references are offered with different dial colors.

• Revised Dial Proportions

Compared with the preceding 15400 generation, the 15500ST features a redesigned dial layout. The applied hour markers are wider, the minute track is positioned outside the Grande Tapisserie area, and the date aperture is located further away from the center, creating a more open and balanced appearance across the 41 mm dial.

• Applied Markers and Royal Oak Hands

Applied hour markers and characteristic Royal Oak hands feature luminescent coating, preserving the recognizable aesthetic of the collection while supporting readability in lower-light conditions.

• Calibre 4302 Selfwinding Movement

The 15500ST is powered by the Audemars Piguet Calibre 4302 selfwinding mechanical movement, providing hours, minutes, central seconds and date indications. Operating at 4 Hz, or 28,800 vibrations per hour, it delivers approximately 70 hours of power reserve and represents one of the most important technical developments introduced with the 15500 generation.

• Sapphire Crystal Caseback

A sapphire crystal caseback provides a view of the architecture and operation of the Calibre 4302 selfwinding movement. The visible mechanical construction and finishing add another dimension to the overall design of the watch.

• Sophisticated Brushed and Polished Finishing

A defining element of the Royal Oak is the sophisticated treatment of its metal surfaces. Brushed and polished finishes are applied across the case, octagonal bezel and integrated bracelet, allowing different facets and edges to interact with light while emphasizing the complex geometry of the watch.

• Integrated Stainless Steel Bracelet

The stainless steel bracelet flows naturally from the case, with carefully proportioned links creating a continuous and cohesive profile. The integrated bracelet is not simply a functional component but a fundamental part of the Royal Oak design identity.

• Mechanical Performance and Everyday Functionality

The 15500ST offers water resistance to 50 metres and is equipped with a screw-locked crown. Its approximately 70-hour power reserve also provides greater convenience when the watch is rotated with other timepieces.
