The Code 11.59 Selfwinding Chronograph is the chronograph model in Audemars Piguet’s Code 11.59 line, built around the manufacture’s first in-house integrated flyback chronograph, calibre 4401. The Code 11.59 collection launched at SIHH in January 2019, and the 26393 chronograph debuted alongside it as the reference carrying the new movement.
Reference 26393NR.OO.A002KB.01 is a specific two-tone execution introduced in March 2024, when Audemars Piguet added seven new pink gold Code 11.59 models to the range. It pairs an 18-carat pink gold bezel, lugs, pushers and caseback with a black ceramic case middle and crown, under a smoked grey dial with a vertical satin-brushed base.
The two-tone pink gold and black ceramic aesthetic had first appeared on the steel Code 11.59 models in 2023 before extending to gold in 2024. The 26393NR is distinct from an earlier 2021 pink gold and black ceramic chronograph that used a gradient dial.
Within the collection this reference sits in the upper tier of the everyday-complication segment, a gold-and-ceramic chronograph positioned below the haute horlogerie Code 11.59 pieces such as the flying tourbillon, perpetual calendar and minute repeater.

The dial is smoked grey with a vertical satin-brushed base, darkening toward the edges to give the surface depth under light. The applied hour-markers and the applied 12 numeral are 18-carat pink gold, matched by pink gold hour and minute hands in the collection’s Royal Oak-derived style, treated with a luminescent coating.
The layout is a three-counter chronograph. The 30-minute counter sits at 9 o’clock, the 12-hour counter at 3 o’clock, and the constant small seconds at 6 o’clock, with the counters recessed into the dial. An instantaneous jumping date is displayed through a window at 4:30.
A black inner bezel rings the dial and carries a printed tachymeter scale calibrated on a base of 1000, reading toward the outer edge of the face. The gold-toned Audemars Piguet signature is applied below 12 o’clock, with “Swiss Made” printed at the base of the dial.
The case is 41 mm in diameter and 12.6 mm thick, built on the Code 11.59’s three-part architecture: an octagonal middle case, a round bezel, and open-worked lugs that connect to the bezel and caseback. On this reference the middle case and crown are black ceramic, while the bezel, lugs, pushers and caseback are 18-carat pink gold, finished with alternating satin-brushing and polishing.
The crystal is a double-curved sapphire with glareproofing, a domed profile that is a defining feature of the case design. The caseback is 18-carat pink gold with a glareproofed sapphire display window that exposes the movement.
The outer bezel is smooth, fixed pink gold and does not rotate. The chronograph is read against the fixed tachymeter scale on the black inner bezel rather than a rotating outer ring. Water resistance is rated at 30 metres.
The watch is fitted on a black rubber-coated strap with a woven textile pattern on its surface, secured by an 18-carat pink gold pin buckle. The strap is a single-piece configuration for this reference.
The pin buckle is solid 18-carat pink gold, matching the case’s gold elements. The Code 11.59 uses a fixed lug and integrated strap fitting rather than a quick-change system.
This exact reference carries the black textile-pattern strap. Other 26393 executions ship on straps colour-matched to their dials, and the full pink gold cased versions of the reference use alligator leather in some configurations.
The movement is the Audemars Piguet calibre 4401, an in-house integrated automatic chronograph. It is a flyback chronograph built with a column wheel and vertical clutch, constructed as a single integrated caliber rather than a base movement with an added chronograph module.
It runs at 28,800 vibrations per hour (4 Hz), holds 40 jewels, and delivers a 70-hour power reserve. Audemars Piguet’s current specification lists 381 parts. The movement is wound by a 22-carat pink gold openworked oscillating weight, visible through the sapphire caseback.
Functions are hours, minutes, small seconds, date, and the flyback chronograph with 30-minute and 12-hour counters. The chronograph is started and stopped with the upper pusher and reset with the lower pusher. The flyback function allows the running chronograph to be reset and restarted in a single press without first stopping it.
The case combines two principal materials. The middle case and crown are black ceramic, a hard, scratch-resistant material that holds its finish. The bezel, lugs, pushers, caseback and buckle are 18-carat pink gold, giving the watch its solid-gold external elements and weight in the wrist.
The crystal is sapphire, double-curved and glareproofed on the front, with a second glareproofed sapphire window in the pink gold caseback. The dial furniture, the applied hour-markers, the 12 numeral and the hands, is 18-carat pink gold. The strap is rubber-coated with a textile-pattern surface.
The overall material character is a contrast build: hard black ceramic against warm pink gold, with the gold concentrated on the visible external components and the ceramic reducing overall weight compared with an all-gold case.

Seller-mixed boxes, missing accessories, boutique or service packaging, and the packaging of the later 26393NR.OO.A002KB.02 reference do not constitute a box generation for this exact watch. A correct full set for 26393NR.OO.A002KB.01 is the modern Audemars Piguet Code 11.59 packaging described above.
At the time of sale this reference carried the Audemars Piguet International Sales Warranty, covering manufacturing defects for two years from the date of initial purchase. A five-year warranty term applies to Audemars Piguet watches purchased through the authorised network from 1 January 2017, subject to Audemars Piguet’s warranty-extension terms.
The warranty falls within Audemars Piguet’s modern warranty and digital-registration era. Coverage is documented on a physical International Warranty card that must be stamped, dated, and signed by the selling boutique or authorised dealer to be valid, alongside registration in the buyer’s Audemars Piguet account. The warranty follows the watch rather than the original owner, so it transfers on resale within its valid period.

This 2021-onward reference belongs entirely to the modern Audemars Piguet warranty generation, so its documentation follows the current digital-registration format. For an example sold new in 2024, the standard two-year term runs to 2026, while an example whose owner activated the extension carries coverage toward 2029. A correctly completed, dealer-stamped warranty card is the primary purchase document for a full-set example, and registration status in an Audemars Piguet account governs the extended term.
The reference is a current-catalogue model within the Code 11.59 collection. The Code 11.59 line itself has been in production since 2019, with this pink gold and black ceramic chronograph execution added in 2024.
At 41 mm across and 12.6 mm thick, the watch wears with real presence, and the thickness is driven by the domed sapphire crystal and the integrated chronograph movement rather than by the diameter alone. It suits medium to larger wrists.
The open-worked lugs curve down from the bezel and shorten the effective lug-to-lug reach, helping the case sit closer to the wrist than the raw diameter suggests. The black ceramic middle case reduces overall weight compared with a solid gold case of the same size, while the pink gold bezel, lugs and caseback keep a substantial feel.
The rubber-coated textile-pattern strap and pin buckle give the watch a more casual character than a leather-and-folding-clasp gold chronograph, making it a gold complication watch that reads as sporty rather than formal.
This reference is a single fixed configuration: a 41 mm case with a black ceramic middle and crown and 18-carat pink gold bezel, lugs, pushers and caseback, a smoked grey vertically satin-brushed dial with pink gold applied markers and hands, a black inner bezel with a tachymeter scale, and a black textile-pattern rubber-coated strap with an 18-carat pink gold pin buckle, powered by calibre 4401.
