The entry point of the Code 11.59 collection and the reference that defines its visual vocabulary. The 15210 launched in 2019 in white gold and pink gold, with a three-part dial construction unique to the collection: an outer chapter ring, an inner dial, and a central plate, each finished separately and assembled to create the characteristic depth and dimensionality. The inaugural dial colors — royal blue, smoked black, white, tapisserie brown — established a palette that has expanded considerably. In 2023, AP introduced the first steel Code 11.59 (15210ST), a landmark moment for the collection's accessibility and market reach. The steel reference came alongside new dial executions including the celebrated Bolshoi Grand Feu enamel dial edition. Diamond-set and two-tone configurations (white gold/pink gold and ceramic combinations) round out the 15210 family. In 2023, a 38mm pink gold selfwinding (ref. 77410OR, powered by the slim Cal. 5900 at just 3.9mm thick with 60h power reserve) extended the line to a smaller case diameter.

The 26393 houses the Cal. 4401, Audemars Piguet's first integrated selfwinding chronograph movement — an instrument of considerable historic significance. Unlike the modular chronographs AP had used for decades, the 4401 was designed from ground up as a single unified architecture, with a column wheel regulating the chronograph function, a vertical clutch providing smooth engagement, and a flyback mechanism resetting the seconds hand to zero with a single push rather than requiring two separate operations. The 4401 delivers 70 hours of power reserve and was subsequently adopted into the Royal Oak and Royal Oak Offshore, validating its architecture at the highest level. The first generation of 26393 references launched in white and pink gold; 2023 brought the steel configuration (26393ST) and the visually arresting blue ceramic/white gold combination. All configurations of the 26393 chronograph are actively purchased.

The Code 11.59 Flying Tourbillon family spans two case sizes and two architectures. The 41mm Flying Tourbillon (ref. 26396, Cal. 2950, 65h power reserve) uses a central automatic rotor with the flying tourbillon at 6 o'clock; the blue aventurine white gold reference is the most collected configuration. The Selfwinding Flying Tourbillon Openworked (ref. 26600, Cal. 2948, hand-wound, 80h) reveals the skeletonized movement architecture at full depth. In 2025, the 38mm case received the ultra-thin Cal. 2968 (also known as RD#3, first introduced in 2022 on Royal Oak models) — just 3.4mm thick with a 50h power reserve and peripheral drive escapement. The four 38mm references (ref. 26665) include three stone-dial limited editions of 150 pieces each for the 150th anniversary: ruby root from Tanzania in white gold (26665BC), sodalite from Brazil in pink gold (26665OR), and malachite from Zambia in yellow gold (26665BA). A fourth 38mm version in sand gold set with 235 diamonds (26665SG) completes the 38mm family. All Flying Tourbillon configurations are actively purchased.

The 26399 combines the flying tourbillon with the chronograph function in a single integrated movement (Cal. 2952), requiring both complications to coexist within a 41mm case at a manageable profile — an engineering achievement that relatively few manufacturers have attempted and fewer have resolved elegantly. The collection launched in white gold with blue and black dial options; the most coveted configuration is the pink gold case with black ceramic bezel, produced in a single limited edition of 50 pieces. That 50-piece reference (26399NR) trades firmly above retail in any condition and represents among the Code 11.59's most collectible references. All Flying Tourbillon Chronograph configurations are purchased immediately.

The Code 11.59 perpetual calendar family spans two generations of movement architecture. The original Cal. 5134 references (ref. 26394, launched 2019) deliver instant-jump displays for day, date, month, and leap year cycle; the white gold blue aventurine dial is the most sought configuration. In 2025, Audemars Piguet introduced the new Cal. 7138 — a 422-component movement, just 4.1mm thick, engineered over five years and protected by five patents, with a single "all-in-one" crown replacing the traditional case-side correctors, making the perpetual calendar adjustable without tools for the first time. The Cal. 7138 powers both the 150th-anniversary 41mm ref. 26494BC (150 pieces, smoked blue dial, moonphase) and the first-ever 38mm perpetual calendar in the Code 11.59 (ref. 26441OR, green embossed dial, NASA moonphase). A new openworked perpetual calendar (ref. 26443NB, Cal. 7139, WG/black ceramic) reveals the movement architecture through a sapphire dial. All perpetual calendar configurations across both caliber generations are actively purchased.

The Starwheel complication belongs to a small group of watches in which the display of time itself is reimagined. Three satellite discs, each bearing hour numerals for four consecutive hours, orbit the dial on a planetary gear system driven by the Cal. 4310. As each disc completes its arc, the next rotates into position. Minutes are read from a fixed pointer against a minutes chapter ring at the outer edge of the dial. The result is a watch that tells time through a form of celestial mechanics — entirely readable, entirely unconventional. The Code 11.59 Starwheel (ref. 15212) appears in white gold with black ceramic bezel, pink gold with black ceramic bezel, and with a blue aventurine dial that makes the rotating discs appear to float in a starfield. In 2025, a new configuration (ref. 15212NR, pink gold with black ceramic, black aventurine dial) expanded the family further. The Starwheel has developed a dedicated following within the Code 11.59 collector community and holds its value reliably.

The Minute Repeater Supersonnerie (Cal. 2953) strikes the hours, quarter-hours, and minutes on demand via a slide activator in the case band, producing an acoustic result that distinguishes it from standard repeating watches. The Supersonnerie designation denotes AP's patented acoustic resonance architecture, in which the case construction itself — the choice of metal, the geometry of internal chambers, the attachment of the movement to the case — is engineered to function as a resonator, amplifying and projecting the striking mechanism's tone. The result is a subjectively more vivid, more present sound than most repeaters produce. The flagship execution is the white gold with blue Grand Feu enamel dial; the pink gold version offers a warmer palette; the ceramic case with sapphire-crystal dial (making the case effectively transparent to the movement) represents the most technically provocative configuration. All Minute Repeater Supersonnerie references are purchased at premium levels.

The Grande Sonnerie Carillon Supersonnerie (Cal. 2956) is among the most complex striking watch movements in current production. Unlike a minute repeater, which strikes only on demand, a grande sonnerie strikes the hours and quarter-hours automatically as time passes — the watch announces the time continuously throughout the day. The carillon mechanism uses three gongs and three hammers tuned to different pitches, producing chimes in three-note chords rather than the simpler two-note pattern of a standard repeater. The Supersonnerie acoustic architecture, adapted from the Minute Repeater, further enhances projection and resonance. The 498-component Cal. 2956 requires extraordinary skill to set up, regulate, and service. Each example in the Anita Porchet Grand Feu enamel series features a dial hand-painted by the master enameler herself, making every watch unique. The 150th anniversary opal dial series and the ceramic/yellow gold skeleton configuration round out the family. All Grande Sonnerie references are purchased promptly at correct market levels.

The RD#4 Ultra-Complication Universelle (Cal. 1000) is among the most complex wristwatches ever produced by any manufacturer. Its 23 complications — including perpetual calendar, minute repeater, grande sonnerie, split-seconds chronograph, equation of time, sunrise and sunset times, and a secular perpetual calendar accurate to the Gregorian correction cycle — required Audemars Piguet's research and development team to build an entirely new caliber with 1,155 individual components, all contained within a 41mm case and 14.7mm height. The watch is produced in white gold with black or beige dials and in pink gold with skeleton and silver dials. Production is extremely limited and demand consistently exceeds supply; examples rarely reach the secondary market.
