A Natural-Stone Dial That Makes Every Example Singular

There is color, and then there is geological color.

This 38mm Audemars Piguet CODE 11.59 places a natural turquoise stone dial inside an 18K white-gold case, letting the irregular dark matrix of the mineral become part of the watch’s identity. No printed approximation can reproduce that effect. The pattern exists because the stone exists.

Released in 2026 and initially introduced in Japan ahead of its wider international release, reference 77410BC.OO.A351KB.01 is one of the more expressive recent interpretations of the CODE 11.59 collection. Audemars Piguet itself describes the reference as pairing an 18-carat white-gold case with a turquoise stone dial, while contemporary launch coverage confirms the natural turquoise construction and Japan-first introduction.

Description

The watch begins with a 38mm 18K white-gold case, a size that gives the CODE 11.59 architecture a particularly balanced presence.

At first glance the case appears round, but its construction is far more dimensional. The collection’s signature architecture layers a rounded bezel and caseback around a faceted central case, producing changing planes of light when viewed from different angles.

Here, the cool sheen of white gold creates the ideal frame for the extraordinary dial.

The dial is fashioned from natural turquoise stone, its brilliant blue surface crossed by naturally occurring darker matrix formations. These irregular patterns are not defects or printed decoration. They are part of the mineral itself, meaning the visual fingerprint of one dial will differ from another.

That makes the watch unusually personal for a contemporary production reference.

The dial is surrounded by a matching turquoise inner bezel carrying a discreet minute scale. Slender 18K white-gold hands are treated with luminescent material, while the applied hour markers are executed in 18K pink gold with a rhodium-toned finish.

The color balance is surprisingly sophisticated.

White gold keeps the case cool and restrained. Turquoise supplies the saturated color. The rhodium-toned markers preserve visual coherence without competing with the stone.

A matching textile-textured turquoise rubber strap continues the color outward from the dial and closes with an 18K white-gold pin buckle.

A second turquoise alligator strap is also stated to accompany the watch, allowing the character to shift from contemporary sport-luxury to something more formal.

Inside is Audemars Piguet’s automatic Calibre 5909, visible through the sapphire crystal caseback.

The movement operates at 28,800 vibrations per hour, uses 29 jewels, consists of 174 components and provides approximately 60 hours of power reserve. It displays hours, minutes and central seconds.

The watch is rated to 30 meters water resistance.

Identification

The core specifications match Audemars Piguet’s official reference page and current dealer records for this exact reference.

The Turquoise Dial

The dial is the reason this watch exists.

Unlike lacquer, enamel or a colored metal surface, natural turquoise carries visual evidence of its formation. The darker veins and cloud-like matrix visible across this particular example create depth without any conventional guilloché or printed pattern.

Audemars Piguet has a long history of experimenting with unusual decorative and hard-stone dials, and this 2026 reference brings that tradition into a modern CODE 11.59 format.

The company’s release material specifically identifies it as a turquoise stone dial rather than merely a turquoise-colored dial.

That distinction matters.

Every natural stone dial possesses variation.

Collectors are therefore not merely choosing a reference. They are also choosing the specific character of the individual stone.

Case Architecture

The CODE 11.59 case rewards side-profile viewing.

Its lugs are openworked and highly architectural, creating an impression of lightness despite the precious-metal construction. The polished and brushed surfaces catch light differently, while the sapphire caseback exposes the automatic movement beneath.

At 38mm by approximately 9.6mm, this model is notably restrained compared with many contemporary luxury watches.

It has presence without requiring bulk.

The proportions also make the reference genuinely versatile across wrist sizes.

Calibre 5909

Audemars Piguet Calibre 5909 is a modern self-winding movement developed for the more compact 38mm CODE 11.59 format.

Its technical specifications include approximately 60 hours of power reserve, a 4 Hz frequency, 29 jewels, and 174 individual components.

Through the sapphire back, the movement becomes part of the visual experience rather than remaining hidden.

The architecture remains clean and contemporary, fitting the restrained three-hand purpose of the watch.

Condition

New / Unworn

The source listing classifies the watch as new.

The supplied photographs show a clean case, crystal, dial, buckle and strap presentation without visible signs of regular wear.

Natural variations, veins and darker formations visible within the turquoise dial are characteristic of the stone itself and should not be interpreted as dial damage.

Included Accessories

The source states that the watch includes the dedicated Audemars Piguet presentation case, warranty card, turquoise textile-effect rubber strap, 18K white-gold buckle and additional matching turquoise alligator strap.

The accompanying photographs also show the Audemars Piguet presentation box and documentation set.

Because the secondary strap is explicitly identified by the source and manufacturer specification as alligator, international transport of that strap may be subject to wildlife-material import or export restrictions depending on destination.

Style & Collector Position

This reference occupies an unusual place within modern Audemars Piguet.

It is neither another variation of the Royal Oak nor an anonymous dress watch.

The 38mm dimensions, white gold, stone dial and intense color create a quieter form of rarity.

There is no diamond setting demanding attention.

There is no oversized case.

The luxury comes from material, architecture and the impossible-to-repeat character of the dial.

For collectors already familiar with Royal Oak, Royal Oak Offshore and conventional CODE 11.59 references, this is a much more unusual proposition.
