Audemars Piguet Code 11.59 Chronograph Steel — Blue Dial | Ref. 26393ST.OO.A348KB.01

Released as part of the 2023 Code 11.59 expansion, Ref. 26393ST brings the collection's celebrated three-part case architecture to stainless steel, making the manufacture's integrated flyback chronograph accessible to a wider audience without diluting a single point of horological ambition. The 41 mm round case is constructed from stainless steel throughout, its double-glareproofed sapphire crystal sealing the dial side while a closed caseback protects the movement within. The stainless steel bezel carries its finishing in the characteristic Code 11.59 manner — alternating bevelled planes creating light-catching transitions that reward close observation.

Calibre 4401, Audemars Piguet's in-house column-wheel flyback chronograph movement, operates at 28,800 vph with a 70-hour power reserve — architecture developed entirely within the Le Brassus manufacture over years of intensive research. The vertical clutch eliminates the dial jump associated with lateral-clutch designs, delivering chronograph activation that is both precise and visually clean. Index hour-markers define the chapter ring with the quiet confidence of a movement that needs no ornamentation to justify its presence; the overall composition reflects the Code 11.59's philosophy of architectural clarity.

The blue sunburst dial absorbs and reflects ambient light with a vibrancy that shifts from deep ocean tones at certain angles to brighter, more electric hues at others — a dial that lives differently in morning light than in evening ambience. Index markers sit flush to the surface with refined precision, while push-pieces flanking the crown activate the chronograph functions with the satisfying mechanical certainty that separates a great chronograph from a merely competent one. A black rubber strap with a pin buckle ensures the watch transitions effortlessly from a client meeting to a weekend on the water. At USD 29,999, this steel Code 11.59 Chronograph is among the most compelling entry points into Audemars Piguet's contemporary manufacture catalogue.
